Cube Sandbox delivers sub‑60 ms AI agent sandboxes with <5 MB memory
Cube Sandbox, an open‑source service built on RustVMM and KVM, boots hardware‑isolated sandboxes for AI agents in under 60 ms using less than 5 MB of RAM. It works with the E2B SDK, supports single‑node and multi‑node clusters, and adds snapshot, auto‑pause and policy‑based egress controls.
