GitWarren

Code review for your own git repositories, on your own machines. Your machines, your agents, no one else's server — and no account.

Built for the moment a coding agent — Claude Code, Codex, or anything else that edits files on your disk — has just finished, and its work is sitting in your worktree uncommitted. Read that diff here, on your own machine, before it becomes a commit.

gitwarren.com has downloads for macOS, Windows and Linux.

What it does

Tell GitWarren which local git repositories you care about, then open reviews against them — a review is a comparison of two refs, presented the way a pull request is, with conversation, commits and files changed tabs, and a browse files tab for the code the change did not touch.

• Review work before it is a commit. If the branch you are reviewing is checked out in a worktree, GitWarren finds that worktree — wherever it is — and folds its staged, unstaged and untracked changes into the diff. That is exactly when review is most useful, and it is the part that makes this worth having.
• Prose as well as code. Diffs read unified or side by side, with the changed words picked out of a changed line. A Markdown file can be read rendered, with its edits marked like tracked changes, and commented on paragraph by paragraph.
• Nothing is cached. Every branch name, commit and diff on screen is read from git at the moment it is shown.
• Nothing leaves your machine. Reviews live in one SQLite file in your application-data directory. No account, no telemetry; the desktop app's one outbound request is the update check.
• Agents are first-class. Local AI agents get the same capabilities through an MCP server over stdio — they open reviews, read your comments, reply in a thread and resolve what they fixed.
• Desktop app or browser. It runs as an Electron app on macOS, Windows and Linux, or as a command that serves the same review UI into a browser tab. Same renderer either way; the shell is the only thing that differs.
• Your other machines too. A machine with no screen at all — a VPS, a WSL distro, a box an agent works on — runs the headless half and is reviewed from somewhere else, over SSH, over wsl.exe, or over your own tailnet, and its repositories are listed on the same home screen as this machine's. Reviews live on the machine the code is on and stay there; nothing is replicated or relayed anywhere but the computers you already own.

Comments go on the line, the way a pull request does them. The agent that wrote the code answers in the same thread, while you are still reading the diff:
