Open Source Git Tools
Git is a distributed version control system that records changes to files, especially source code, so people can review work, restore earlier versions, and collaborate without overwriting one another. Its branches let developers work on features or fixes in parallel, while commits and merges help track how changes fit together. Git also supports workflows ranging from individual projects to large teams coordinating contributions across different locations.
Open source tools in this area include graphical and terminal clients, hook managers, diff utilities, worktree helpers, code hosting platforms, and workflow automation. When choosing one, consider its license, maturity, maintenance activity, platform and Git version requirements, and compatibility with your existing tools and practices. These tools can help individual developers, project maintainers, and teams improve code review, manage parallel work, and automate routine tasks.
