Ghostty vs Alacritty

Ghostty is designed to feel like a first-party Apple app. It uses native macOS window decorations, supports native tabs (which can be dragged and merged), and integrates smoothly with macOS window management. It respects system themes automatically and offers a polished 'out of the box' experience that requires zero configuration to look good.

Alacritty uses a custom rendering window that, while functional, often looks distinct from native macOS apps. It lacks native tabs entirely, forcing users to rely on tmux or window managers for multi-shell workflows. While you can customize the window decorations to some extent, it never quite achieves the 'native' Mac aesthetic.

Ghostty supports font ligatures (e.g., combining '=>' into a single arrow glyph) by default, a must-have for many modern developers. Its font rendering engine is sharp, handling high-DPI (Retina) displays effortlessly via Metal, and supports advanced font features like stylistic sets.

Alacritty explicitly rejects ligature support, citing performance and complexity concerns. While its text rendering is crisp and accurate, the lack of ligatures is a dealbreaker for users accustomed to modern coding fonts like Fira Code or JetBrains Mono.

Ghostty includes built-in support for splits and tabs. You can split panes horizontally or vertically using simple shortcuts, similar to iTerm2. While not as scriptable as tmux, it covers the needs of 90% of users who just need to view two logs side-by-side.

Alacritty has zero built-in multiplexing. It relies entirely on external tools like tmux or Zellij. If you don't know how to use a multiplexer, Alacritty is effectively a single-window terminal. However, for tmux power users, this 'stay out of the way' approach is a feature, not a bug.

Ghostty implements the Kitty graphics protocol, allowing CLI tools to render high-resolution images, plots, and even videos directly in the terminal. This makes it incredibly strong for data science workflows or modern TUI file managers like Yazi.

Alacritty does not support image protocols like Sixel or Kitty graphics. It is strictly for text. Users needing to preview images must rely on external window hacks or switch terminals, limiting its utility for modern, media-rich CLI workflows.

Ghostty uses a simple, straightforward configuration file. Uniquely, it offers a built-in command ghostty +show-config to view defaults and current settings. Its defaults are sensible enough that many users never touch the config file.

Alacritty uses TOML (formerly YAML) for configuration. It is strong and allows for hot-reloading (changes apply instantly). However, you must configure it to get basic functionality (like keybindings for specific workflows) working, as the defaults are very barebones.

Ghostty's architecture allows it to process input and render frames virtually as fast as Alacritty. In 2026 benchmarks, the input latency difference is negligible (often <2ms difference). It handles massive log outputs without freezing, using the GPU effectively.

Alacritty remains the gold standard for raw throughput and input latency. It is technically faster in synthetic benchmarks and has a slightly lower overhead. For users on older hardware, Alacritty feels snappier, but on Apple Silicon, the difference is imperceptible.

Ghostty is efficient but heavier than Alacritty due to its richer feature set and native UI integration. Expect it to use 50-100MB more RAM per instance compared to Alacritty, which is a worthy trade-off for the features provided.

Alacritty is incredibly lightweight. It starts up instantly and consumes minimal RAM, making it the perfect candidate for keeping dozens of instances open or running on constrained hardware.

Ghostty ships polished macOS and Linux (GTK) apps. Official 1.3 roadmap text still treats a full Windows desktop app as not planned for the near term, with libghostty as the longer path. Do not pick Ghostty if your fleet must share one native terminal binary on Windows laptops.

Alacritty is a first-class Windows citizen with the same TOML-centred workflow as macOS and Linux. Teams that keep one alacritty.toml across three OSes keep Alacritty for that reason alone.

Ghostty 1.3 added the basics many users refused to live without: scrollback search with standard macOS Find shortcuts, native overlay scrollbars, and command-finished notifications after long builds. That closed the gap that once pushed people toward iTerm2 or Kitty even when they liked Ghostty speed.

Alacritty has vi-mode navigation and scrollback search in its own model, but it still refuses to grow a full native tab UI. Search and navigation exist; window management does not become a product surface.
