Update Subdomains

In this guide, you'll learn how to update the Medusa-provided subdomains for your backend and storefront.

What are Subdomains?#

Each environment gets a backend subdomain under medusajs.app and a storefront subdomain under medusajs.site. You can update these subdomains from the environment's Domains settings page.

These are different from custom domains, which let you serve your backend and storefront from your own domain names.

Update Subdomains#

To update the backend or storefront subdomain:

1. In the environment's dashboard, click on the "Settings" tab.
2. Choose the "Domains" tab from the sidebar.
3. Under the Medusa-provided domains section:
   • To change the backend subdomain, update the value in the Backend subdomain field. The full URL will be https://<your-subdomain>.medusajs.app.
   • To change the storefront subdomain, update the value in the Storefront subdomain field. The full URL will be https://<your-subdomain>.medusajs.site.
4. Click Save changes.
