LiteLoader Logo

LiteLoader is a lightweight mod framework designed primarily for client-side mods. It aims to provide a wide array of features as possible whilst having minimal footprint and very low impact game performance when features are not in use.


  • Simple callback system based on interfaces. Simply implement the interfaces your mod needs
  • Powerful class transformers. If LiteLoader can't meet your needs "out of the box", you have a wide selection of powerful class transformers at your fingertips. It provides access to cutting edge transformers developed for LiteLoader but also used by the wider modding community. This guarantees that LiteLoader's transformers are the most stable and powerful libraries available
  • Tiny footprint. Liteloader injects minimal code into the game, and uses native bytecode injection for maximum performance. LiteLoader makes use of Java libraries shipped with the base game such as Gson rather than bundling a slew of optional libraries
  • Native bytecode event handlers. Liteloader generates raw java bytecode for event callbacks, this makes its event handlers blazing fast
