Don’t keep your laptop open. Opensource agent workspace that deploys microVMs.

Open sourcing what I’ve been building. Krowoc gives an agent a real machine — shell, filesystem, headless Chrome — in its own micro-VM. Close the tab, close the laptop. Long tasks keep running and scheduled jobs fire on their own. Models: open weights through Fireworks (Kimi, GLM 5.2, DeepSeek V4, MiniMax M3), or bring your own key — Anthropic, OpenAI, OpenRouter, local Ollama, any OpenAI-compatible endpoint. No proxy in the middle, nothing marked up. Why micro-VMs An agent holding shell access and your MCP tokens is the highest-trust software you’ll run. On a shared container, one prompt injection off a browsed page reaches every other tenant’s keys and files. Full VMs fix the blast radius but are too slow and expensive to hand one to every user. Micro-VMs boot in ms with hardware-level isolation — VM-grade separation at roughly container cost. That’s the only reason per-user isolation is affordable here at all. It’s also what makes the close-your-laptop part real. The environment is durable infrastructure, not a session. Cron on your own machine dies when the lid shuts. Why BYO key and open source Same reasoning. Something holding your shell, your files, and your Gmail and Notion tokens should be code you can read, running where you choose. No proxy means your keys never touch my server — self-host and they never leave your box. Apache 2.0. Self-host it, or use the hosted instance. krowoc.com github.com/nikonr7/krowoc Rough edges: no Bedrock/Vertex auth yet, scheduled triggers are the newest piece, solo maintainer.
