About rdbo/libmem

Libmem is an advanced, cross-platform game hacking library written in C, with bindings for modern C++, Rust, and Python. It provides a comprehensive suite of features for process and memory manipulation, including reading/writing memory, allocating and protecting memory regions, scanning memory for patterns/signatures, resolving pointer maps, hooking and detouring functions, assembling and disassembling code (JIT), VMT hooking, and loading/unloading modules. The library supports internal (in-process) and external (out-of-process) techniques across Windows, Linux, and FreeBSD (x86/x64), with untested support for ARM and AArch64. Its open-source nature (GNU AGPLv3) and active community (via Discord) make it a powerful tool for game hacking, modding, reverse engineering, and educational purposes.

Enumerate process threads

Pros & Cons

Pros
  • Cross-platform: Windows, Linux, FreeBSD with x86/x64 support
  • Multiple language bindings: C, C++, Rust, Python
  • Comprehensive feature set covering memory, hooking, disassembly, and module injection
  • Open source (GNU AGPLv3) with an active community (Discord)
  • Well-documented with code examples in multiple languages
Cons
  • AGPLv3 license may be restrictive for proprietary commercial projects
  • ARM/AArch64 support is untested and may be unstable
  • Focus on game hacking may limit applicability in other domains
