Common questions

Is GitWarren safe?

It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 28 days ago, and the latest version (1.0.1) reached the registry 28 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

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](https://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:

Install

The desktop app

Download it from [gitwarren.com](https://gitwarren.com), or on macOS:

brew install --cask klarluft/tap/gitwarren

The command line

Serves the same review UI in a browser instead of an Electron window — for a machine that will not have the app on it, or one with no screen at all:

brew install klarluft/tap/gitwarren-cli               # macOS and Linux, brings its own Node

curl -fsSL https://gitwarren.com/install.sh | sh # macOS and Linux, no Homebrew needed npx gitwarren serve # anywhere Node 22.14+ is, including Windows

Then gitwarren serve --open. See The gitwarren command line.

Into a coding agent

If you arrive from a coding agent, start here instead. The plugin brings the MCP server and a note that teaches the agent when to open a review and how to answer your comments:

/plugin marketplace add klarluft/gitwarren-app       # Claude Code, then:

/plugin install gitwarren@gitwarren gemini extensions install https://github.com/klarluft/gitwarren-app npx skills add klarluft/gitwarren-app # the note alone, for any agent

Cursor, Codex, VS Code and Kiro read the same repository from their plugin screens. See Installing it as a plugin.

Contributing

Contributions are welcome. Anything larger than a bug fix starts as a discussion in Ideas, so the shape can be agreed before you spend time on it; once it is settled it becomes an issue. See CONTRIBUTING.md for the development workflow, the two design constraints that changes need to respect, and what a good pull request looks like here.

Before a first contribution can be merged you will be asked to sign the Contributor License Agreement. A bot handles it on your pull request; it takes about ten seconds and only happens once. The CLA keeps copyright in the codebase in one place, which is what makes it possible to offer GitWarren under a commercial licence alongside the GPL, or to change licence later, without having to track down every past contributor. You keep full ownership of your work and can use it elsewhere however you like.

Support and privacy

Questions, ideas and setups worth copying go to Discussions — Q&A if you are stuck on something, Ideas for a feature, and Show and tell for an agent or remote-machine arrangement other people should steal. Bugs you can describe — what GitWarren does, and when — go to issues. Anything you would rather not post publicly goes to contact@klarluft.com.

GitWarren keeps everything on your machine: reviews live in one SQLite file in your application-data directory, the diff is read from your git worktree, and there is no account and no telemetry. The desktop app's one outbound request is the auto-update check against this repository's GitHub Releases. The website's privacy policy covers gitwarren.com itself.

License

GitWarren is free software, licensed under the GNU General Public License, version 3 or (at your option) any later version. The full text is in LICENSE.

In short: you may use, study, modify and redistribute it, including commercially. If you distribute a modified version, or a program that incorporates this one, you must release that under the GPL as well and make the source available. That reciprocity is the point — it keeps GitWarren and anything built on it open.

The copyright is held by Klarluft B.V. (Rotterdam, The Netherlands · KVK 86875590), and every contribution is covered by the CLA. Because the copyright sits in one place rather than being spread across contributors, a licence other than the GPL — for embedding GitWarren in a closed-source product, for instance — can be granted on request: email contact@klarluft.com.

Michal Wrzosek ( ) is the creator of GitWarren and currently its main maintainer.
