Jagex Launcher

Contains notes for native Linux RuneLite and RS3 NXT clients to run through wine-handled Jagex Launcher via symlinks

New C++ Client

Runs Jagex Launcher and the new C++ client through Wine, surprisingly well!

Uses traditional RuneScape-specific username/email/password account log-in

Does not support Jagex Accounts and may be deprecated in the future

RuneLite

Java

Java (legacy)

New Official Client & Next Steps - OSRS News

The Java client isn't offered as an option from the Jagex Launcher unless you had a previous install of it prior to the new C++ client option

The notes should work and Jagex claims to continue supporting the Java client, but you have to supply your own Jagex Launcher back-up for this configuration and I have no way of testing this as of 2023/07/23

Allows sign-in with Google, Facebook, and Apple, but these log-ins are untested

Allows traditional RuneScape-specific username/email/password account log-in
