Now generally available: Automatic deploy subdomains

Automatic deploy subdomains are now generally available for all Netlify customers with a Pro plan or above! You can set a custom domain for your Deploy Previews and/or branch deploys, and Netlify will automatically generate and link to these URLs for these deploy contexts.

Why set a custom deploy subdomain?

Automatic deploy subdomains enable you to:

• Quickly spin up additional environments at automatically-generated URLs.

• Share Deploy Preview links with stakeholders or clients, and help ensure brand safety of those previews.

• Help to ensure third-party integrations work properly in preview environments.

  For example: If your auth or database solution requires access from allow-listed domains, you can add *.previews.yourcompany.com to the allow list, instead of *.netlify.app.

• Empower security and IT teams to more easily build policies around company-controlled domains.

Set up in 60 seconds

Automatic deploy subdomains requires:

• That your production site has at least one custom domain

• A Netlify DNS-managed (sub)domain

  Note: We understand that not all apex domains can be delegated to Netlify DNS, so we recently added the ability to bring just a subdomain, at any domain level of your choosing.

To set up your subdomains at Site Settings > Domain Management > Automatic deploy subdomains:

1. Select “Edit custom domains”.
2. Check “Add domain” next to each deploy context you want to customize.
3. Select any domain from the “Domain” field. This list includes any (sub)domains you have delegated to Netlify DNS; you can add more at Team Overview > Domains.
4. Add an optional prefix in the “Additional subdomain” field. You can have deploys available at *.internal.yourcompany.com or *.qa.platform.yourcompany.com instead of *.yourcompany.com. There is no need to set up any additional DNS records for this.
5. Press “Save”.

Netlify will automatically generate wildcard DNS records and SSL certificates for each Deploy Preview (deploy-preview–123.internal.yourcompany.com) and deployed branch (branch-name.internal.yourcompany.com). We will use these URLs on the app, in the API, and in deploy notifications:
