Why Kurotty

A terminal that feels built for the machine it runs on.

Tabs, splits, menus, clipboard, notifications, and IME stay in the macOS layer. Parser, grid, scrollback, and rendering contracts move toward a tighter Zig and Metal core.

Native surface

macOS windows, tabs, splits, menus, pasteboard, and input live where they belong.

Sharp renderer

Metal draws glyphs, backgrounds, cursor, underline, and strikethrough with direct control.

Terminal detail

16-color, 256-color, truecolor, OSC title, working directory, and notification paths are already in motion.

Open source

Built in public, tuned for terminal people.
