I should add a friend has recommended DNsimple.com and I’ve previously found their service to be excellent.
50 cents per domain per month 10 cents per million queries
That’s prob cheap enough to support lots of little hobby sites and bigger traffic sites likely have some budget.
Second DNSimple. Cheap to start and lots of nice features/support if you grow e.g. terraform provider, an acme.sh plugin, Okta support etc.
I used them in the past (many years ago) and was very surprised when my DNS was affected by a cloudflare outage. Turns out (back then) they relied on the cf network for DoS protection against their resolvers[1]. I was surprised to learn that and honestly thought that if I already take a dependency on cloudflare I might as well have them host my zones directly for free.
[1] Not completely sure but I think this was the incident https://blog.dnsimple.com/2020/07/incident-dns-resolution/
