Good to to a fellow FOSS fan!
Brave- good results and independent search index but the endless captchas made me homicidal.
startpage- results weren't quite up to par bit I liked the mission.
searx- Fantastic but I couldn't quite configure it right for my needs.
Right now I'm using Kagi and so far it's fantastic other than that you have to pay after 500 searches. But it's damn good and better than google for me.
Bing- Their chatgpt integration excites me but too early to tell.
