SearXNG: Complete Guide & Tutorial

Introduction to SearXNG: Your Privacy-First Metasearch Engine

In an era where your every online query is tracked, profiled, and sold, finding a search engine that respects your privacy is becoming increasingly difficult. Enter SearXNG, a free, open-source metasearch engine that acts as your personal gateway to the internet without compromising your anonymity. Unlike Google, Bing, or DuckDuckGo, SearXNG does not track your searches, build a profile of your interests, or censor results. Instead, it aggregates results from over 70 search services, including Google, Bing, Wikipedia, Reddit, and many more, presenting them in a clean, unified interface.

SearXNG is not just another search engine; it is a tool you can fully control. You can use the official public instance at https://searxng.org, or you can self-host it on your own server for complete data sovereignty. This tutorial will guide you from absolute beginner to confident user, covering everything from first-time setup to advanced configuration. Whether you are a privacy enthusiast, a developer, or simply someone tired of being tracked, this guide will help you unlock the full potential of SearXNG.

Getting Started with SearXNG

Option 1: Using a Public Instance (Easiest)

The quickest way to start using SearXNG is through a public instance. Visit https://searxng.org and click on the “Instances” link. You will find a list of community-run servers. Choose one that is geographically close to you for faster response times. Most public instances are free to use and require no registration. Simply type your query into the search box, and you are ready to go.

Option 2: Self-Hosting SearXNG (For Maximum Privacy)

Self-hosting gives you complete control over your data. You will need a server (a VPS from DigitalOcean, Linode, or a Raspberry Pi at home) and basic knowledge of the command line. Here is a beginner-friendly approach using Docker, which simplifies the process enormously.

• Step 1: Install Docker and Docker Compose – On your server, run the official installation scripts from Docker’s website. For Ubuntu, this is typically sudo apt update && sudo apt install docker.io docker-compose.
• Step 2: Create a Directory – mkdir searxng && cd searxng
• Step 3: Create a docker-compose.yml File – Use a text editor (like nano) to create a file with the following content:

version: '3'
services:
  searxng:
    image: searxng/searxng:latest
    ports:
      - "8080:8080"
    volumes:
      - ./searxng-data:/etc/searxng
    environment:
      - SEARXNG_BASE_URL=https://your-domain.com
    restart: unless-stopped

• Step 4: Run the Container – Execute sudo docker-compose up -d. Your SearXNG instance will be available at http://your-server-ip:8080.
• Step 5: Configure a Reverse Proxy (Optional but Recommended) – Use Nginx or Caddy to add HTTPS encryption and a custom domain. This step is crucial for privacy because it encrypts your traffic.

Note for beginners: If self-hosting seems daunting, stick with a public instance for now. You can always self-host later once you are comfortable with server administration.

Key Features of SearXNG

1. Aggregation from 70+ Search Services

SearXNG does not have its own index of the web. Instead, it sends your query to multiple search engines simultaneously (like Google, Bing, DuckDuckGo, Qwant, Wikipedia, and many specialized ones) and combines the results. This means you get the best of all worlds without being locked into one provider’s algorithm or biases.

2. No Tracking or User Profiling

This is the core promise of SearXNG. The engine does not set tracking cookies, does not log your IP address permanently, and does not build a profile of your search history. When you use a public instance, the instance operator may see that a search was made, but they cannot associate it with you personally. When you self-host, you are the only one who sees the logs, and you can configure them to be deleted automatically.

3. Self-Hostable for Complete Privacy Control

By running SearXNG on your own server, you ensure that no third party ever touches your search data. You can also customize the engine to use only the backends you trust, block certain domains, and set your own privacy policies.

4. Configurable Search Categories and Engines

You are not forced to search the entire web every time. SearXNG lets you choose from categories like “General”, “Images”, “Videos”, “News”, “Files”, “Social Media”, and more. Within each category, you can enable or disable specific engines. For example, you can set Images to only search Bing and Flickr, while News only searches Reddit and Hacker News.

5. Multiple Output Formats

Beyond the standard HTML web interface, SearXNG can output results in JSON (perfect for developers and automation), RSS (for feed readers), and CSV. This makes it an incredibly powerful tool for data scraping, monitoring, and integration with other applications.

6. Built-in Proxy for Anonymous Access

When you click on a result, SearXNG can route your request through its own built-in proxy. This hides your real IP address from the target website. The proxy is optional and can be toggled on a per-result basis. It is useful for accessing content that might be blocked in your region, but be aware that it may slow down page loads.

