SearXNG instances, bravesearch, startpage, etc...

https://leta.mullvad.net/ uses Brave or Google

https://searx.space/ uses any of the big search engines you want, you do have to pick an instance

Yacy? You can self host if you want.

Best one is probably (in my opinion) selfhosting a searxng instance. It takes results from a dozen of engines (you configure which ones) and merges them according to the configured weights and some algorithmic magic.

If you use public instances, the owner might have tuned the results to suit themselves and it returns garbage for your usecase. And also they frequently get timeouts because a lot of people use them. So don't get turned off by trying a couple of them.

Since I started running my own private instance I am super happy with the search results.

Kagi. Privacy focussed, no ads, and excellent results with options for sorting preferred sources to appear at the top, or not. Costs money but man, it’s fast and good in the way Google was back in the day. Some plans also include anonymous access to a variety of LLMs though they are older models, and if they can run them locally, they do. Really liking it.

Startpage is similarly anonymous, but it uses Google search

searxng and 4get are great alternatives
