Convex Domains

If you already own a domain and want it pointing at a Convex app, this skill walks you through the whole thing: picking the target (the `*.convex.app` host or the deployment's HTTP actions URL), creating the DNS records, attaching the custom domain, and checking that it resolves over HTTPS. Where it earns its keep is the auth step. If your app uses passkeys or OAuth, changing the domain changes the origin, so SITE_URL, RP_ID, and ORIGIN all need rebinding and a re-publish, or sign-in quietly breaks. It can also drive your DNS provider's CLI directly (Cloudflare, Route53, gcloud, doctl, Vercel) if one is already logged in, showing each command for confirmation first. The one thing to watch is that it always adds the TXT verification record alongside the CNAME, and that's the record people most often forget.

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.
