New Vercel Flags projects no longer need SDK Keys

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

Read the Vercel Flags documentation to get started.
