domains

# Custom domain with your own provider (/domains) Point a domain the user already owns at their Convex app. No purchase, no registrar credentials — you give the user the exact records to create themselves. ## Procedure 1. **Identify the target:** the published site host (for static hosting) or the deployment's HTTP actions URL (`npx convex env get CONVEX_SITE_URL` or the dashboard). 2. **Give the exact DNS records** to create at THEIR registrar: the CNAME (or A/ALIAS at the apex) plus the TXT verification record — concrete host/value strings, not placeholders. 3. **Attach the custom domain** on Convex (dashboard → deployment → Custom Domains, or the CLI) and wait for verification. DNS propagation can take minutes to hours — tell the user, don't poll forever. 4. **If the app uses auth** (passkeys/OAuth), rebind the auth origin (`SITE_URL` / `RP_ID` / `ORIGIN` env vars) to the new domain and re-deploy — otherwise sign-in breaks on the new domain. 5. **Verify:** the domain serves the app over HTTPS, including the apex → www redirect if configured. ## Rules - Never ask for registrar credentials — the user creates the records. - Always include the TXT verification record, not just the CNAME. - Rebinding the domain changes the auth origin — re-deploy after, or sign-in breaks.
