Ghostty — Fast Feature-Rich Cross-Platform Terminal Emulator

What it is

Ghostty is a cross-platform terminal emulator written in Zig by Mitchell Hashimoto, co-founder of HashiCorp. It uses platform-native UI elements (AppKit on macOS, GTK on Linux) combined with GPU-accelerated text rendering. Unlike Alacritty which strips features for speed, Ghostty aims to be both fast and feature-rich, with native tabs, splits, and OS integration.

Ghostty targets developers who want terminal rendering speed comparable to Alacritty but with built-in window management features and native OS integration.

How it saves time or tokens

Ghostty eliminates the need for tmux or a tiling window manager for basic multi-pane workflows. Native tabs and splits work with OS keyboard shortcuts. GPU rendering keeps output smooth during heavy builds or log tailing. The native UI means system features like notifications, clipboard, and font rendering work correctly without configuration.

How to use

1. Install Ghostty:

brew install --cask ghostty    # macOS

1. Configure via the config file:

# ~/.config/ghostty/config
font-family = JetBrains Mono
font-size = 14
theme = catppuccin-mocha
window-padding-x = 8
window-padding-y = 8
cursor-style = bar

1. Use built-in splits and tabs:

Cmd+D          # Split right
Cmd+Shift+D    # Split down
Cmd+T          # New tab
Cmd+W          # Close pane

Example

A complete Ghostty configuration:

# ~/.config/ghostty/config
font-family = Fira Code
font-size = 13
font-feature = calt
font-feature = liga

theme = tokyo-night
background-opacity = 0.95

window-padding-x = 10
window-padding-y = 10
window-decoration = true

cursor-style = bar
cursor-style-blink = true

shell-integration = zsh
confirm-close-surface = false

Common pitfalls

• Ghostty is relatively new and may have fewer themes and plugins than established terminals like iTerm2 or Kitty. Check the theme gallery before switching.
• Linux support requires GTK4 and specific graphics drivers. Some distributions may need manual dependency installation.
• Font ligature support exists but requires explicit font-feature configuration in the config file.
