Montty

A macOS terminal app built on GhosttyKit (MIT licensed) with vertical tabs, splits, and session persistence.

Features

• Vertical tab sidebar with large, scannable names, and a minimap of terminal surfaces across tabs
• Per-tab color coding (user-assignable or auto from directory)
• Horizontal and vertical splits within tabs
• Session restore (tabs, splits, names, colors, focus state survive restart)
• Click any minimap pane to jump directly to that surface
• Git branch and directory info in tab sidebar
• Claude Code status indicators (working, waiting, idle) on minimap panes
• Standard Ghostty theming from ~/.config/ghostty/config
• Surface jump (Cmd+;) for ace-jump/easy-motion style navigation across all panes

Easy Motion allows movement directly to any terminal surface across tabs:

Build from source

Requires macOS 14+, Xcode, zig 0.15.2, and just.

just setup      # init submodules, build GhosttyKit
just build      # compile the app
just run        # build and launch
just test       # run unit tests
just lint        # run SwiftLint

Configuration

Terminal theming is configured through Ghostty's config file at ~/.config/ghostty/config. Tab state (names, colors, positions, splits) is persisted automatically in a session file. No separate montty config file is needed.

The surface jump shortcut (default Cmd+;) can be changed through macOS System Settings under Keyboard, Keyboard Shortcuts, App Shortcuts. Add an entry for Montty with the menu title "Jump to Surface".

Architecture

• Sources/Ghostty/ contains MIT-licensed Swift bindings copied from Ghostty. Modifications are marked with // MONTTY: comments.
• Sources/Model/ contains the data model (tabs, splits, session snapshots, jump labels). This is where most testable logic lives.
• Sources/View/ contains SwiftUI views.
• Sources/App/ contains the app entry point, AppDelegate, and servers (debug HTTP, hook socket).
