Local-only code review for your git repositories. Your code, your diffs and your comments stay on your machine — there is no server, no account and nothing to sign in to.

This package is the command line. There is also a desktop app; see gitwarren-app.

npx gitwarren serve

That serves the review UI on 127.0.0.1:41427 and prints a URL carrying a token minted for that launch. Open it, add a repository, pick two refs, and review the diff.

Commands


`gitwarren serve`	serve the web view on loopback and print its URL
`gitwarren serve --stdio`	answer GitWarren's protocol on stdin/stdout
`gitwarren open [link]`	open this machine's GitWarren in a browser, carrying the token
`gitwarren service install`	write the agent launcher, and start at login
`gitwarren service uninstall`	remove the login item
`gitwarren service status`	what is registered, and what is running

gitwarren open takes a gitwarren:// deep link or the http://127.0.0.1 URL an agent hands out, and lands on that review rather than the home screen.

Letting an agent in

gitwarren service install writes ~/.gitwarren/bin/gitwarren-mcp, which is a GitWarren MCP server your coding agent can start. Point the agent at that one path — it is the same on every machine, and GitWarren keeps it pointing at whichever install ran last.

Where your data is

One SQLite database in the usual place for your platform — ~/Library/Application Support/GitWarren on macOS, ~/.config/GitWarren on Linux, %APPDATA%\GitWarren on Windows. gitwarren service status prints the path.

The web view binds 127.0.0.1 only, checks Host and Origin on every request and on the WebSocket upgrade, and requires a token minted per launch which it exchanges for a SameSite=Strict cookie. A page on another origin cannot reach it.
