zeroboot is a Rust tool that provides sub-millisecond VM sandboxes for AI agents, using copy-on-write forking on top of KVM/Firecracker-style virtualization. The repository ships a zeroboot binary built with a Rust toolchain under an Apache-2.0 license.

Reach for it when AI agents need to execute code in isolated virtual machines with near-instant startup.

Use it to

Sandbox AI agent code execution
Spin up per-task isolated VMs quickly
Run untrusted code in isolated environments
Fork pre-configured VMs via copy-on-write

For Developers building AI agents that execute code
