The Jagex launcher and Jagex Accounts are now supported on Linux through our Linux Launcher beta! To download this, please click the button below.
This will look different to the Jagex Launcher that is on Windows and Mac, however once you've installed it and logged into your Jagex Account, you'll see a drop down to select your character.
The only supported client at this stage of the beta is OSRS via RuneLite, however we're looking to support RuneScape for Linux users before the end of the year.
