Domains

Default subdomain

Each static site is reachable at:

https://<your-subdomain>.runsite.site

You pick the subdomain when you create the site. If the name is taken, Runsite appends a short numeric suffix (e.g. my-site-2.runsite.site).

A few subdomains are reserved by the platform and can’t be used: docs, api, app, auth, status, cdn.

You can rename the subdomain later in Settings → Domain.

Custom domains

Attach as many of your own domains as you like.

1. Open Settings → Custom Domains and click Add Domain.
2. Enter the domain (e.g. www.example.com) — Runsite shows you the DNS records to add at your registrar.
3. The domain appears as Pending. Click Verify once DNS has propagated.
4. 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.
