Launch Your Own Search Engine: A Complete Guide to Self-Hosting SearXNG

The Search Privacy Problem Nobody's Talking About

Every search you make tells a story. That late-night medical question, the job search you're keeping quiet, the political topics you're curious about—someone's watching, recording, and building a profile of who you are.

Google processes over 8.5 billion searches per day. Bing, DuckDuckGo, and others handle billions more. Most of these platforms track what you search, when you search, and what you click on afterward. They connect this data to your identity through cookies, accounts, and device fingerprints.

The justification? Better search results, personalized ads, improved services. But at what cost?

Your search history reveals intimate details about your health concerns, financial situation, relationships, political views, and personal struggles. This data gets stored indefinitely, shared with advertisers, and sometimes handed over to authorities.

SearXNG offers a different approach. It's a metasearch engine you can host yourself, giving you complete control over your search privacy. No tracking. No profiling. No data collection. Just search results from multiple sources, aggregated in one place under your control.

This guide walks you through everything you need to know about setting up your own private search engine using SearXNG. Whether you're a privacy enthusiast, a tech hobbyist, or someone who just wants control over their digital life, you'll find practical steps to make it happen.

What Exactly Is SearXNG?

SearXNG belongs to a category called metasearch engines. Instead of crawling the web and building its own index like Google does, it sends your query to multiple search engines at once and combines the results.

Think of it as a search aggregator. You type in a query, and SearXNG queries Google, Bing, DuckDuckGo, Wikipedia, Reddit, YouTube, and potentially hundreds of other sources simultaneously. It then compiles the results, removes duplicates, and presents them to you in a unified interface.

The key difference? SearXNG doesn't log your searches. It doesn't create user profiles. It doesn't track which results you click. The search engines it queries only see anonymous requests coming from the SearXNG server, not from you personally.

How It Protects Your Privacy

When you search directly on Google, they know your IP address, browser fingerprint, and search history. They link this to your Google account if you're logged in. Over time, they build a detailed profile of your interests, behaviors, and demographics.

With SearXNG, the search engines only see requests from the SearXNG server. They can't identify you because:

  • Your IP address is hidden behind the server
  • Your browser fingerprint isn't transmitted
  • Each search appears to come from a different user
  • No cookies track you across searches
  • No account links searches together

SearXNG strips identifying information before forwarding queries and removes tracking elements from the results it returns to you.

Open Source Means Open Accountability

SearXNG's code is publicly available on GitHub. Anyone can review it, verify its privacy claims, and contribute improvements. This transparency matters because you can confirm it does what it claims.

The project has an active community of developers and privacy advocates who continuously improve it. Regular updates add new search sources, fix bugs, and enhance security.

Being open source also means you can modify it to fit your needs. Want to prioritize certain search engines? Change the interface design? Add custom filters? The code is yours to adapt.

What You Can Search With SearXNG

SearXNG can query up to 249 different search services across various categories:

  • General web search (Google, Bing, Yahoo, Brave Search)
  • Academic papers (Google Scholar, Semantic Scholar, arXiv)
  • Images and videos (Google Images, Bing Images, YouTube, Vimeo)
  • News sources (Google News, Bing News, Reddit)
  • Maps and locations (OpenStreetMap, Google Maps)
  • Music (Spotify, SoundCloud, Bandcamp)
  • Social media (Reddit, Twitter, Mastodon)
  • Code repositories (GitHub, GitLab)
  • Shopping (Amazon, eBay)
  • Files (Internet Archive, Library Genesis)

You control which engines get queried for each search type. Want scientific results? Enable academic sources. Looking for videos? Query multiple video platforms at once.

Public Instances vs Self-Hosting

Anyone can use SearXNG right now through public instances. Websites like searx.space list dozens of public SearXNG servers that anyone can access for free.

Public instances offer immediate privacy benefits over using Google directly. The instance operator sees your searches, but they typically don't log them, and the upstream search engines can't identify you personally.

The trade-off? You trust the instance operator to honor their privacy promises. You share server resources with other users, which can affect performance. Some instances block Tor users or restrict access during high traffic periods.

Self-hosting eliminates these concerns. You control the server. You know nobody logs your searches because you configured it. You get full performance because you're the only user. You can access it over Tor without restrictions.

