A cross-platform desktop app for doing local code reviews of your own git repositories. Single user, single machine, no server, 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.
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.
The part that makes it worth having: a review can include work that has not been committed. 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. You can review a change before it is a commit, which is exactly when review is most useful.
Nothing is cached: every branch name, commit and diff on screen is read from git at the moment it is shown.
Local AI agents get the same capabilities through an MCP server over stdio.
