Domain Settings

Domain settings live in three places, depending on what you're configuring.

Workspace Domain

Configure under Settings → General → Workspace Domain.

Edit your subdomain name or set a custom domain for your workspace.

Customize Domain

1. Click Customize Domain
2. Edit your subdomain (e.g., yourcompany.twenty.com)
3. Or set up a custom domain (e.g., crm.yourcompany.com)

For custom domains, you'll need to configure DNS settings with your domain provider.

Approved Domains

Configure under Settings → Members → Access.

Anyone with an email address at these domains is allowed to sign up for this workspace automatically.

Add Approved Access Domain

1. Click Add Approved Access Domain
2. Enter your company domain (e.g., yourcompany.com)
3. Save

Once configured, anyone with an email address at that domain can join your workspace without needing a direct invitation.

<Note> This is useful for allowing your entire team to self-register while keeping the workspace restricted to your organization. </Note>

Public Domains

Configure under Settings → Apps → Developer.

Provision a complete and secure hosting environment on these domains. A public domain can be bound to a specific app — when bound, only that app's HTTP-routed logic functions are reachable on the domain. Leave the binding empty to expose all workspace HTTP routes.

Add Public Domain

1. Click Add Public Domain
2. Enter the domain you want to use
3. Optionally bind it to an app
4. Configure DNS settings as instructed
5. Verify the domain

SSL certificates are automatically provisioned for public domains.
