Custom Domains

Wire your own domain to your deployed sandboxes (Pro plan).

Custom domains let you serve a deployed sandbox at a domain you own (acme.com, app.example.com). Available on the Pro plan.

Adding a custom domain

1

Open Account > Server > Domains

The current default domain is shown. Click Add custom domain.

2

Enter your domain

Enter the full host (app.example.com).

3

Verify ownership

The platform shows a verification record (TXT or CNAME). Add it at your registrar's DNS panel.

4

Wait for propagation

DNS changes typically propagate within minutes. The platform polls and confirms when verification succeeds.

5

Point your domain to your workstation

Add a CNAME record for your domain pointing to the value the platform provides.

After verification and DNS propagation, your domain serves your deployed sandbox.

Domains and TLS

The platform automatically issues and renews TLS certificates for verified domains. There is nothing you need to configure for HTTPS.

Domain to sandbox mapping

Each custom domain maps to one sandbox. Multiple custom domains can map to the same sandbox (for example, acme.com and www.acme.com). One custom domain cannot serve multiple sandboxes simultaneously.

Removing a domain

From the same Domains panel, click Remove next to the domain. The mapping is deleted; certificates are revoked and not renewed. DNS at your registrar is unchanged; you can repoint elsewhere.

Production restriction

Custom domains map to deployed sandboxes only, not to development previews. Preview URLs always use the platform-provided subdomain. This is a deliberate separation of dev and production traffic.
