Deployments are now up to 7 seconds faster

Applies automatically to Git, dashboard, and CLI deploys; upgrading the CLI saves up to 2.1 seconds more.
Vercel has cut end-to-end deployment time by up to 7 seconds, with most of the savings coming from platform overhead that ran on every Vercel build regardless of project size.
The changes remove up to 5 seconds of fixed overhead automatically on builds triggered through Git, the dashboard, or the CLI:
- Internal build-process shutdown now happens outside the critical path to deployment readiness, saving about 2.2 seconds.
- The Vercel CLI is prepared ahead of time inside the secure, isolated build environment, saving about 930ms of startup work.
- Deployment finalization starts earlier, processing routing and output metadata concurrently with other work, saving about 413ms.
- Redundant API and storage requests are eliminated across build start and finalization, including fetching deployment configuration and loading build records directly by ID, saving about 900ms.
Deploying with the latest Vercel CLI saves up to another 2.1 seconds: the CLI now finishes as soon as the event stream reports domain aliases assigned instead of waiting for the next polling interval, resolves the deployment's team directly instead of loading the complete team list, and reuses deployment and project information it already has instead of making two extra API requests. Run vercel upgrade to get the latest CLI. The gains are most noticeable on smaller builds, where orchestration makes up a larger share of total build time.
