ReviewIt is a lightweight, zero-configuration command-line tool designed for efficient code review. It spins up a local web server to display Git commit diffs in a GitHub-like "Files changed" view, catering to developers seeking a streamlined review process without leaving their terminal. The tool also offers an integrated commenting system and prompts for AI code assistants like Claude.

How It Works

ReviewIt leverages a Node.js backend powered by Express and Commander.js for CLI argument parsing. It uses simple-git to process Git diffs and Octokit for GitHub API interactions, enabling review of local commits, branches, or remote pull requests. The frontend is built with React 18, TypeScript, and Vite, featuring Tailwind CSS for styling and Prism.js for syntax highlighting, which is dynamically loaded based on file extensions for performance.

Limitations & Caveats

The "working" keyword for diffs does not support a compare-with argument. While public repositories can be reviewed without authentication, they are subject to rate limits.
