Tessellate
Tiled terminal manager for macOS. See all your terminal sessions at a glance in side-by-side panes — built for developers running multiple AI coding agents in parallel.
Features
Tiled Terminal Panes
See all your terminal sessions at a glance in an auto-arranging grid — up to 10 panes visible simultaneously. No tabs to switch between, everything is right in front of you.
Colored Status Borders
Each pane shows a colored border indicating its state at a glance:
Gray
Idle — waiting for input
Blue
Working — producing output
Amber
Asking — needs attention
Green
Focused — currently selected
Resizable Splits
Drag dividers between panes to give more space where you need it. The layout adapts as you add or remove terminals.
Smart Pane Creation
Cmd+T opens a new terminal at the same directory as your current pane — jump right into context without navigating.
Full Keyboard Support
Every key works exactly as expected — ESC, Ctrl combinations, arrow keys, and function keys all pass through correctly.
Auto-Updates
Built-in Sparkle update system keeps you on the latest version automatically.
