You can now add any prefix before your preview deployment URL, and Vercel will route the request to the correct underlying preview deployment.
With dynamic prefixes appended before --- in a preview URL (like tenant-123---project-name-git-branch.yourdomain.dev), Vercel can now interpret those prefixes and route them to the correct deployment. Previously, preview URLs were designed to match a specific preview deployment exactly and Vercel wouldn’t have enough information to route domains to a specific preview deployment.
Now you can:
Create unique preview URLs for each tenant
Encode metadata, routing context, or automation signals directly in the URL
Use flexible URL structures such as:
tenant-123---project-name-git-branch.yourdomain.dev
Preview URLs for multi-tenant platforms are available for Pro and Enterprise teams, and require a Preview Deployment Suffix (a Pro add-on).
Try the demo or to get started, go to your team's settings to set your Preview Deployment Suffix. Then, follow our guide on configuring multi-tenant preview URLs.
