Vercel Flags no longer requires SDK Keys for Vercel deployments
Mirrored from Vercel — AI for archival readability. Support the source by reading on the original site.
New projects using Vercel Flags no longer need to configure SDK Keys or the FLAGS environment variable when evaluating flags inside a Vercel deployment. At runtime, the Vercel adapter automatically receives a short-lived OIDC token, so authentication is handled for you with zero configuration.
For local development, link your project with vercel link and pull credentials with vercel env pull. That's it.
Existing projects and all SDK Keys are unaffected. This change only applies to new projects, and SDK Keys remain fully supported and are still required for:
Cross-project flag access
Non-Vercel runtimes
Custom authentication setups
Key rotation workflows
