Install

​
Prerequisites

Before installing Magnitude, make sure you have:
  • A modern terminal emulator, such as Ghostty or Kitty
  • Provider credentials or API keys

Note: The default macOS Terminal.app has limited color support and may look strange.

​
macOS / Linux

npm install -g @magnitudedev/cli

​
Windows

Magnitude requires WSL on Windows. We do not currently support native Windows environments.
To get started, run: 
wsl --install
Then restart your computer. After restarting, run wsl in your shell. Once you’re inside WSL, you can use the normal Linux install commands above to install and run Magnitude.

​
Configure

After installing, run: 
magnitude
When you first run magnitude, Magnitude walks you through a setup wizard that helps you:
  • Connect a provider
  • Choose recommended models
  • Set up the browser agent
If you already have one, we recommend using a ChatGPT subscription or GitHub Copilot subscription for the easiest setup. You can also configure providers and models anytime with /provider and /model. For the full list of supported providers and configuration options, see Providers and Models.
