Custom domains

Pro can serve a published app on your own domain (for example app.example.com) instead of only a *.mythex.ai link. Free plans publish to a Mythex subdomain only.

​
Buy a domain (Pro)

From Domains (/settings/domains) — same idea as Lovable workspace domains:
  1. Click Buy new domain
  2. Search for a name, pick an available result, optionally choose a project to connect
  3. Check out (Stripe) — Mythex registers the domain
You can also buy from Publish → Custom domain → Buy domain on a live project (auto-connects to that project). Bought domains are billed separately from your Pro plan. Manage auto-renew, reconnect, or transfer out on the Domains page.

​
Connect a domain you already own

  1. Publish the project
  2. Open Publish → Custom domain → Connect existing
  3. Enter your hostname (e.g. app.example.com)
  4. At your DNS provider, create a CNAME from that hostname to the target Mythex shows (usually {slug}.mythex.ai)
  5. Click Verify in Publish
When DNS is ready, the domain status becomes active. HTTPS uses Cloudflare (Custom Hostnames for BYO domains).

​
Requirements

  • Pro plan
  • Project published and live (to serve traffic on the domain)
  • For connect-existing: ability to edit DNS for your domain

​
Troubleshooting

  • DNS not ready — CNAME propagation can take a few minutes. Recheck Verify.
  • Wrong target — the CNAME must match the target shown in Publish for this app’s slug.
  • Still on Free — upgrade to Pro, then buy or add the domain again.
  • Transfer out — from Domains settings; copy the auth code into your new registrar.
