Vercel Flags no longer requires SDK Keys for Vercel deployments
By Steven Van ·
New Vercel projects authenticate Flags automatically via OIDC, skipping SDK Keys, while existing projects keep working as before.
New Vercel projects using Vercel Flags no longer need to set up SDK Keys or a FLAGS environment variable to evaluate flags inside a Vercel deployment. The Vercel adapter now receives a short-lived OIDC token automatically at runtime, so authentication needs no configuration. For local development, linking the project with vercel link and pulling credentials with vercel env pull is enough.
Existing projects and all current SDK Keys are unaffected, and the change applies only to new projects. SDK Keys are still required for cross-project flag access, non-Vercel runtimes, and custom authentication setups. Read the announcement for details.
