RuneLite

RuneLite is a free, open‑source client for Old School RuneScape that runs on macOS, Windows and Linux. It replaces the default game client, offering a faster, more responsive experience while preserving full compatibility with the official game servers.

The client adds a range of optional overlays and tools, such as Discord Rich Presence integration, GPU‑accelerated rendering for higher frame rates and improved visual quality, a loot tracker that records monster drops and their market prices, and status widgets that display boost timers, enemy health and other in‑game information. These features are toggleable, allowing players to customize the interface to their preferences.

Developed and maintained by a community of contributors, RuneLite is released under a stable, mature version and is distributed for both Intel and Apple‑silicon macOS, as well as various Windows and Linux architectures.
