Open source tools
for AI agents
Ghost OS gives AI agents eyes and hands. Shadow gives them memory. Specter gives them a home. Three products, each the first of its kind.
Ghost OS
1,200+ starsFull computer-use for AI agents. Your AI agent can write code, run tests, search files. But it can't click a button, send an email, or fill out a form. Ghost OS changes that.
Sending an email and downloading papers, all from a single prompt.
Accessibility tree, not screenshots
Reads structured data from every macOS app. Knows what's a button, what's a text field, what's a link. 100x faster than vision models.
Self-learning recipes
Show the agent how to do something once, it remembers forever. A frontier model figures out the workflow. A small model runs it from then on.
Any app, not just browsers
Slack, Finder, Messages, System Settings, Xcode. Anything on your Mac with an accessibility tree. Cross-app workflows just work.
29 MCP tools
Click, type, scroll, hover, drag, press keys, manage windows, wait for conditions, run recipes, learn workflows. Works with any MCP client.

v0.1.0Deploy AI agents to dedicated VMs in 90 seconds. Interactive TUI. Automatic DNS and TLS. You own the infrastructure.
Watch: deploying two agents from scratch
90-second deploys
From golden snapshot to running agent with DNS and TLS. No Docker builds at deploy time.
Interactive TUI
Lazydocker-style dashboard. Deploy, SSH, logs, destroy. All from keyboard shortcuts.
Automatic infrastructure
DNS via Cloudflare. TLS via Let's Encrypt. Systemd hardening. Dual firewalls. All automatic.
You own everything
Your Hetzner account. Your Cloudflare domain. Your SSH keys. VMs start at $3.49/month.
The complete stack for
autonomous AI agents
Every AI agent needs to see and act, remember context, and run somewhere persistent. Three products, three problems solved, one open source studio.
Imagine deploying an agent on Specter that has Ghost OS for computer-use and Shadow for context. An agent that knows your workflow, can operate your tools, and runs on infrastructure you own.
Not a chatbot in a browser tab. A co-worker. All open source. All user-owned. No vendor lock-in.
