Millennium is an open-source modding framework for the desktop Steam Client that lets users create, manage, and install custom CSS themes and JavaScript plugins. It patches the Steam client at runtime, ships a plugin loader and developer API, and blocks Steam analytics and crash reporting by default.
Use cases
- customize the Steam client with custom CSS themes
- install community plugins to extend Steam functionality
- develop my own Steam client plugin with JavaScript
- block Steam analytics and crash reporting
- make Steam look like a different app or wallpaper
- live-edit Steam client CSS with an inbuilt editor
When to choose
- you want to theme or extend the desktop Steam Client on Windows or Linux
- you want a plugin API and theme manager maintained actively by a community
- you want a privacy-friendly Steam client without telemetry
When to avoid
- you use Steam installed via Flatpak or Snap, or on ARM-based Linux distributions
- you only play games and never want to modify the Steam client
- you need console (Steam Deck handheld UI) or mobile Steam customization