Why Run Your Own Search Engine?

Self-hosting SearXNG gives you capabilities that public instances can't match. The benefits extend beyond privacy into customization, performance, and independence.

Complete Privacy Control

When you host SearXNG yourself, you own every aspect of the privacy equation. No logs exist unless you create them. No third party sees your searches at all.

You decide what data, if any, gets temporarily stored for functionality. You control which networks can access your instance. You determine whether to enable features that might impact privacy.

For people with serious privacy needs—journalists, activists, researchers, whistleblowers—this level of control can be necessary. Even for regular users who value privacy, knowing with certainty that nobody watches your searches brings peace of mind.

The privacy extends beyond just searches. SearXNG respects privacy in the results too. It rewrites links to remove tracking parameters, blocks third-party scripts, and can route traffic through Tor for additional anonymity.

Customization Without Compromise

Public instances use default configurations that work for most people. Your own instance lets you optimize for exactly what you need.

Want image searches to prioritize Flickr over Google Images? Configure it. Prefer scientific papers from arXiv over commercial publishers? Set those priorities. Need to exclude certain websites from all results? Add them to your blocklist.

You can customize the interface colors, fonts, and layout. Create different search categories for different types of queries. Set up keyboard shortcuts for faster searching. Add custom CSS to match your preferences.

The settings file controls everything from which languages display to how many results appear per page. You can enable experimental features, disable components you never use, and tune performance parameters for your hardware.

These customizations persist across sessions and devices when you host it yourself. With public instances, you reset to defaults if you clear cookies or switch browsers.

Performance Benefits

Public SearXNG instances handle searches from dozens or hundreds of users simultaneously. During peak times, this creates delays. Popular instances sometimes rate-limit users or return timeout errors when overloaded.

Your private instance serves only you (or your household/organization). Queries process immediately without waiting in queue. Results return faster because all server resources focus on your request.

You can also optimize for your network situation. Hosting SearXNG on your local network means sub-second response times for the web interface. Hosting it on a VPS close to your geographic location minimizes latency to upstream search engines.

Some users report their self-hosted instances feel faster than using Google directly, especially when searching multiple categories simultaneously. The aggregation happens server-side, so you see combined results without waiting for individual sources.

Practical Use Cases

Personal privacy represents the most common reason for self-hosting, but other scenarios benefit too.

Families can share a single instance that respects everyone's privacy without requiring separate accounts. Parents know their children's searches aren't being profiled for advertising. Teenagers get privacy without surveillance.

Small organizations and businesses can deploy SearXNG internally. Employees search without corporate concerns about Google knowing their research topics. The organization avoids leaking strategic information through search behavior.

Self-hosters and homelab enthusiasts often include SearXNG alongside other self-hosted services like Nextcloud, Jellyfin, or Home Assistant. It completes the stack of privacy-respecting alternatives to cloud services.

Students and researchers use SearXNG to query academic databases without paywalls and track search results across multiple scholarly sources. Teachers deploy instances for classroom use where student searches shouldn't create advertising profiles.

What You Need Before Starting

Setting up SearXNG requires some technical knowledge and resources, but less than you might expect. Most people with basic Linux familiarity can have it running within an hour.

Server Requirements

SearXNG runs efficiently on modest hardware. The minimum specs for personal use:

  • CPU: 1 core (2+ cores better for multiple users)
  • RAM: 512MB minimum (1GB recommended)
  • Storage: 1GB for the application and dependencies
  • Network: stable internet connection

These requirements fit easily on a Raspberry Pi, old laptop, or budget VPS. Hosting providers like Hetzner, DigitalOcean, or Linode offer suitable servers starting around $5 monthly.

More powerful hardware improves response times when querying many search engines simultaneously. If you plan to serve multiple users or enable all 249 search sources, consider 2GB+ RAM.

Operating System Compatibility

SearXNG officially supports Linux distributions. The most common choices:

  • Ubuntu 20.04 or 22.04 LTS
  • Debian 11 or 12
  • Fedora recent versions
  • Arch Linux

Docker deployment works on any OS that runs Docker, including Windows and macOS. This makes it the easiest option for non-Linux users.

