Vercel

you.runs-on.dev serving a Vercel project, over HTTPS, via CNAME.

The record

domains/you.json

"records": { "CNAME": "cname.vercel-dns.com" }

cname.vercel-dns.com is the fixed target Vercel uses for every custom domain, not something specific to your project.

Steps

  1. Fork the registry and edit domains/you.json to the record above.
  2. Open a pull request. Once merged, the CNAME is synced to DNS automatically.
  3. In the Vercel dashboard: your project → Settings → Domains → add you.runs-on.dev. Vercel shows this exact cname.vercel-dns.com target when it asks you to configure DNS, confirming there is nothing else to add.

How to tell it worked

The Domains tab in Vercel shows a green "Valid Configuration" once DNS has propagated and the certificate is issued, usually within a few minutes of the pull request merging. Visiting https://you.runs-on.dev should then serve your project.
