workers.dev
Cloudflare Workers accounts come with a workers.dev subdomain that is configurable in the Cloudflare dashboard. Your workers.dev subdomain allows you to deploy Workers without attaching your domain as a Cloudflare zone.
The first time you visit the Workers & Pages in the Cloudflare dashboard, a workers.dev subdomain is automatically assigned to your account.
To change the name of your workers.dev account subdomain, such as <YOUR_ACCOUNT_SUBDOMAIN>.workers.dev:
- Log in to the Cloudflare dashboard and select your account.
- Select Workers & Pages.
- Select Change next to Your subdomain.
All Workers are assigned a workers.dev route when they are created or renamed following the syntax <YOUR_WORKER_NAME>.<YOUR_SUBDOMAIN>.workers.dev.. The name field in your Worker configuration is used as the subdomain for the deployed Worker, (for example, <YOUR_WORKER_NAME>.<YOUR_SUBDOMAIN>.workers.dev.).
