Kagi is worth every penny. Been using it for 6 months as my primary search engine. I think I have used the Google !g 10 or so times in that period maybe?
Plus, Searx supports many more search engines, and I can customize it exactly to my liking.
I wish them well, as they clearly have good intentions and a good product, but I prefer using an equivalent OSS and self-hosted solution over a proprietary SaaS I have to create an account for, even if it's not as polished or featureful.
EDIT: Actually, I'm wrong. Kagi apparently also has their own crawlers and indexes[1]. Still, I'm not finding Searx results to be deficient, so I'm not missing out on much.
One thing that does concern me with Searx, and partially with Kagi, is that those 3rd parties could decide to block these API requests at any point, leaving Searx unusable, and Kagi's results less relevant. I'm not sure this is a sustainable way to build a search engine, but I do appreciate both Kagi's and Searx's stance on ads. Using any mainstream search engine via their own frontends is a frustrating experience at best.
