libgit2 is a portable, pure C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Language bindings like Rugged (Ruby), LibGit2Sharp (.NET), pygit2 (Python) and NodeGit (Node) allow you to build Git tooling in your favorite language.

libgit2 is used to power Git GUI clients like GitKraken and gmaster and on Git hosting providers like GitHub, GitLab and Azure DevOps. We perform the merge every time you click "merge pull request".

libgit2 is licensed under a very permissive license (GPLv2 with a special Linking Exception). This basically means that you can link it (unmodified) with any kind of software without having to release its source code. Additionally, the example code has been released to the public domain (see the separate license for more information).
