I was a paid Kagi subscriber. I unsubscribed due to my temporary financial difficulties, but I'm resubscribing as soon as I'm able to afford expenses like this. I'm VERY happy with them.
My major concern with kagi is that its good now, whos to say it will ne good in the future. Plenty of SAaS have ebshitiffied. We NEED open infrastructure fpr search. What that lools like Im not sure but it may be possible in the far future.
