I was just checking them out as a possible place to move my DNS names to. Looks like it's a whopping $0.50/month if you use their nameservers per address, plus $0.40 per million queries, prorated, So probably tough to spend more than $1 a month on without having Google-scale and spending way more than that on servers.

They do the latter, it's $0.40 per million queries.

(And since the records are size-limited, per-GB is roughly the same thing.)

"Except for Alias A/AAAA records mapped to AWS services listed below, you incur charges for every DNS query answered by the Route 53 service."

Yeah me too - they charge for name servers but I figured out after a while that Linode did the same thing for none of the cost.

But for domain registrations alone it's fine.

Cloudflare requires you use their name servers