How to Use SearXNG: A Step-by-Step Guide

Performing Your First Search

Navigate to your SearXNG instance. You will see a simple, minimalist search bar. Type your query (e.g., “best privacy tools 2025”) and press Enter. The results page will show a mix of sources: web pages from Google, discussions from Reddit, and maybe a Wikipedia entry. Notice the absence of ads and tracking scripts.

Using Categories to Refine Results

Look for the category tabs above the search bar. By default, “General” is selected. Click on Images to search only for pictures, or News to find recent articles. You can also click on the gear icon (Settings) to customize which engines are used for each category. For example, if you want Images from Flickr only, disable all other image engines.

Configuring Search Engines

Click on the “Preferences” link (usually a gear icon or a link in the top right corner). Under the Engines tab, you will see a long list of search services. Each has a checkbox. Uncheck any engine you do not want to use. You can also set a “Weight” for each engine—higher weight means its results appear more prominently. This is useful if you trust a particular source more than others.

Using the Built-in Proxy

On the search results page, each link has a small icon next to it (often a shield or a “proxy” label). Clicking this icon will open the page through SearXNG’s proxy. Your real IP address will not be sent to the target website. You can also enable the proxy for all links by going to Preferences > General > “Open result in new tab” and checking “Use proxy for all results”.

Exporting Results

For power users, SearXNG can output results in machine-readable formats. Append ?format=json to your search URL (e.g., https://your-instance/search?q=privacy+tools&format=json). You will get a clean JSON response that you can parse with Python, JavaScript, or any programming language. This is excellent for building custom dashboards or monitoring tools.

Setting Up Shortcuts (Autocompletion)

You can create custom search shortcuts. For example, if you often search Wikipedia, you can set a shortcut like “w” so that typing “w quantum physics” directly searches Wikipedia. Go to Preferences > Shortcuts and add your own.

Tips for Getting the Most Out of SearXNG

1. Choose a Trustworthy Public Instance

Not all public instances are created equal. Look for instances that are run by known privacy advocates or organizations. Check if they have a clear privacy policy and whether they log data. The official SearXNG website lists instances with community ratings. Avoid instances that show ads or require registration.

2. Enable “Safe Search” for Family Use

If you are using SearXNG in a family environment, go to Preferences > General and set “Safe Search” to “Strict”. This filters out explicit content from most engines. You can also disable specific adult-oriented engines entirely.

3. Use the “Autocomplete” Feature Carefully

SearXNG can autocomplete your search queries, but this sends partial keystrokes to the backend engines. If you are extremely privacy-conscious, disable autocomplete in Preferences > General > “Autocomplete”.

4. Combine with a VPN for Double Privacy

While SearXNG hides your search from the engines, your ISP can still see that you are visiting a SearXNG instance. For maximum anonymity, use a VPN (like Mullvad or ProtonVPN) in conjunction with SearXNG. This encrypts your entire connection, making it nearly impossible to trace your searches back to you.

5. Regularly Update Your Self-Hosted Instance

If you self-host, keep your SearXNG container updated. Run sudo docker-compose pull && sudo docker-compose up -d periodically. This ensures you have the latest security patches and engine integrations.

6. Disable Unused Engines for Speed

By default, SearXNG queries many engines simultaneously. This can slow down results. Go to Preferences and disable engines you never use. For example, if you never search for torrents or files, turn off those categories. Fewer engines mean faster results.

7. Use the “Search Language” Setting

If you primarily search in English but occasionally need results in another language, set your default language in Preferences. This tells SearXNG to prioritize results from that language, which is especially useful for non-English speakers.

8. Bookmark Your Configured Instance

Once you have set up your preferences (engines, categories, themes), bookmark the instance URL. Your settings are stored in a cookie, so they will persist as long as you do not clear your browser cookies. For a more permanent setup, consider using a self-hosted instance where you can save settings to a file.

9. Explore the Theme Options

SearXNG comes with several themes (e.g., “Simple”, “Oscar”, “Dark”). Go to Preferences > Theme to choose one that is easy on your eyes. The “Dark” theme is excellent for nighttime browsing and saves battery on OLED screens.

10. Respect the Instance’s Resources

If you use a public instance, do not abuse it. Avoid sending automated queries (scraping) at high frequency. This can overload the server and ruin the experience for others. If you need to scrape, self-host your own instance.

Conclusion

SearXNG is more than just a search engine; it is a statement that privacy and functionality can coexist. By aggregating results from dozens of services without tracking you, it offers a powerful alternative to the data-hungry giants. Whether you choose a public instance or take the plunge into self-hosting, you are taking a meaningful step toward reclaiming your digital privacy. Start with a simple search, explore the settings, and gradually customize it to fit your workflow. The more you use SearXNG, the more you will appreciate its transparency and flexibility. Happy searching, and stay private!
