FACEIT Light Client

A lightweight Windows client for FACEIT written in Rust.

Note

The official FACEIT client uses a lot of background resources just to display a website.
This project takes a different approach by wrapping wry and tao around the native Windows WebView2 engine.
The result is a client that uses the absolute minimum amount of RAM and CPU possible.

So, what's special?

• WebView2: No bundled Chromium or heavy frameworks. It just uses the engine already built into Windows.
• Lowest Priority: As soon as the app starts, it forces its own Windows process priority to IDLE_PRIORITY_CLASS.
• Built-in Tracker Blocker: Injects a strict Content Security Policy (CSP) and JavaScript hooks to kill background requests to trackers.
  • Blocks Sentry, Mixpanel, Google Analytics, DoubleClick, Usercentrics, etc.
  • Interceps fetch, XMLHttpRequest, WebSockets, and sendBeacon to stop Telemetry and Analytics.
• Saves Login State: Your session is saved in the Windows AppData folder, so you don't have to log in every time.
