Every AI agent needs a safe computer. Most rent it from someone else's cloud. StacyVM is self-hosted sandbox infrastructure for AI-generated code — Firecracker, Docker, gVisor, and PRoot behind one API. Signed worker identity, live preview URLs, REST + Python + TypeScript SDKs. Production-ready at Phase 14. One install: npx stacyvm-setup@latest. The first piece of StacyOS — the operating system the agent economy assumes already exists.
