Point a domain you already own at your Convex app (DNS records, custom-domain attach, auth-origin rebind).

<! GENERATED from convex agents content/capabilities/domains.json — do not edit by hand. Set up a custom domain with your own provider Walk the user's own registrar through pointing their domain at the Convex app: identify the target (hosting or deployment URL), create the DNS records, attach the custom domain, and rebind the auth origin if the app uses auth. Workflow 1. Identify the target: the published site host (for .convex.app static hosting) or the deployment's HTTP actions URL. 2. Detect an ALREADY AUTHENTICATED DNS CLI for the user's provider and OFFER to create the records automatically: Cloudflare → flarectl dns create (note: wrangler itself doesn't manage DNS records) or the CF API via their token env; Route53 → aws route53 change resource record sets ; Google Cloud DNS → gcloud dns record sets create ; DigitalOcean → doctl compute domain records create ; Vercel DNS → vercel dns add . Check auth read only first ( flarectl user info / aws sts get caller identity / doctl account get ); show the exact commands and get a yes before running. 3. If no authed CLI (or the user declines), tell the user exactly which records to create at THEIR registrar: the CNAME (or A/ALIAS at the apex) plus the TXT verification record — with concrete host/value strings, not placeholders. 4. Attach the domain as a Convex custom domain (dashboard or CLI) and wait for verification; note DNS propagation can take minutes to hours. Verify records landed with dig +short . 5. 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/re publish. 6. Verify: the domain serves the app over HTTPS, including the apex → www redirect if configured. Rules Never ask for or handle registrar credentials. A CLI already authenticated on the user's machine is fine — the credential stays in the tool; never install a CLI or run its login/auth flow for this, and never echo tokens. DNS changes on a live domain are user visible: show the exact commands and confirm before running them; verify afterwards with dig. Always include the TXT verification record, not just the CNAME. Rebinding the domain changes the auth origin — re publish after, or sign in breaks.
