GitBaz is a free Chrome extension designed to enrich the GitHub user experience by providing valuable contributor context directly on GitHub pages. It offers features such as Contributor Scores, which evaluate contributors based on PRs, commits, and other metrics, as well as Smart Badges that highlight user achievements like 'First-Timer' and 'Veteran.' Users can easily access PR and issue context, discussion panels, and even bus factor analysis to assess the risk of relying on single contributors.

In addition to these features, GitBaz includes tools for visualizing contributor activity through heatmaps, detecting bot accounts, and identifying AI-generated pull requests. The integration with OpenSSF Scorecard enhances repository security analysis. Notably, GitBaz prioritizes user privacy by ensuring that all data remains local to the user's browser, with no external tracking or analytics. The setup process is straightforward, requiring users to install the extension and configure their GitHub access token.
