Advertiser disclosure: iTechGuides is reader-supported. Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Free open-source framework for native-code disassembly and decompilation
  • Supports Java and DEX bytecode analysis alongside native architectures
  • Includes debugging, scripting, headless analysis, and plugin support
  • Analyzes ELF, PE, Mach-O, COFF, archives, Intel HEX, and raw machine code
  • Reconstructs C++ classes, symbols, types, functions, and higher-level constructs
  • Generates C or Python-like output, disassembly, call graphs, and control-flow graphs
Cons
  • Its broad feature set may require a technical reverse-engineering workflow
  • Plugin and scripting extensions add configuration choices to the environment
  • Focused on compiled-program analysis rather than general software development
  • The official repository describes the project as being in limited maintenance mode
  • Locally installed workflows may require more technical setup than hosted tools
  • Its focus is executable analysis rather than an all-purpose reverse-engineering suite
