Quick Start
git clone https://github.com/49Agents/49Agents.git
cd 49Agents
./49ctl setup # interactive setup (one time)
./49ctl start # start cloud server + agent
Open http://localhost:1071. No account, no login, no token.
We recommend self-hosting — it's free, your terminals and files never leave your
machine, and setup is two commands. If you just want to try it first, the
cloud-hosted version needs no install: 49agents.com
Desktop App (macOS)
Download the latest .dmg from GitHub Releases.
After downloading, macOS will block the app because it is not notarized. Run this once to allow it:
xattr -cr /Applications/49Agents.app
Then open 49Agents normally. It runs as a tray icon — look for it in your menu bar.
Updates are delivered in-app: click the tray icon and choose Check for Updates.
Features
Canvas and Workspace
- Infinite canvas — no tabs, no splits. Place panes anywhere on a zoomable surface
- Drag, resize, arrange — your workspace grows with your thinking, not your monitor
- Zoom levels — zoom out for the big picture, zoom in to focus
- Persistent layout — everything stays where you put it
Terminals
- Real tmux sessions via ttyd — full ANSI color, scrollback, your shell config
- Broadcast input — type once, send keystrokes to multiple terminals simultaneously
Multi-Machine
- Zero SSH — connect agents from any machine to one canvas
- HUD overlay — live CPU, RAM, and Claude API usage across all connected machines
Access
- Any device — laptop, tablet, phone. Same workspace, same layout
- Tailscale / LAN / hosted relay — works however you connect
- Fully self-hosted — the entire stack runs on your hardware
- No data stored server-side — terminal I/O is relayed, never persisted
Keyboard-First
- Tab chords for pane switching
- WASD move mode for spatial navigation
- Shortcut numbers (1–9) for instant pane focus
- Broadcast mode for multi-terminal input
