New Domains tab in the Workers dashboard
In your Worker's dashboard, there is now a dedicated Domains tab where you can purchase a new domain through Cloudflare Registrar and have it automatically connected, add an existing domain, and manage all of your Worker's routing in one place.

You can also enable or disable your workers.dev subdomain and Preview URLs, put them behind Cloudflare Access to require sign-in, and jump directly to analytics or domain overview for any connected domain.
To get started, go to Workers & Pages, select a Worker, and open the Domains tab.
