--- title: "Now generally available: Automatic deploy subdomains | Netlify blog" description: "Choose a custom domain for your Deploy Previews and/or branch deploys. Netlify will automatically generate custom preview subdomains for you." source: "https://www.netlify.com/blog/automatic-deploy-subdomains-ga/" last_updated: "2026-08-05T03:10:29.000Z" --- 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. ![Deploy Previews and branch deploys are each set to use a custom subdomain](https://cdn.sanity.io/images/o0o2tn5x/production/6eec07a3ba17e8077d0b6c5fc1e80cee17c02eff-1918x806.webp) ## Why set a custom deploy subdomain? Automatic deploy subdomains enable you to: - Quickly spin up [additional environments](https://docs.netlify.com/site-deploys/overview/#branches-and-deploys) 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](https://www.netlify.com/blog/how-to-bring-a-subdomain-to-netlify-dns/), 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”. ![Both Deploy Previews and branch deploys can take a domain (selected from a dropdown) and an optional, additional subdomain prefix](https://cdn.sanity.io/images/o0o2tn5x/production/5af38c401c10e1766901ab864b8ba15bcdef14cc-1918x1346.png) 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: ![Hovering over a Deploy Preview link on the Netlify UI shows a custom URL in place of the netlify.app URL](https://cdn.sanity.io/images/o0o2tn5x/production/c475bc9b11b35ff030cdcee91b2f6eacb24f4f38-1512x644.webp) ## Try it out today You can learn more about how automatic deploy subdomains work and interact with other features [on the docs](https://docs.netlify.com/domains-https/custom-domains/automatic-deploy-subdomains/).
