arRPC Browser by Fless

arRPC Browser connects Discord Rich Presence to supported desktop games through a lightweight browser extension and a local Node.js helper. It works with Firefox and Discord Web, allowing your game activity to appear on your Discord profile without requiring the Discord desktop application.

The extension communicates with a local helper running on your computer, which detects supported running games and relays activity information to Discord Web. The extension is lightweight and does not bundle a separate browser runtime.

Requirements: Desktop Firefox, a signed-in Discord Web session, Node.js, and the arRPC helper running locally.

This add-on is intended for desktop Firefox. Firefox for Android is not supported.
