Vercel Flags now supports progressive rollouts, letting teams automatically shift traffic to a new feature variant on a schedule instead of holding a fixed split.
The difference from weighted experiments matters: each rollout stage defines a target percentage and a duration, so a bad deploy hits 5% of users before it hits 100%. That staged exposure is the core safety mechanism worth understanding in detail.
Access is live now via the Vercel dashboard and the new `vercel flags rollout` CLI command. The full mechanics of stage configuration and regression detection are in the Vercel Flags documentation.
