Hey Product Hunt 👋 I'm Arpan, building StacyOS with a small team. What we're shipping today StacyVM v1.0 — self-hosted sandbox infrastructure for AI agent execution. It's the first piece of a bigger project (StacyOS), but it's a real product on its own. If you've been building AI agents and you've felt the weirdness of routing every piece of agent execution through someone else's cloud, this is for you. The problem that drove us here Every coding agent, every AI workflow, every "vibe-coded" app eventually needs to run somewhere safe. Today the default answer is a managed cloud sandbox — E2B, Daytona, Modal. They're great products. But three things kept bothering us: (1) Your code, your data, your execution all leave your boundary. (2) There's no signed attestation of which worker did what — if you need to audit "who ran this," the answer is usually a chat log. (3) You're locked into one provider's runtime, pricing model, and uptime. StacyVM is the self-hosted alternative. Multi-provider runtime (Firecracker for production, Docker for local, gVisor and PRoot for restricted hosts) behind one stable API. Signed worker identity with HMAC-SHA256 tokens, audience separation, emergency revocation. OIDC/SSO, RBAC, tenant audit export, mTLS for worker RPC. Live preview URLs. REST API plus Python and TypeScript SDKs. Phase 14 just shipped — the hardening release that makes it production-grade. How to try it (60 seconds) npx stacyvm-setup@latest That installs the control plane and gets a sandbox running locally. From there: pythonfrom stacyvm import Client c = Client("http://localhost:7423") s = c.spawn(image="python:3.12") print(s.exec("python -c 'print(40+2)'").stdout) Docs: https://docs.stacyos.xyz · Repo: https://github.com/StacyOS/stacyvm Where this is going StacyVM is the execution layer of a larger project. The full StacyOS has four layers — execution (StacyVM, shipped), coordination (Stacy Sync, three published research papers, federation primitive in ~90 days), memory (Stacy Brain, roadmap), and a sovereignty layer that wraps the rest. The thesis: the agent economy is being built layer-by-layer, and the substrate underneath those layers doesn't exist yet. StacyVM is the first piece of that substrate shipping. If you're building an AI agent, a coding assistant, a workflow tool, or anything that needs sandboxed execution with real audit — please install it and break things. We have 5 design partner slots open for Q3 if any of you are taking this into production. DMs open here and on X (@stacyos). Open source, Apache-2.0-licensed. Three research papers on ResearchGate if you want to go deep on the architecture. Happy to answer anything in the comments today. Thanks for taking a look 🙏
