Vercel Sandbox expands from four regions to twenty

Vercel made Sandbox available in all 20 compute regions on September 10, 2026, up from four. Region selection is available on every plan; Pro and Enterprise teams can configure failover regions, which Vercel tries in order when a sandbox cannot be created in the primary. The default remains iad1 and pricing varies by region.

Why it matters

A sandbox that runs far from the database it queries pays for that distance on every call. Putting execution next to state is the cheapest latency win available here, and it was not previously possible outside four regions.

Who should care

Teams running untrusted or generated code on Vercel

What you can do

Set the sandbox region to match wherever your database lives rather than leaving it on iad1, and check the per-region price before moving.
