Introduction

Git Extensions is a free, open-source standalone Git GUI and Visual Studio extension. It provides a comprehensive graphical interface for virtually every Git operation, from basic commits to advanced rebasing, submodule management, and bisect workflows.

What Git Extensions Does

• Displays a full commit graph with branch labels, tags, and merge visualization
• Provides interactive staging with line-by-line and hunk-by-hunk selection
• Supports interactive rebase with drag-and-drop commit reordering
• Manages submodules, stashes, and worktrees through dedicated panels
• Integrates as a Windows shell extension and Visual Studio 2019/2022 plugin

Architecture Overview

Git Extensions is written in C# targeting .NET and uses Windows Forms for the UI. It shells out to a standard Git installation for all operations, parsing the output for display. The architecture supports plugins for custom commands, hosting providers, and merge tools.
