Custom domain

Two DNS records instead of a proxy, with certificates handled for you.

A custom domain serves the tag from a hostname you own — s.example.com — so it is first-party to a blocker, without you having to run and maintain a proxy path.

How it goes

  • Enter a subdomain of your own site under Site, then Settings, then Custom domain.
  • Add the two DNS records the page shows you: a CNAME pointing the subdomain at us, and a TXT record proving you control the name.
  • Click Verify. We resolve the TXT record; on a match the domain is marked verified.
  • The install snippet immediately switches to your hostname. Nothing else changes — data-domain stays your main domain.
CNAME  s.example.com                  ->  causalit.fr
TXT    _causalit-verify.s.example.com  ->  causalit-verify=<token>

Certificates

The certificate for your subdomain is issued automatically on its first HTTPS request. Only verified domains are authorised, so nobody can point a hostname at us and have a certificate minted for it.
