Domains
Default subdomain
Section titled “Default subdomain”Each service is reachable at:
https://<your-subdomain>.runsite.appYou pick the subdomain when you create the service. If the name is taken, Runsite appends a short numeric suffix (e.g. my-api-2.runsite.app).
A few subdomains are reserved by the platform and can’t be used: docs, api, app, auth, status.
You can rename the subdomain later in Settings → Domain.
Custom domains
Section titled “Custom domains”Attach as many of your own domains as you like.
- Open Settings → Custom Domains and click Add Domain.
- Enter the domain (e.g.
app.example.com) — Runsite shows you the DNS records to add at your registrar. - The domain appears as Pending. Click Verify once DNS has propagated.
- Once verified, a TLS certificate is issued automatically. The status flips to Verified with a lock icon.
You can delete a custom domain at any time. For the full DNS walkthrough see Custom Domains.
