Summary
In its September 10-11, 2026 changelog, Vercel expanded Vercel Sandbox, its isolated environment for running untrusted or agent-generated code, to all compute regions with per-sandbox region selection, and doubled default storage from 32 GB to 64 GB per sandbox.
What changed
Vercel Sandbox is now available across all Vercel compute regions, with per-sandbox region selection and regional failover options (September 10). Default storage per sandbox increased from 32 GB to 64 GB (September 11).
Why it matters
Broader regional coverage and larger per-sandbox storage make Vercel Sandbox more viable as the execution substrate for AI agents and CI-style workloads that need data locality, lower latency, and room for larger repositories or build artifacts. It strengthens Vercel's position in the increasingly crowded agent-sandbox layer.
