What it does
When an AI agent writes and runs code, it is safer to keep that code away from your real systems. Cube Sandbox creates a "sandbox", a small walled-off virtual computer, for each task. Its makers say each one starts in well under a second and has its own operating system core for strong separation.
It can run on one server or across many, and many sandboxes can share a machine. It also supports snapshots, so a sandbox can be saved, copied or rolled back. It is built to work with the same programming interface as E2B, another sandbox service.
Who it's for
Engineering teams that run AI agents at scale and need a safe place for those agents to execute code.
