GitWarren

GitWarren is a code review tool that reads local git worktrees directly before changes become commits.

GitWarren is a code review tool designed for developers working with local machines and coding agents. It reads worktrees directly—staged, unstaged, and untracked files—allowing users to review an agent's diff before a commit is ever made. It operates across laptops, VPS boxes, WSL distros, and Tailscale networks without sending code or data over the public internet. The platform includes an MCP server over stdio that allows agents like Claude Code, Codex, and Gemini CLI to participate directly in the review thread. The application runs as a native desktop app for macOS (Apple silicon and Intel), Windows, and Linux, or as a browser UI served via Node using npx gitwarren serve. It requires no account, stores reviews locally in a single SQLite file per machine, and is open source under GPL-3.0.