The installation scripts target Debian-based systems but adapt easily to others. Manual installation works on any Linux distribution with Python 3.8 or newer.

Where To Host It

You have several deployment options, each with trade-offs:

Home server or NAS: Most private option. No monthly costs after initial hardware. Requires stable internet and perhaps dynamic DNS if your IP changes. Port forwarding needed for external access.

Raspberry Pi: Low power consumption, quiet, small footprint. Sufficient for personal use. Limited performance under heavy load.

VPS (Virtual Private Server): Easy setup, professional infrastructure, fixed costs. Requires trusting the hosting provider with server access. Good bandwidth and uptime.

Existing home lab infrastructure: If you already run a home server, NAS, or virtualization host, adding SearXNG costs nothing extra. Fits naturally into self-hosted ecosystems.

Cloud platforms: AWS, Google Cloud, Azure offer free tiers that can run SearXNG. Ironic to use Google's infrastructure for private search, but technically possible.

Domain and Access Planning

You can run SearXNG purely locally at http://localhost or http://192.168.x.x on your network. This works fine for personal use from home.

For access from anywhere, you need either:

  • A domain name pointing to your server's IP
  • Dynamic DNS service if your home IP changes
  • Cloudflare Tunnel or similar tunneling service
  • VPN into your home network

SSL certificates provide encrypted connections. Let's Encrypt offers free certificates if you have a domain name. Self-signed certificates work for local use but trigger browser warnings.

Time and Skills Expected

If you follow the Docker installation method with basic Linux knowledge:

  • Initial setup: 30-60 minutes
  • Configuration tweaking: 1-2 hours
  • Ongoing maintenance: 15 minutes monthly

Manual installation takes longer but teaches you more:

  • Initial setup: 2-3 hours
  • Configuration: 2-3 hours
  • Understanding the architecture: 3-5 hours

The learning curve isn't steep if you've installed Linux software before. Command-line comfort helps. Reading configuration files and basic troubleshooting skills matter most.

Choosing Your Installation Approach

SearXNG offers three main installation paths. Picking the right one depends on your technical comfort level, how much control you want, and how much time you'll invest.

Docker Container Method

Docker packages SearXNG with all dependencies in a container. You download the image and run a few commands. The container handles the Python environment, web server, and configuration.

This approach wins for simplicity. The SearXNG team maintains official Docker images for multiple processor architectures (x86, ARM). Updates happen by pulling a new image and restarting the container.

Docker also isolates SearXNG from your host system. If something breaks, you delete the container and start fresh without affecting other software. The contained environment means fewer dependency conflicts.

Most people should start here. You can always migrate to manual installation later if you want more control.

When to choose Docker:

  • First time hosting SearXNG
  • Want fast setup with minimal troubleshooting
  • Run other Docker containers already
  • Value easy updates over deep customization
  • Use non-Linux OS (Windows, macOS)

Installation Scripts

The SearXNG project provides shell scripts that automate manual installation. Run the script, answer a few prompts, and it handles downloading code, configuring the web server, and starting services.

Scripts fall between Docker convenience and manual control. They set up a native installation but save you from typing commands yourself. You can read the script to understand what it does.

The scripts target Debian/Ubuntu systems primarily. They work on others with modifications. Some users find scripts less predictable than Docker because they modify your system directly.

When to choose scripts:

  • Prefer native installation over containers
  • Want automated setup without Docker overhead
  • Need customizations that containers complicate
  • Run Debian or Ubuntu specifically
  • Value learning the installation process

Manual Step-by-Step Setup

Installing manually means following the documentation and executing each command yourself. You create users, set permissions, configure the web server, and start services individually.

This takes longest but provides maximum understanding. You see exactly where files live, how services connect, and what each configuration does. Troubleshooting becomes easier because you built it.

Manual installation offers complete control over every aspect. Choose specific software versions, customize the directory structure, integrate with existing systems your way. The trade-off is time and complexity.

