I've coerced Codex and Claude to build Cloudflare-but-shit because I wanted to have healthcheck-based DNS records (A, CNAME) so I can host stuff on 100 RPis in 100 different places with any type of connection (public IP or behind a CGNAT).
It has DDNS, Tunnels, very-flexible-record definition and Anubis will be implemented soon or you can bring your own.
Powered by PowerDNS and Rails, and if I get some free time I'd like to just have this as an actual offering since I always fear Cloudflare putting more and more things behind a paywall.
Shockingly, it works, obviously the DNS I'm doing now isn't RFC compliant, but this already scratches my itch.
