Vercel Sandboxes are now generally available
By Steven Van ·
Vercel Sandbox, its isolated microVM for running untrusted or AI-generated code, is now generally available.
Vercel Sandbox is now generally available, giving developers an ephemeral compute primitive for running untrusted code without exposing production systems. Teams can use it to execute AI agent-generated outputs, unverified user uploads, and third-party code in isolation.
Each sandbox runs inside a Firecracker microVM, isolated from the rest of a team's infrastructure, so code inside a sandbox cannot reach environment variables, database connections, or cloud resources. A sandbox can be created with a few lines of the @vercel/sandbox package, or started from the command line with npx sandbox create --connect for an interactive shell.
Vercel says sandboxes are already in production use by teams including v0, Blackbox AI, and RooCode. Read the full announcement for setup details.
