SearXNG[1] is a free and open-source metasearch engine that aggregates results from more than 70 search services, while protecting user privacy. It allows users to search the web without being tracked or profiled.

Key benefits of SearXNG include its self-hosting option and compatibility with the Tor network, allowing for further anonymity.

Installation

Configuration

Basic

services.searx = {
  enable = true;
  redisCreateLocally = true;
  settings.server = {
    bind_address = "::1";
    # port = yourPort;
    # secret_key = "Your secret key.";
  };
};

Advanced

services.searx = {
  enable = false;
  redisCreateLocally = true;

  # Rate limiting
  limiterSettings = {
