I mean, it's something I'd consider. I have a little ARM SBC here that I run Plex and Immich etc on. But Kagi makes it very easy for a not terrible price -- not much more than the monthly power bill for a little server -- and they also do more than just grab from other search services as they _do_ have their own crawler (unclear how much it's used for results?) and have LLM stuff which isn't terrible.

Also as a former Google employee... I dig the idea of contributing funds for some competition in this space.