When to choose manual installation:

  • Want deep understanding of SearXNG architecture
  • Need significant customizations
  • Integrating with complex existing infrastructure
  • Enjoy learning systems administration
  • Have time for troubleshooting if issues arise

Method Comparison

Ease of use: Docker > Scripts > Manual

Setup speed: Docker (30 min) > Scripts (45 min) > Manual (2+ hours)

Customization: Manual > Scripts > Docker

Update process: Docker (pull new image) > Scripts (rerun script) > Manual (git pull + restart)

Troubleshooting difficulty: Manual (you know what you built) > Docker (contained issues) > Scripts (system-level changes)

Resource usage: Manual (native, efficient) > Docker (small overhead) > Scripts (native, efficient)

Most users benefit from starting with Docker. You get SearXNG running quickly, learn how it works, and can always migrate to manual installation if needed. The Docker approach removes common setup headaches while still allowing configuration customization through the settings file.

Installing SearXNG Step by Step

This section walks through Docker installation since it works for most situations. The process applies whether you're on a home server, Raspberry Pi, or VPS.

Preparing Your System

Start with a clean, updated system. Connect to your server via SSH or directly if it's local.

Update your system packages:

sudo apt update && sudo apt upgrade -y

Install Docker if not already present:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

Add your user to the docker group so you don't need sudo for docker commands:

sudo usermod -aG docker $USER

Log out and back in for the group change to take effect.

Install Docker Compose for easier multi-container management:

sudo apt install docker-compose -y

Create a directory for SearXNG:

mkdir -p ~/searxng
cd ~/searxng

Creating the Configuration

SearXNG uses a settings.yml file for configuration. Create it with a text editor:

nano settings.yml

Start with this basic configuration:

use_default_settings: true

general:
  instance_name: "My Private Search"
  
server:
  secret_key: "CHANGE_THIS_TO_RANDOM_STRING"
  limiter: false
  
search:
  safe_search: 0
  autocomplete: ""
  
ui:
  default_theme: simple
  default_locale: en

The secret_key should be a random string. Generate one with:

openssl rand -hex 32

Save the file and exit (Ctrl+X, then Y, then Enter in nano).

Creating the Docker Compose File

Create a docker-compose.yml file:

nano docker-compose.yml

Add this configuration:

version: '3'

services:
  searxng:
    image: searxng/searxng:latest
    container_name: searxng
    ports:
      - "8080:8080"
    volumes:
      - ./settings.yml:/etc/searxng/settings.yml:ro
    environment:
      - SEARXNG_BASE_URL=http://localhost:8080/
    restart: unless-stopped

This tells Docker to:

  • Use the official SearXNG image
  • Map port 8080 from container to host
  • Mount your settings file into the container
  • Restart automatically if it crashes

Save and exit.

Starting SearXNG

Start the container:

docker-compose up -d

Docker downloads the image (first time only) and starts SearXNG. Check it's running:

docker-compose logs

You should see startup messages without errors.

Testing Your Installation

Open a browser and navigate to:

http://YOUR_SERVER_IP:8080

If running locally, use:

http://localhost:8080

You should see the SearXNG search interface. Try searching for something. Results should appear from multiple engines.

If it doesn't load, check the logs:

docker-compose logs searxng

Common issues include port conflicts (change 8080 to another port) or configuration syntax errors (check your settings.yml formatting).

Setting Up a Reverse Proxy

Running on port 8080 works for testing but you'll want proper HTTPS access. A reverse proxy handles this.

Install nginx:

sudo apt install nginx certbot python3-certbot-nginx -y

Create an nginx configuration:

sudo nano /etc/nginx/sites-available/searxng

Add this configuration (replace search.yourdomain.com):

server {
    listen 80;
    server_name search.yourdomain.com;

    location / {
        proxy_pass http://localhost:8080;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

Enable the configuration:

sudo ln -s /etc/nginx/sites-available/searxng /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

Get an SSL certificate:

sudo certbot --nginx -d search.yourdomain.com

Follow the prompts. Certbot configures HTTPS automatically.

Update your docker-compose.yml base URL:

environment:
  - SEARXNG_BASE_URL=https://search.yourdomain.com/

Restart SearXNG:

docker-compose restart

Access your instance at https://search.yourdomain.com

Making It Start Automatically

Docker Compose with restart: unless-stopped handles automatic startup. When your server reboots, Docker starts the container automatically.

