I really like Kagi. The only thing bugging me is there is occasional delays when searching, at least from the UK. Google's instant search definitely has spoiled me there.
Reporting these when they happen to kagifeedback.org will go a long way (screenshot of page with inspector in browser open). We do not run any client side telemetry so we can not be proactive about this - need reports from users!
I remember trialing it a while back and gave up pretty fast due to the consistent very long delays when searching from Ireland.
Yeah, I wonder if it's optimized for US only right now. If the Kagi team is listening, please fix for world wide :). It's not always bad, but P95 needs work.
