Kagi is brilliant. I find the whole Yandex -thing silly (EU spending on liquefied gas etc. from Russia is more than Yandex’s whole annual revenue) and only wish same scrutiny would be put on corporations funding Israel genocides.
I use DDG at work on Firefox with all AI blocked. If I would apart from Kagi, I would use SearXNG locally accessing it elsewhere with Tailscale. I think Hister seems promising, but have not tried it myself yet.