Verify this works:

sudo reboot

After reboot, check if SearXNG is running:

docker ps

You should see the searxng container listed.

Configuring SearXNG for Your Needs

The settings.yml file controls every aspect of how SearXNG works. This section covers the most useful configuration options.

Understanding the Settings Structure

The settings file uses YAML format. Indentation matters—use spaces, not tabs. Main sections include:

  • general: instance-wide settings
  • search: search behavior configuration
  • server: web server and security settings
  • ui: interface customization
  • engines: which search sources to use

The setting use_default_settings: true loads default configurations, then your custom settings override specific values. This keeps your configuration file short and maintainable.

Selecting Search Engines

By default, SearXNG queries many engines. You might want fewer for faster results or more for comprehensive coverage.

Add an engines section to enable specific ones:

engines:
  - name: google
    disabled: false
    
  - name: bing
    disabled: false
    
  - name: duckduckgo
    disabled: false
    
  - name: wikipedia
    disabled: false

Or disable engines you don't want:

engines:
  - name: google
    disabled: true

Some engines require API keys. For example, enabling Wolfram Alpha:

engines:
  - name: wolframalpha
    disabled: false
    api_key: 'YOUR_API_KEY_HERE'

Check the SearXNG documentation for which engines need API keys and how to obtain them.

Customizing the Interface

Change the theme and language:

ui:
  default_theme: simple
  default_locale: en
  theme_args:
    simple_style: dark

Available themes include simple, pix-art, and others. The simple theme offers both light and dark styles.

Control how many results display:

search:
  default_page_size: 20

Enable or disable autocomplete:

search:
  autocomplete: 'google'

Options include google, dbpedia, duckduckgo, or leave empty to disable.

Privacy and Security Settings

Disable logging completely:

server:
  limiter: false
  image_proxy: true

The image_proxy setting routes images through your server instead of loading directly from sources, hiding your IP from image hosts.

Set up rate limiting if others access your instance:

server:
  limiter: true
  
limiter:
  rate_limit:
    window: 60
    max_requests: 20

This allows 20 searches per 60-second window per IP address.

Enable additional security headers:

server:
  http_protocol_version: "1.1"
  method: "POST"

Using POST for searches prevents queries from appearing in web server logs.

Performance Tuning

Adjust timeout values if searches run slow:

outgoing:
  request_timeout: 3.0
  max_request_timeout: 15.0

Lower timeouts return results faster but might miss slow engines. Higher timeouts wait longer but get more complete results.

Configure concurrent requests:

outgoing:
  max_redirects: 3
  pool_connections: 100
  pool_maxsize: 10

These control how many simultaneous connections SearXNG makes to search engines.

Enable caching for better performance:

server:
  cache:
    memory:
      enabled: true
      size: 10485760

This caches 10MB of search results in memory for faster repeated queries.

Plugin System

SearXNG includes plugins that add functionality. Enable them in settings:

plugins:
  - 'Hash plugin'
  - 'Self Information'
  - 'Tracker URL remover'
  - 'Hostname replace'

Useful plugins:

  • Tracker URL remover: strips tracking parameters from results
  • Hostname replace: redirects sites to privacy-respecting alternatives
  • Hash plugin: calculates hashes directly in search
  • Self Information: shows your IP and headers

Configure specific plugins:

hostname_replace:
  '(.*\.)?youtube\.com$': 'invidious.example.com'
  '(.*\.)?twitter\.com$': 'nitter.example.com'

This automatically redirects YouTube to Invidious and Twitter to Nitter.

Creating Search Categories

Customize which engines run for different search types:

engines:
  - name: google
    categories: general
    
  - name: google images
    categories: images
    
  - name: google news
    categories: news

Categories help organize results. When you search, select which category to query.

Advanced Features and Integration

Once you have SearXNG running, several advanced features expand its capabilities.

Setting Up Tor Access

Running SearXNG as a Tor hidden service provides additional anonymity. Install Tor:

sudo apt install tor -y

Edit the Tor configuration:

sudo nano /etc/tor/torrc

Add these lines:

HiddenServiceDir /var/lib/tor/searxng/
HiddenServicePort 80 127.0.0.1:8080

Restart Tor:

sudo systemctl restart tor

Find your onion address:

sudo cat /var/lib/tor/searxng/hostname

This gives you a .onion address that works in Tor Browser. Your SearXNG instance is now accessible anonymously through Tor.

