Jagex Launcher

What Jagex Launcher is

Jagex Launcher is a free desktop app for discovering, installing, and playing games from the RuneScape universe. Its library links to RuneScape, Old School RuneScape, and RuneScape: Dragonwilds, and a single Jagex Account login provides access to Jagex games. It runs on Windows and macOS. The Launcher can find existing RuneScape or Old School installations, or install them itself. For Old School, users can switch between RuneLite and the official client; the Launcher can download RuneLite when needed.

It can run RuneScape and Old School at the same time, including multiple instances of one game, but the same character cannot be logged into both games simultaneously. A Jagex Account is required. Jagex says its accounts require two-factor authentication by default, with login codes available by email or authenticator app and 10 one-time backup codes for recovery. The Launcher itself does not require administrator access to install, but installing the official Old School client through it does. A built-in Quick Launch option is unavailable; the FAQ describes a Windows-only shortcut workaround. Jagex is based in Cambridge, United Kingdom.
