Ghost OS

Ghost OS

1,200+ stars

Full 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.

Terminal
$brew install ghostwright/ghost-os/ghost-os && ghost setup

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.

Specter

v0.1.0

Deploy AI agents to dedicated VMs in 90 seconds. Interactive TUI. Automatic DNS and TLS. You own the infrastructure.

Terminal
$brew install ghostwright/specter/specter
$specter init
$specter# launch the interactive TUI

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.

Infrastructure

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.
