About

arRPC is an open source implementation of Discord's local RPC servers. It allows applications with Discord Rich Presence support to display their status on Discord Web, custom clients, and other platforms that don't natively support RPC.

TypeScript + Bun port of the original arRPC by OpenAsar, featuring full type safety, Bun native APIs, and improved performance.
