JD-GUI

JD-GUI is a standalone graphical Java decompiler that allows users to reconstruct and explore source code from compiled .class files. It provides an intuitive interface for browsing decompiled code, making it easier to inspect methods, fields, and class structures without access to original source files. The tool is widely used for reverse engineering, debugging, and understanding third-party libraries. It supports opening individual files as well as entire archives such as JARs, enabling efficient navigation across large codebases. JD-GUI emphasizes simplicity and accessibility, allowing developers to quickly analyze compiled Java applications. It integrates with standard Java tooling and can be extended with additional modules. Overall, it is a practical utility for developers working with bytecode-level artifacts.
