Ghostty terminal theme browser with live preview TUI. Browse, filter, and apply themes with real-time palette display.

Installation • Usage • Theme Discovery

• Live preview — applies themes in real-time, signals running Ghostty to reload via SIGUSR2
• TUI interface — ratatui-based terminal UI with syntax-highlighted Rust code preview
• Dark/light filtering — toggle between all, dark, and light themes
• Name search — filter themes by name with / search mode
• Palette display — 16-color palette grid with background, foreground, and sample code rendering
• Plain text listing — --list flag for non-TTY environments and scripting
• Undo on cancel — restores the previous theme if you cancel without confirming

gsty searches these paths for Ghostty theme files:

/Applications/Ghostty.app/Contents/Resources/ghostty/themes
/opt/homebrew/share/ghostty/themes
/usr/share/ghostty/themes
~/.config/ghostty/themes

Selected themes are applied to ~/.config/ghostty/auto/theme.ghostty. Ghostty reloads its theme automatically via the SIGUSR2 signal.
