What is GitWarren?
GitWarren is a local desktop application for macOS, Windows, and Linux that lets developers review code written by AI coding agents before any changes are committed or pushed to a remote repository. Unlike traditional code review tools that operate on pull requests, GitWarren reads the dirty worktree directly, including staged, unstaged, and untracked files, so you can see exactly what an agent produced on your own machine first.
The tool includes an MCP server over stdio, allowing agents like Claude Code or Codex to participate in the review process. Agents can open reviews, read discussions, reply in threads, leave line comments, and resolve them, all attributed clearly as machine-written. Every review and comment is stored in a single local SQLite file, and nothing leaves your machine. No account, no sign-in, and no caching of git data ensures privacy and accuracy.
Key Features
- Reads staged, unstaged, and untracked files from the worktree for a complete diff
- MCP server over stdio for agent participation in reviews
- Machine-written comments are always attributed and distinguishable from human comments
- Multiple MCP sessions are tracked separately so two agents stay distinct
- Editable and deletable reviews and comments
- Local SQLite storage, no account, no sign-in, no cloud dependency
- No caching, every view reads directly from git at the moment it is shown
