About libgit2/libgit2
libgit2 is a portable, pure C implementation of the Git core methods, provided as a linkable library with a solid API. It allows developers to build Git functionality directly into their applications. Written in C, it can be used from many programming languages through bindings (e.g., Ruby, .NET, Python, Node.js, Rust). The library is used in a variety of places, from GUI clients to hosting providers and countless utilities. It is licensed under GPLv2 with a special Linking Exception, making it permissive for linking with any software. The project is actively maintained with over 10,000 stars and supports cross-platform builds via CMake.
