Vercel Deploy

Ship a Next.js app to Vercel and control its environments safely: preview deploys for review, production promotes behind confirmation, and a fast rollback when a deploy goes bad. Deploying is publishing — every production action is gated.

Contract

Inputs:

• A linked Vercel project; mode preview (default), prod, rollback, or env.

Outputs:

• A deployment URL (preview or production), or the restored deployment (rollback), or the env-var change summary.