Using the Search API

SearXNG provides a JSON API for programmatic access. Enable it in settings:

search:
  formats:
    - html
    - json

Query the API with curl:

curl "http://localhost:8080/search?q=test&format=json"

This returns search results as JSON data. You can integrate this into scripts, applications, or other tools.

The API accepts parameters:

  • q: search query
  • categories: which category to search
  • engines: specific engines to use
  • language: result language
  • pageno: page number

Example searching only Wikipedia:

curl "http://localhost:8080/search?q=python&engines=wikipedia&format=json"

Browser Integration

Make SearXNG your default search engine in browsers.

Firefox:

Visit your SearXNG instance, click the address bar, and look for a green plus icon. Click it to add SearXNG as a search option. Go to Settings > Search and set it as default.

Chrome/Brave:

Go to Settings > Search engine > Manage search engines. Click Add, fill in:

  • Name: SearXNG
  • Keyword: s
  • URL: https://search.yourdomain.com/search?q=%s

Set it as default.

OpenSearch format:

SearXNG supports OpenSearch for automatic discovery. Browsers detect it when you visit the instance.

Supporting Multiple Users

If family members or an organization will use your instance, consider these adjustments.

Increase container resources in docker-compose.yml:

deploy:
  resources:
    limits:
      memory: 2G
      cpus: '2'

Enable rate limiting to prevent abuse:

server:
  limiter: true
  
limiter:
  rate_limit:
    window: 60
    max_requests: 30

Consider authentication if you want restricted access. SearXNG doesn't have built-in authentication, but you can use nginx basic auth:

sudo apt install apache2-utils
sudo htpasswd -c /etc/nginx/.htpasswd username

Add to your nginx configuration:

location / {
    auth_basic "SearXNG";
    auth_basic_user_file /etc/nginx/.htpasswd;
    proxy_pass http://localhost:8080;
}

Restart nginx:

sudo systemctl restart nginx

Now accessing SearXNG requires username and password.

Monitoring and Logging

Check which search engines work properly:

docker-compose logs | grep ERROR

This shows failed engine requests. Some engines block automated queries or have API limits.

Monitor resource usage:

docker stats searxng

Shows real-time CPU, memory, and network usage for the container.

Set up log rotation to prevent disk filling:

docker-compose logs --tail 100

Docker automatically rotates logs, but you can configure limits in docker-compose.yml:

logging:
  driver: "json-file"
  options:
    max-size: "10m"
    max-file: "3"

This keeps the last 30MB of logs (3 files at 10MB each).

Keeping SearXNG Updated

SearXNG receives regular updates with new features, bug fixes, and security patches. Staying current keeps your instance running smoothly.

Updating Docker Installations

Docker makes updates simple. Pull the latest image:

cd ~/searxng
docker-compose pull

This downloads the newest version. Restart with the new image:

docker-compose down
docker-compose up -d

Your settings persist because they're in the mounted settings.yml file, not the container.

Check the new version works:

docker-compose logs

The entire update takes under a minute with no complex migration steps.

Backup Strategies

Before updating, back up your configuration:

cp settings.yml settings.yml.backup

For Docker installations, that's the only file you need. The container is disposable and recreated from the image.

If you've customized themes or templates, back up those too:

tar czf searxng-backup.tar.gz settings.yml docker-compose.yml

Store backups somewhere safe, perhaps in cloud storage or on another machine.

Checking for New Releases

Watch the SearXNG GitHub repository for new releases:

https://github.com/searxng/searxng/releases

The release notes explain what changed, what features were added, and if any configuration updates are needed.

Most updates don't require settings changes. Occasionally a new feature needs enabling or a deprecated setting needs updating.

Managing Configuration Changes

When updates add new engines or features, your existing settings.yml continues working. New options use defaults until you explicitly configure them.

Read release notes to learn about new capabilities. If something interests you, add it to your settings file.

Compare your settings with the default configuration occasionally:

docker run --rm searxng/searxng:latest cat /etc/searxng/settings.yml

This shows the current default settings. You can spot new options and decide if you want them.

