JAR-RE is a specialized tool designed to simplify the process of reverse engineering Java archives, with a particular focus on Old School RuneScape (OSRS) gamepack deobfuscation. While primarily built to enhance OSRS reverse engineering workflows, JAR-RE can be used to analyze and deobfuscate any JAR file.

- Java archive analysis and deobfuscation
- Tree view of classes within a JAR file
- Content panel for viewing and editing class code
- Structure panel for navigating methods and fields
- EventBus system for decoupled event handling
- Modern UI using FlatLaf for an enhanced user experience
JAR-RE is under active development. While it's already functional for basic JAR analysis, there are several planned enhancements to make it even more powerful and user-friendly.
- Enhance the IDE with features like line numbers
- Make the structure panel toggleable
- Implement scrolling to methods/fields when selected in the structure panel
- Add support for analyzing multiple JAR files simultaneously
- Develop a comprehensive refactoring tool
- Implement save functionality for modified classes
- Introduce custom theming options
- Create a custom script section for executing code on ClassNode, MethodNode, or FieldNodes
