Never heard of them, but just looking at a registrar comparison chart, their renewal costs are pretty high. eg. $20 for .wiki renewal at Porkbun and $30 at Hover. Maybe they bundle in a lot of services along with it that make the price worth it? but unless you’re taking full advantage of those (if they’re offered) then you could def get a better deal elsewhere.

I just transferred all my domains out of Namecheap into Porkbun. I think Porkbun is 10 to 50 cents more expensive than Cloudflare, but they seemed a bit easier to use and could hold all my TLDs. So far, a way better experience than Namecheap!
