What runs here

Every surface this domain backs. DNS answers, certificates and routing all come from selfhost — no registrar console, no third party.

3 public surfaces ✓ the software behind it

hostkindwhat it is
rockywearsahat.com ● static this site — built by Astro, served by selfhost’s own HTTP stack — the page you are reading
mail (mx) ● app selfhost’s own SMTP / IMAP / DKIM implementation — alex@rockywearsahat.com terminates here
helpers.rockywearsahat.com ● redirect https://github.com/RockyWearsAHat/helpers — project home until it earns a real page

Adding a service to the internet, forever, is one entry in the registry and one selfhost site add — DNS and the certificate are automatic, because the machine answers its own DNS and orders its own certificates.
