- SearXNG is an open-source metasearch engine that protects privacy by acting as a proxy between the user and search engines.
- It allows multiple installation methods, from using public instances to self-hosting using Docker or LXC containers in Proxmox.
- The community has developed extensions to filter SEO content and create custom search engines based on JSON APIs.
Have you ever felt like the internet is a fishbowl where someone is watching your every move? It's that annoying feeling of searching for something silly about vegan food and then, suddenly, all the ads of your life They fill up on tofu and plant-based milks. Well, this is where it comes in. SearXNG, a tool that comes to break those chains of surveillance and give us back control of our privacy while browsing.
Basically, we're talking about an open-source metasearch engine that doesn't store any of your information. Unlike giants like Google or Bing, which create a detailed profile of who you are and what you like, SearXNG acts as a protective shieldIt doesn't track you, it doesn't profile you, and above all, it doesn't sell your data to the highest bidder, allowing you to explore the web without being chased by phantom ads everywhere.
What on earth is a metasearch engine and how does it work?
For those who aren't very familiar with the topic, a metasearch engine isn't a traditional search engine with its own database. Think of it as a results aggregatorIt's like an all-you-can-eat buffet of information. SearXNG sends your query to multiple sources simultaneously (like Reddit, Wikipedia, Google, or DuckDuckGo), gathers the best from each, mixes it, and presents it to you on a single page, but without the original search engines knowing who you are.
This process is achieved through a system of reverse proxyThis means that SearXNG gets in the way of you and the final search engine. So, the original source sees the request from the SearXNG server, but It never finds out your IP address. nor your browsing history. Furthermore, it blocks by default any cookies that attempt to track you, thus eliminating the infamous "filter bubbles" that cause Google to only show you what it thinks you want to see.
Deployment options: How to implement it?
The great thing about this project is that it's extremely flexible. If you don't want to complicate things, you can look for a public instance It's already set up and ready to use right away. However, for those seeking the highest level of privacy, self-hosting is ideal, allowing you to set up your own server at home.
- Installation using Docker: It's the preferred option for many. A file is used.
docker-composeThis runs the SearXNG service along with Redis (for caching) and Caddy (for managing the web server and TLS). It's a clean way to run it in an isolated container. - Deployment on Proxmox: For homelab enthusiasts, there are community helper scripts which allow you to install SearXNG in an LXC container with a single command line, greatly simplifying resource management.
- Manual installation: It is also possible to install it directly on Linux distributions such as Debian, Arch or Fedora by following the official documentation.
If you're a complete beginner, don't panic. You don't need to be a hacker in sunglasses. Although hosting it on your PC means having Docker running and consuming some resources, the advantage is that You have total control from your search tool.
Advanced tricks and community extensions
The SearXNG community is very active and has created tools to take the search engine to the next level. For example, there are developments that allow filter AI and SEO resultsextracting content scores so you only see what's relevant. Some of these tools even allow you to export the data to a Language Model (LLM) to summarize the information or easily explore it using editors like nvim.
There are even those who have created custom enginesOne example is the integration of script catalogs for Proxmox, where you can directly search the JSON API of external repositories to find pre-built LXC containers without having to manually navigate through web pages. This demonstrates that SearXNG is a foundation upon which to build. productivity tools brutal.
Possible obstacles and solutions
It's not all sunshine and roses; when trying to use SearXNG for massive data scraping, it's common to hit a wall. Search engines like Google, Brave DuckDuckGo and others have very aggressive anti-bot systems and can lock your instance if they detect too many consecutive requests. Although using Tor proxies can help, sometimes it's not enough.
Another common problem arises when connecting SearXNG with AI interfaces like OpenWebUI. Some users report that, despite correctly configuring the JSON format and categories, the returned results are irrelevant or focus solely on dictionaries and wikis. In these cases, it is vital to check that the engine configuration in the file settings.yml is adequate and that the Docker network allows for smooth communication between containers.
This tool represents the ideal alternative for those who want to avoid digital surveillance, allowing you to add sources like Reddit and Wikipedia to a single, clean, ad-free, and completely private interface. Whether installed on your own server or using a public instance, SearXNG transforms the web into a more objective and less intrusive place, giving users back the ability to... discover real information without algorithmic bias or invisible trackers.
