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
