Details

Vercel Sandboxes has been officially launched, providing an ephemeral compute environment for safely running untrusted code.

Outputs generated by AI agents, unverified user-uploaded files, third-party code, and more can be executed safely without exposing production systems.

Each sandbox runs inside a Firecracker microVM, fully isolated from the infrastructure. As a result, code running inside the sandbox cannot access environment variables, database connections, or cloud resources.

Teams such as v0, Blackbox AI, and RooCode are currently using it in production, and developers can easily adopt it via the open-source SDK and CLI.
