SearXNG
docs.searxng.org ↗SearXNG is a free, open-source metasearch engine: it sends your query to other search services and merges the results.
Why it’s listed
It suits people who want search without a profile, and anyone happy to self-host or pick a public instance from searx.space.
It's listed because users are 'neither tracked nor profiled' and it can draw on up to 261 services1. The code is AGPL-3.0 and was updated today2. It's the maintained fork of Searx, whose maintainer has moved on3.
The trade-off
On a public instance you're trusting whoever runs it, and the results still come from engines like Google and Bing.
