PandaStack documentation
Open-source Firecracker microVMs for AI agents — 240 ms cold starts, fork in milliseconds, run anywhere.
PandaStack is the open-source alternative to E2B. It gives your AI agent isolated Firecracker microVMs with sub-300 ms cold starts, mid-execution fork, and snapshot/restore in seconds — running on your own VPC, your own bare metal, or in our managed cloud.
What you'll find here
- Quickstart — Spin up your first sandbox in 30 seconds.
- Concepts — How sandboxes are born, forked, snapshotted, and torn down.
- SDKs — Python, TypeScript, and the
pandastackCLI. - Self-hosting — One-click deploy on GCP, AWS, Mac M1, or on-prem.
- Reference — REST + WebSocket APIs.
Why PandaStack
- Real isolation — Firecracker microVMs (KVM-backed), not containers.
- Fast — 240 ms cold boots from snapshot. ~50 ms fork. 5 ms file CoW via XFS reflink.
- Open source — Apache 2.0. Run it yourself. Audit every line.
- Multi-cloud — One-click deploy targeting GCP, AWS bare metal, or Lima on Apple Silicon.
