OpenBin — free, open-source AI reverse engineering & decompilation
OpenBin.ai (officially The Open Binary Project)
is a free, open-source, collaborative platform for AI-assisted reverse
engineering, decompilation, and malware analysis. Drop in a sample, plug in
your own LLM key, and let intelligent agents help you decompile, understand,
and debug unfamiliar code — then publish your findings and build on the work
of other researchers. It runs in your browser; your projects live in the
cloud, so your work is accessible anywhere and shareable with your team.
What you can analyze
- Native binaries — ELF, PE, and Mach-O executables, decompiled to pseudo-C with Ghidra and shown side-by-side with disassembly.
- Android APKs — JADX decompilation with IDE-style navigation (via OpenAPK.ai).
- npm packages — and loose JavaScript / TypeScript, for supply-chain malware review.
- PyPI packages — and loose Python scripts.
- PowerShell — .ps1 / .psm1 scripts.
- Shell scripts — bash, sh, and zsh.
What it does
- AI decompilation and reverse engineering with file:line citations on every answer.
- Side-by-side decompiled code and disassembly with Ghidra-style cross-highlighting.
- Call-chain tracing, crypto/obfuscation detection, and string & import analysis.
- A collaborative community feed: publish reports, cite findings, credit researchers.
- Bring your own LLM key (Anthropic, OpenAI, AWS Bedrock) — you pay $0 for inference.
