Summary
Vercel Sandbox now supports up to 10,000 concurrent sandboxes on Pro and Enterprise plans, up from 2,000, with per-minute vCPU allocation scaling automatically to 5,000. A dynamic quota starts at 150 vCPUs per minute and grows with sustained usage.
What changed
On August 5, 2026 Vercel increased Vercel Sandbox limits: concurrent sandboxes rose from 2,000 to 10,000, and per-minute vCPU allocation now scales up to 5,000 (from 200/min on Pro and 400/min on Enterprise) using a dynamic quota that begins at 150 vCPUs per minute.
Why it matters
Sandboxes are the isolated compute agents use to run untrusted code, tests, and builds. A 5x jump in concurrency plus far higher vCPU headroom lets teams fan out many agent or CI jobs in parallel without hitting ceilings, which matters as agentic workloads shift from single long tasks to large parallel batches.
Evidence excerpt
Concurrent sandboxes capacity was raised to 10,000, up from the previous 2,000.
