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
