Ghostty vs Alacritty

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.

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.

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.

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.

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.

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 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.
