What Vercel is
Vercel Sandbox runs Firecracker microVMs on the same infrastructure as Vercel
Functions, exposed through an SDK meant to be called from a Vercel
app. The product has moved a long way from its ephemeral launch: sandboxes are now persistent by default, snapshotting their filesystem on stop and resuming from it, with an explicit fork call, custom images from Vercel
's container registry, and a per-sandbox egress firewall that takes a domain allowlist. Billing follows Vercel
's active-CPU model, which is unusually kind to agent workloads that spend most of their life waiting. The catch is placement: it runs in a single US region.
