Ghostty vs Kitty: The Ultimate Showdown Between Two Modern Linux Terminal Powerhouses

In the ever-evolving landscape of Linux terminal emulators, two names have consistently risen to the top of the conversation among power users, developers, and system administrators: Ghostty and Kitty. Both applications represent the cutting edge of terminal technology, offering features that would have seemed impossible just a decade ago. But as with any competitive space, the question remains: which terminal emulator truly deserves a place in your workflow?

The Contenders: A Brief Introduction

Ghostty burst onto the scene in late 2024, developed by Mitchell Hashimoto, the creator of Terraform and a well-respected figure in the DevOps community. Built with performance as its North Star, Ghostty was designed from the ground up to be fast, modern, and visually stunning. Written in Zig with GPU acceleration, it promised to redefine what users could expect from a terminal emulator.

Kitty, on the other hand, has been a mainstay in the Linux community since its initial release in 2018. Created by Kovid Goyal, the developer behind the popular Calibre e-book management software, Kitty has steadily evolved into one of the most feature-rich terminal emulators available. It too leverages GPU acceleration and has built a loyal following among users who demand both performance and extensive functionality.

Performance: The Need for Speed

When it comes to raw performance, both terminals deliver exceptional results, but they take different approaches to achieve their goals.

Ghostty’s architecture is built around maximum efficiency. The developers made bold choices, including using the Zig programming language, which is known for its focus on performance and safety. Early benchmarks showed Ghostty rendering text at speeds that sometimes exceeded 10,000 frames per second on capable hardware—numbers that seemed almost absurd for a terminal emulator.

Kitty, while slightly older in its architecture, has been continuously optimized over the years. It uses OpenGL for rendering and has been fine-tuned to work exceptionally well even on lower-end hardware. In head-to-head tests, Kitty consistently delivers smooth performance even when handling large amounts of text output or complex terminal applications.

The real-world difference between the two is often negligible for most users. Both terminals handle multiple tabs, split panes, and heavy workloads without breaking a sweat. However, Ghostty’s newer architecture does give it a slight edge in extreme scenarios, such as rendering massive log files or running multiple resource-intensive terminal applications simultaneously.

Feature Set: The Battle of Capabilities

Here’s where things get interesting, as both terminals approach features from different philosophical standpoints.

Ghostty’s Strengths:

• Native macOS support with full integration
• Built-in window management that feels more like a modern application
• Excellent HiDPI support out of the box
• Advanced ligature support for programming fonts
• Native support for various image protocols
• A clean, minimalist interface that prioritizes content

Kitty’s Strengths:

• Extensive customization through a powerful configuration file
• Built-in support for images and kitten extensions
• Advanced Unicode support including emoji rendering
• Robust session management and restoration
• Highly configurable keyboard shortcuts
• Active development with frequent updates and new features

Kitty’s extension system, called “kittens,” allows users to add functionality without modifying the core application. These range from simple utilities like image viewers to complex tools for remote development. Ghostty, being newer, doesn’t yet have an extension ecosystem, though its plugin architecture is reportedly in development.

User Experience: The Daily Driver Test

Using both terminals daily reveals subtle but important differences in their design philosophies.

Ghostty feels more like a modern application. Its window management is intuitive, with smooth animations and a cohesive design language. The terminal integrates well with desktop environments, and its handling of multiple windows feels natural. The learning curve is relatively gentle, making it accessible to users transitioning from more traditional terminals.

Kitty, by contrast, feels more like a power tool. Its configuration file approach means that users can tailor nearly every aspect of the terminal to their liking, but this comes with a steeper learning curve. Once mastered, however, Kitty becomes an incredibly personalized tool that fits perfectly into established workflows.

The choice between them often comes down to user preference: do you want a terminal that works excellently out of the box with modern sensibilities (Ghostty), or do you prefer to build your perfect terminal through extensive customization (Kitty)?

Cross-Platform Support: Beyond Linux

This is an area where Ghostty has made significant strides. From its inception, Ghostty was designed to work seamlessly across Linux, macOS, and Windows. The Windows support, in particular, is noteworthy as it provides a genuinely native experience rather than relying on the Windows Subsystem for Linux (WSL) as a crutch.

Kitty has traditionally been Linux and macOS focused, though Windows support has improved over time. However, the Windows experience still feels somewhat secondary compared to the native Linux and macOS implementations.

Community and Development: The Long Game

Kitty benefits from a mature, established community. Its GitHub repository is active, with regular contributions from developers worldwide. The documentation is comprehensive, and solutions to common problems are readily available through community channels.

Ghostty, being newer, has a smaller but rapidly growing community. The development team is highly responsive, and the project has attracted attention from influential figures in the Linux and DevOps communities. However, users might find fewer third-party resources and community-developed solutions compared to Kitty.

The Verdict: Which Should You Choose?

After extensive testing and consideration, the answer isn’t as clear-cut as one might hope—and that’s actually a good thing for users.

Choose Ghostty if:

• You want cutting-edge performance with modern design
• You work across multiple operating systems and need consistent behavior
• You prefer a terminal that works excellently out of the box
• You value native application feel over extensive customization
• You’re excited about using newer technologies and languages like Zig

Choose Kitty if:

• You want maximum customization and control over every aspect
• You appreciate a mature, well-documented ecosystem
• You’re willing to invest time in configuration for a perfect setup
• You value an extensive extension system and community resources
• You prefer proven, stable technology over the latest innovations

The Future of Terminal Emulators

What’s particularly exciting is that both projects are pushing each other forward. Ghostty’s innovations in performance and modern design are forcing the entire terminal emulator ecosystem to raise its standards. Meanwhile, Kitty’s extensive feature set and customization options provide a blueprint for what power users truly need.

The competition between these two terminals represents something beautiful about open-source development: different approaches solving the same problems, with users ultimately benefiting from having genuine choices rather than settling for mediocrity.

As both projects continue to evolve, the gap between them may narrow, or they may continue to serve different niches within the power user community. Either way, the terminal emulator landscape is better for having both Ghostty and Kitty pushing the boundaries of what’s possible.
