Vercel Sandbox now supports 10,000 concurrent sandboxes and 5,000 vCPUs per minute
↗
Vercel increased default quotas for Sandbox on Pro and Enterprise plans, raising concurrent sandbox limit from 2,000 to 10,000 and introducing a dynamic vCPU allocation rate that can reach up to 5,000 per minute.
For engineers using Vercel Sandbox for testing or development, this change removes a hard ceiling on parallel workloads, allowing larger-scale simulations and faster iteration. However, the dynamic vCPU rate means burst capacity is not instantly available, it ramps from 150 vCPUs per minute, so short-lived spikes may still be throttled. Teams that need sustained high throughput must plan for the ramp-up period or contact sales for custom limits.

Concurrent sandbox limit increased from 2,000 to 10,000 for Pro and Enterprise plans.
vCPU allocation rate is now dynamic, starting at 150 per minute and ramping by 500 per minute up to 5,000 per minute.
The new quotas apply automatically; higher limits require contacting Vercel sales.
