Details

  • Vercel Project Connections allow applications to evaluate flags defined in another project within the same team without managing SDK keys.
  • Authentication relies on the deployment’s identity, replacing the previous method of copying server SDK keys into environment variables.
  • Connections grant read-only access across all environments, with the consumer deployment determining the specific flag environment evaluated.
  • The feature is available on all plans and requires @flags-sdk/vercel 1.6.0 or later, or @vercel/flags-core 1.11.0 or later when using the core library directly.
  • Access management is handled via the Connections page or the vercel flags connections CLI command, which requires Vercel CLI 63.0.0 or later.
  • Access can be revoked without redeploying the application.
