OpenOSRS is a fully open-source client with no restrictions. We are not affiliated with Jagex or RuneLite.

This is a special branch that uses the upstream client (RuneLite) with the OpenOSRS injector. (bundled)

From the root module, run the following gradle tasks:
clean build run

This branch is still in bringup but most functionality works as intended.
This branch uses upstreams PlayerManager/OverlayManager etc so keep that in mind if porting a plugin.

Contributions are welcome, but there should be no changes made to runelite-client unless necessary/minor. Mould the api around the client.

• cache - Libraries used for reading/writing cache files, as well as the data in it
• deobfuscator - Can decompile and cleanup gamepacks as well as map updates to newer revs
• http-api - API for runelite and OpenOSRS
• injector - Bytecode weaver that allows us to add code to the obfuscated gamepack
• runelite-api - RuneLite API, interfaces for accessing the client
• runelite-mixins - Classes containing the Objects to be injected using the injector-plugin
• runescape-api - Mappings correspond to these interfaces, runelite-api is a subset of this
• runelite-client - Game client with plugins
• wiki-scraper - Scrapes the runescape wiki https://oldschool.runescape.wiki for the latest npc data

We have migrated the project to Gradle. Information on how to setup and build the project can be found at https://github.com/open-osrs/runelite/wiki/Building-with-IntelliJ-IDEA

Installers for Windows, Mac and Linux can be found at https://github.com/open-osrs/launcher/releases
