Host your own non-tracking search engine with searx
It is not a secret that most search engines like Google, Bing or Yahoo track search habits and sell your personal data to third parties in the form of ads. Wouldn't it be a great if one could use search engine that is free of such pervert practices? Surely, you could use DuckDuckGo, WolframAlpha or Startpage but this will give you less and limited variety of content than mainstream search engines. After all it is their business model and they invest a lot of money to index internet for which you indirectly pay by being exposed to ads.
To the rescue comes Searx a metasearch engine that aggregates results from more than 70 search services without tracking and giving your direct links to the content. The best part is that you can run it yourself locally, in the cloud or on VPS.
