If it works for you… I agree with the general sentiment of “if its free you are the product”. However, I see kagi come up so often around here that I feel like it’s some astro turfing. I tried it and was not impressed. SearXNG is by far the best search engine I’ve used in a long time and the best part is I am hosting it locally on my PC, traffic is going out a VPN. You get the privacy and the best results possible since its a meta engine using many different engines.
