Limiting On-Demand Concurrent Builds to 1 per Branch

·2026.01.09 22:00

Key point

Vercel introduced a feature that limits on-demand concurrent builds to 1 per branch for the same branch and skips previously queued builds.

Details

Vercel's On-Demand Concurrent Builds feature allows builds to start immediately without waiting for other deployments to finish.

You can now configure this feature to limit active builds to 1 per branch. Deployments to the same branch will be queued, and once the active build finishes, only the most recent deployment will start, while earlier queued deployments are automatically skipped. However, builds across different branches can still run concurrently.