Troubleshooting Common Problems

Most issues have simple solutions. This section covers the problems people encounter most often.

Installation Issues

Docker command not found: Install Docker using the get.docker.com script or your distribution's package manager.

Permission denied when running Docker: Add your user to the docker group and log out/in.

Port 8080 already in use: Change the port in docker-compose.yml to something else like 8081:8080.

Container starts then stops immediately: Check logs with docker-compose logs. Usually indicates a configuration error in settings.yml.

Search Functionality Problems

No results appear: Some engines block automated queries. Check which engines work at your instance's /stats page. Disable non-working ones in settings.yml.

Searches are very slow: Lower the timeout values in settings.yml or disable slow engines. Check your server's internet connection speed.

CAPTCHAs appearing: Some engines show CAPTCHAs when they detect automated queries. Disable those engines or reduce query frequency. Using residential IP addresses instead of datacenter IPs helps.

Specific engine missing: Not all 249 engines enable by default. Add the engine explicitly in settings.yml to use it.

Configuration Errors

Settings not applying: Check YAML indentation uses spaces not tabs. Validate syntax with an online YAML validator. Restart the container after settings changes.

Secret key warning: Generate a proper secret key with openssl rand -hex 32 and add it to settings.yml.

Theme not loading: Verify the theme name matches exactly. Check the logs for template errors.

Plugins not working: Some plugins conflict. Enable them one at a time to identify issues.

SSL and Access Issues

Certificate errors: Let's Encrypt certificates need renewal every 90 days. Certbot handles this automatically if configured correctly.

Can't access from external network: Check firewall rules allow port 80/443. Verify port forwarding if behind a router. Confirm DNS points to your IP.

Mixed content warnings: Happens when accessing HTTPS SearXNG that queries HTTP engines. Configure image_proxy to solve this.

Where to Get Help

Check the official documentation first:

https://docs.searxng.org

Search GitHub Issues for similar problems:

  • SearXNG version number
  • Installation method (Docker, script, manual)
  • Operating system and version
  • Relevant log excerpts
  • Configuration sections that might relate to the issue

Most problems have been encountered before. Someone in the community likely knows the solution.

Taking Control of Your Search Privacy

Setting up SearXNG represents more than just installing software. It's about reclaiming control over a fundamental internet activity.

Every day, billions of people hand over intimate details about their thoughts, interests, and concerns to companies that profit from that information. They accept this because alternatives seem too complicated or because they don't realize the extent of tracking.

You now have the knowledge to break that pattern. The technical barriers aren't as high as they appear. An hour of setup gives you a private search engine that works as well as the mainstream options, without the surveillance.

Self-hosting puts you in charge. Nobody watches your searches. Nobody builds a profile. Nobody sells your data. The privacy comes from the architecture itself, not from trusting promises in a privacy policy.

Beyond privacy, you gain technical skills. Understanding how search engines work, even at this metasearch level, demystifies a core internet service. You learn about web servers, reverse proxies, containerization, and network security. These skills transfer to other projects.

The SearXNG community continues improving the software. New search sources get added. Performance gets optimized. Security strengthens. By running your own instance, you benefit from this collective effort while maintaining independence.

Start small if the full setup seems overwhelming. Use a public instance first to see if you like SearXNG. Then move to Docker on a VPS when you're ready. Add features gradually as you learn.

Or dive in completely. Install it on a Raspberry Pi this weekend. Configure your preferred engines. Set it as your browser's default search. Experience what searching feels like without tracking.

The web doesn't have to be a surveillance network. Tools like SearXNG prove that privacy and functionality can coexist. You don't sacrifice search quality for privacy. You gain both.

Your search history is yours alone. Keep it that way.

Technical Terms Explained

Metasearch Engine: A search service that queries multiple other search engines and combines their results, rather than maintaining its own index.

Reverse Proxy: A server that sits in front of web servers and forwards client requests to them, often used for SSL termination and load balancing.

Container: A lightweight, standalone package containing an application and all its dependencies, isolated from the host system.

uWSGI: A web server gateway interface that connects web servers like Nginx to Python applications.

