Good things: unlike DDG or MetaGer, zero tracking. zero ads. Clean. Unlike SearXNG, you’re not using Github (a good move). This might become huge. The fact that it’s not perfect now, doesn’t matter.
Bad things: Obviously it’ll be hard to be better than SearXNG. A donation link is especially bad; ko-fi.com itself can be there, but… In the donation campaign, SearXNG accepted crypto, while you’re only using a Paypal-like thing. That’s not really cool.
