Bytecode Viewer

Konloch

💡 Choose it when you need several Java decompilers and quick class-file analysis in one desktop tool.

Bytecode Viewer is a free Java bytecode inspection and decompilation tool for developers, security researchers, and reverse engineers. It combines multiple decompilers,...

Pros

Bundles several Java decompilers and disassemblers in one interface
Supports browsing archives and inspecting classes without a build environment
Includes bytecode editing and analysis features beyond basic decompilation

Cons

Interface is less polished than dedicated tools such as Recaf or JD-GUI
Results depend on bundled decompiler versions and can vary between engines
Uses more memory than lightweight command-line decompilers

Krakatau

Storyyeller

💡 Choose it when precise, scriptable control of JVM instructions matters more than a graphical interface.

Krakatau is an open-source Java class-file assembler, disassembler, and decompiler for developers and reverse engineers. Its text-based workflow gives precise control over...

Pros

Offers finer low-level control than JBED
Useful for reproducible, scriptable bytecode changes
Text assembly makes changes easy to review and version

Cons

Much steeper learning curve than JBED
Lacks a conventional graphical editor
Requires familiarity with JVM bytecode syntax

Javassist

Shigeru Chiba

💡 Pick it when bytecode changes should be automated inside a Java application or build pipeline.

Javassist is a Java library for inspecting and modifying bytecode at runtime or during build processes. It is intended for developers embedding...

Pros

Simpler Java API than manipulating raw class-file structures
Well suited to automated build and runtime transformations
Can modify classes programmatically without a separate editor

Cons

Not a standalone visual editor like JBED
Less precise than ASM for advanced bytecode work
Requires writing and maintaining Java transformation code
