The terminal emulator landscape is evolving rapidly, with developers leveraging modern hardware, GPU acceleration, containerization, and even AI/LLMs to enhance console experiences. Enter Ghostty, a new open-source, cross-platform terminal emulator from HashiCorp co-founder Mitchell Hashimoto.

Hashimoto's vision for Ghostty is simple: a fast, feature-rich terminal with a platform-native GUI, all while maintaining cross-platform compatibility. The initial release, around Christmas, showcased a promising tool hinting at the future of terminal emulation.

Platform-Native GUI: A Defining Feature

Unlike cross-platform alternatives like Warp, Ghostty prioritizes a native GUI. Many terminals use custom or web-based UIs for convenience or cross-platform consistency. Ghostty's approach differs. It utilizes Zig and GTK4/libadwaita on Linux, and Swift, AppKit, and SwiftUI on macOS, resulting in a visually integrated and system-aware interface. Native windows, menus, and fonts ensure a seamless user experience, unlike some terminals that feel detached from the underlying OS.

Ghostty's Features: Speed and Functionality

Ghostty 1.0, the first stable release (following a beta period with exclusive YouTube access), has already generated significant excitement due to its speed and feature set. While many crucial terminal aspects—shell integration and process management—are often invisible, they are fundamental to a powerful emulator. Ghostty excels in these areas while maintaining a clean user interface.

Key Features of Ghostty 1.0:

• Rapid startup and launch times.
• Multiple windows, tabs, and split panes.
• macOS integration with Quicklook and secure input API.
• Linux support for GTK single app process, primary clipboard, and IME input.
• GPU-accelerated rendering (OpenGL on Linux, Metal on macOS) for smooth performance.
• Extensive theming options (100 built-in themes and custom support).
• Full system keyboard shortcut support.
• Automatic shell integration (bash, zsh, fish, elvish).
• Dynamic prompt redrawing on window resize.
• Ligature and variable font support for improved text rendering.
• Xterm compatibility and Kitty graphics protocol support.

Ghostty's GPU-accelerated rendering and custom shader support, combined with grapheme clustering, provide superior font and text handling, creating a polished, modern experience.

Installing Ghostty on Ubuntu

While macOS installation is straightforward (download the binary), Ubuntu users must compile from source. Official packages exist for Arch Linux and a Nix flake for containerized environments.

Download the latest release from the Ghostty GitHub page, extract the archive, navigate to the directory in your terminal, and install using these commands:

sudo apt install libgtk-4-dev libadwaita-1-dev
sudo snap install --beta zig --classic
zig build -p $HOME/.local -Doptimize=ReleaseFast
sudo zig build -p /usr -Doptimize=ReleaseFast

After compilation, launch Ghostty from your application launcher.

Conclusion

Ghostty shows promise as a leading terminal emulator, particularly for developers who prioritize performance, native integration, and a modern interface. Its GPU acceleration, cross-platform compatibility, and user-friendliness make it a strong contender. While Ubuntu installation currently requires compilation, future distribution packages may simplify this process. Give Ghostty a try and share your feedback!
