Vercel Sandbox increases concurrency and port limits
By Steven Van ·
Pro and Enterprise teams can now run up to 2,000 concurrent Sandboxes, up from 150, with each exposing up to 4 ports for external access.
Vercel raised the default Sandbox quotas for Pro and Enterprise teams: concurrent sandboxes jump from 150 to 2,000, and each sandbox can now expose up to 4 ports for external access.
The extra ports let a single sandbox run multiple services or protocols side by side. The higher concurrency limit supports larger traffic spikes for workloads like untrusted code execution, batch jobs, and automated testing. Teams that need more than 2,000 concurrent sandboxes at once can contact Vercel's sales team to explore higher limits.
