BoxLite

One micro-VM runtime — embed it, run it, deploy it, distribute it.

BoxLite is a micro-VM runtime in Rust. It spins up lightweight, stateful Boxes — OCI containers each running in their own Linux kernel — so AI agents get real isolation, from your laptop to serverless scale.

• Embed — in-process library; ship sandboxing as a feature.
• Run - all-in-one CLI, no daemon required, zero deployment
• Deploy — standalone server for multi-tenant workloads.
• Distribute — cluster it for serverless-scale execution.

Small as a library, elastic as a service — one repo, sub-50ms boot.

Embed it — sandboxing as a library

pip install boxlite

import asyncio
import boxlite

async def main():
    async with boxlite.SimpleBox(image="python:slim") as box:
        result = await box.exec("python", "-c", "print('Hello from BoxLite!')")
        print(result.stdout)

asyncio.run(main())

Run it — the binary, one command, no daemon

curl -fsSL https://sh.boxlite.ai | sh
boxlite run python:slim python -c "print('Hello from BoxLite!')"

Deploy it — a standalone server

boxlite serve 

Distribute it — serverless scale

git clone https://github.com/boxlite-ai/boxlite && cd boxlite/apps/infra
npx sst deploy --stage production

• Stateful — environments persist across sessions; install once, resume later.
• Reversible — checkpoint, roll back instantly, fork for parallel exploration.
• Isolated — every box runs its own Linux kernel in a micro-VM (KVM / Hypervisor.framework).
• Fast — sub-50ms boot, not minutes.
