The Terminalizer

Randomize, preview, and hot-swap your Windows Terminal themes from a sleek web UI.

Features

• 515+ themes — browse and install from the iTerm2 Color Schemes collection
• Live preview — see how each theme looks before applying it
• Randomize — one click to switch to a random theme
• Auto-shuffle — cycle through themes on a timer (30s to 30m)
• Favorites — star the themes you love, shuffle from favorites only
• Font size control — adjust terminal font size from the UI
• Opacity slider — set window transparency with acrylic blur
• Search — filter through all installed and available themes

Install

npx the-terminalizer

Or install globally:

npm install -g the-terminalizer
the-terminalizer

Then open http://localhost:3456 in your browser.

Requirements

• Windows Terminal (installed from Microsoft Store)
• Node.js 14+
• Works on Windows and WSL

Configuration

By default, The Terminalizer auto-detects your Windows Terminal settings.json. If detection fails, set the path manually:

TERMINAL_SETTINGS_PATH="/path/to/settings.json" the-terminalizer

Change the port:

PORT=8080 the-terminalizer

How It Works

The Terminalizer reads and writes your Windows Terminal settings.json to swap color schemes in real time. Your favorites and theme cache are stored in ~/.terminalizer/.
