Minimal macOS terminal built with Swift and libghostty
Justty is a minimal native macOS terminal built with SwiftUI and libghostty. It focuses on quick command-line use rather than trying to match every Ghostty feature, which makes the app a lighter-weight terminal option for everyday shell work.
The project ships with documented install paths through a Homebrew tap and release downloads, plus setup notes for self-signed builds, quarantine handling, and source builds. It requires macOS 15.6+ and can be built from source with Xcode 16+ and the macOS SDK.
Core features
Real shell sessions
Terminal sessions use a real PTY through Ghostty’s .exec mode, with the shell launched from the user account and app sandboxing left off so shells can spawn normally.
Context-aware tabs
Tab titles follow the running shell or program, and new tabs open in the active tab’s working directory when available.
Built-in find
Search within terminal output with Cmd+F, highlight matches in scrollback, and move through results from the find bar.
Configurable appearance and layout
Adjust font family, size, weight, line height, padding, window position, and grid dimensions from Settings, with preferences saved to config.yml.
Theme support
Choose light and dark themes from the GhosttyTheme catalog, with app chrome and window styling matched to the selected theme.
Where Justty fits
Everyday terminal work
Use Justty when you want a native terminal for running shell commands, checking logs, or doing quick command-line tasks without a more complex terminal workflow.
Managing multiple sessions
Use the tab and window controls to keep several shell sessions open at once while switching between commands, directories, or processes.
Customizing the terminal UI
Adjust font, spacing, size, and theme settings when you need the terminal to match your display preferences or window layout.
Homebrew-based installation
Use the Homebrew tap when you want an install flow that is documented and includes a cask that clears quarantine on install.
Source-based development
Build from source if you need to inspect or modify the app, using the documented Xcode and submodule setup steps.
Pros and Cons
Pros
- Uses a real PTY shell session via Ghostty .exec.
- Supports multiple windows and tabs with standard macOS shortcuts.
- Includes theme, font, padding, and layout controls in Settings.
- Offers Homebrew installation with quarantine removal handled for users.
Cons
- Notary signing is not used, so Gatekeeper prompts are expected on manual installs.
- The app intentionally does not cover several Ghostty features, including splits, panes, inspector support, and custom profiles.
- Building from source requires Xcode 16+ and the Git submodules to be present.
FAQ
What is Justty?
Justty is a native macOS terminal app built with Swift and libghostty. The source describes it as a minimal terminal suited to quick commands rather than full Ghostty parity.
How do I install it?
The documented installation path is Homebrew: trust the tap, tap 0x96f/justty, and install the justty cask. The README also describes a manual install from the latest release zip.
What platform does it support?
The project states macOS 15.6+ is required. It also needs Xcode 16+ with Swift 5 and the macOS SDK only if you want to build from source.
Does it need special handling on first launch?
No. The notes say Justty is self-signed and not notarized, so macOS may show Gatekeeper warnings on first launch. Homebrew installs clear quarantine automatically, while manual installs may need the Open workflow or a quarantine removal step.
What features does it not include?
The docs say Justty is not meant to expose full Ghostty capability. Features such as splits, panes, inspector support, custom ghostty.conf profiles, and remappable shortcuts in the UI are listed as out of scope.
