Lightweight and memory-efficient, Muxy is a terminal emulator for macOS built with SwiftUI and libghostty. It targets developers and power users seeking enhanced organization and productivity through features like project-based workspaces, vertical tabs, and split panes, offering a native macOS experience with extensive customization.

How It Works

Muxy leverages SwiftUI for a modern, native macOS user interface and integrates libghostty for its terminal rendering engine, aiming for memory efficiency and performance. Key architectural choices include organizing terminals by project with persistent workspace states, a sidebar for vertical tabs with drag-and-drop, and support for horizontal/vertical split panes, enabling a highly organized and customizable terminal environment.
