Deprecation

The master branch is deprecated. All forward development should be based on the next branch.

To clone a fresh checkout with the next branch:

git clone -b next https://github.com/capstone-engine/capstone

To change to the next branch in an existing checkout:

git checkout next

We moved the original historical repo of Capstone from https://github.com/aquynh/capstone to an organization, where we can add more maintainers to the project, and push Capstone development forward.

Our new home is https://github.com/capstone-engine/capstone

Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community.

Created by Nguyen Anh Quynh, then developed and maintained by a small community, Capstone offers some unparalleled features:

  • Support multiple hardware architectures: ARM, ARM64 (ARMv8), Ethereum VM, M68K, Mips, MOS65XX, PPC, Sparc, SystemZ, TMS320C64X, M680X, XCore and X86 (including X86_64).

  • Having clean/simple/lightweight/intuitive architecture-neutral API.

  • Provide details on disassembled instruction (called “decomposer” by others).

  • Provide semantics of the disassembled instruction, such as list of implicit registers read & written.

  • Implemented in pure C language, with lightweight bindings for D, Clojure, F#, Common Lisp, Visual Basic, PHP, PowerShell, Emacs, Haskell, Perl, Python, Ruby, C#, NodeJS, Java, GO, C++, OCaml, Lua, Rust, Delphi, Free Pascal & Vala (ready either in main code, or provided externally by the community).

  • Native support for all popular platforms: Windows, macOS, iOS, Android, Linux, *BSD, Solaris, etc.

  • Thread-safe by design.

  • Special support for embedding into firmware or OS kernel.

  • High performance & suitable for malware analysis (capable of handling various X86 malware tricks).

  • Distributed under the open source BSD license.
