Vercel Sandbox
Execution SandboxProprietary · Proprietary (platform); @vercel/sandbox SDK is Apache-2.0★ 208（2026-10-04）Managed only
Ephemeral Firecracker microVMs on Vercel, one per sandbox.
Vercel Sandbox gives each sandbox its own Firecracker microVM with a dedicated kernel, filesystem and network, starting in milliseconds; it runs on the same Hive infrastructure that powers Vercel's 2M+ daily builds and defaults to a 5-minute timeout with Active CPU billing.
Caveat: Managed-only; the platform is proprietary (the @vercel/sandbox SDK is Apache-2.0).
