What it is

Jagex Launcher is a free desktop application for discovering, installing, and playing games from the RuneScape universe. Its library links to RuneScape, Old School RuneScape, and RuneScape: Dragonwilds, with access through one Jagex Account login. It runs on Windows and macOS and can find existing RuneScape or Old School installations or install them. For Old School, users can switch between RuneLite and the official client; RuneLite can be downloaded when needed. The Launcher can run RuneScape and Old School simultaneously, including multiple instances of one game, but one character cannot be logged into both at once. A Jagex Account is required. Jagex Accounts require two-factor authentication by default, using email or an authenticator app, with 10 one-time backup codes. The Launcher itself does not require administrator access to install, although installing the official Old School client does. There is no built-in Quick Launch option; a Windows-only shortcut workaround is described. Jagex is based in Cambridge, United Kingdom.