YAML: A human-readable data serialization format commonly used for configuration files.

API Key: A unique identifier used to authenticate requests to a service's application programming interface.

SSL/TLS Certificate: Digital certificate that authenticates a website's identity and enables encrypted connections.

Rate Limiting: Controlling how many requests a user can make to a service within a given time period.

Onion Service: A website accessible only through the Tor network, providing anonymity for both the host and visitors.

Instance: A specific deployment or installation of software running on a server.

Frequently Asked Questions

How much does it cost to run SearXNG?

The software itself is free. Hosting costs depend on your approach. A Raspberry Pi at home costs electricity only (a few dollars yearly). A basic VPS runs $5-10 monthly. Reusing existing hardware costs nothing extra.

Can I really trust that my searches are private?

When you host it yourself, you control the code and server. You can verify in the logs that nothing gets recorded. The open-source code can be audited. Public instances require trusting the operator, but self-hosting eliminates that trust requirement.

Will search results be worse than Google?

SearXNG can query Google along with many other engines. You often get better results because you're seeing aggregated information from multiple sources. Some users report preferring SearXNG results over any single search engine.

Is it legal to host a search engine?

Yes. SearXNG simply queries public search engines on your behalf. It's like using multiple search engines manually and comparing results, but automated. No laws prohibit this.

Can I search as fast as commercial search engines?

Usually yes. Your private instance often responds faster than public instances because you're not sharing resources. Network latency between your server and search APIs affects speed, but most users find it comparable to direct searches.

What happens if a search engine blocks my IP?

Some engines implement rate limiting or blocking. Disable problematic engines in your configuration. Using multiple engines means results still appear even if one blocks requests. Residential IP addresses face fewer blocks than datacenter IPs.

Do I need programming knowledge?

Basic command-line comfort helps, but you don't need programming skills. Following the Docker installation instructions requires copying and pasting commands and editing text files. More advanced customizations benefit from understanding Python.

Can I monetize my public instance?

The SearXNG license allows this, but the community generally discourages it. The project exists to provide privacy-respecting search without commercial incentives. Running ads or tracking users defeats the purpose.

How do I know which engines work?

Visit the /stats page on your instance (e.g., https://search.yourdomain.com/stats). This shows every enabled engine, success rates, average response times, and recent errors. Disable consistently failing engines.

Can I use this on mobile devices?

Yes. Access your instance through any mobile browser. The interface works on phones and tablets. Some users add it to their home screen for quick access. You can't install it as a native app, but the web interface works fine.

What about updates when I'm on vacation?

SearXNG runs for months without attention. Security updates matter most. Consider enabling automatic Docker image updates via Watchtower if you'll be away from your server for extended periods.

Can multiple people use my instance simultaneously?

Yes. Configure appropriate resources and rate limiting. A modest server handles 5-10 concurrent users easily. Organizations successfully run SearXNG for dozens of users.

Does it work with voice search?

Not built-in. Voice search requires integration with voice recognition services. Some users configure external voice-to-text tools that send queries to their SearXNG instance, but this requires additional setup.

How do updates affect my configuration?

Your settings.yml persists across updates. Most updates don't break existing configurations. Release notes mention when breaking changes occur, which is rare.

Can I contribute to SearXNG development?

Absolutely. The project welcomes code contributions, documentation improvements, translation help, and bug reports. Check the GitHub repository for contribution guidelines.

Final Thoughts

The internet started as a decentralized network where individuals controlled their own piece of the infrastructure. Over time, centralization concentrated power in the hands of a few massive companies.

Search exemplifies this centralization. Most people use one of three or four search engines, all operated by corporations with business models built on data collection.

SearXNG represents a counter-movement. It returns control to individuals. You host the infrastructure. You decide the rules. You keep your data.

This guide gave you the roadmap. The technology works. The community supports it. The barriers to entry are lower than ever.

What you do with this information is up to you. You can continue using commercial search engines that track every query. Or you can spend an hour setting up your own privacy-respecting alternative.

The choice has always been yours. Now you have the knowledge to act on it.

Your searches belong to you. Not to advertisers. Not to data brokers. Not to surveillance systems. Just you.

Take control. Install SearXNG. Search freely.
