I didn't look too hard but didn't see any similar free services with full DNS management and an API for cache validation. Would love a suggestion here too!

Why not just pay for something like Route53? It's very cheap.

Isn't that an AWS thing?

AWS? Cheap? Really?

[technion]

Route53 might as well be free. Yes it's AWS, but it's costing me less than a dollar a month on a domain that has trended here several times.

[artursapek]

AWS isn't cheap or expensive. It's a bundle of services and you're free to use any combination of them. Route53 can be used independently and yes it's very cheap.

I use Route 53 myself and it's under $3 for several domains. Google Cloud DNS is even cheaper.
