About:
Luyten is a standalone graphical decompiler for Java bytecode, built on the Procyon decompiler engine. It provides a user-friendly interface for reverse engineering compiled Java applications, allowing developers to inspect .jar, .class, and other Java archive files without needing command-line tools.
Key Features:
  • Graphical user interface for Java decompilation
  • Built on the Procyon decompiler engine
  • Supports .jar, .class, .war, and .zip files
  • Syntax highlighting and clickable navigation
  • Standalone application requiring no installation
Use Cases:
  • Reverse engineering and analyzing compiled Java applications
  • Recovering lost source code from Java bytecode
  • Educational purposes for understanding Java compilation and bytecode
Alternatives:
  • JD-GUI – Another popular GUI Java decompiler, but Luyten is often favored for its active development and Procyon backend.
  • Bytecode Viewer – A more feature-rich tool that includes multiple decompilers and bytecode analysis, whereas Luyten is focused on a clean Procyon GUI.
