VC GitHub Lookup — Startup Signals on Hover is a Chrome extension designed to provide valuable insights into GitHub repositories and organizations. By hovering over any GitHub repo or org, users can access vital VC-grade engineering signals such as commit velocity, contributor growth, and breakout status. This tool transforms GitHub into a deal-flow surface, allowing investors and engineering leads to identify promising startups quickly. Key features include commit velocity over the last 14 days, velocity changes, contributor count, and engineering signal types like hiring bursts and reorganizations.

The extension also integrates seamlessly with GitHub, injecting a data chip next to the page header for easy access. Users can manually look up any GitHub organization or URL through the toolbar icon. Notably, the extension prioritizes user privacy by not tracking or collecting personal data, with all data sourced from GitDealFlow's public sector rankings. For a comprehensive analysis, users can also install the companion extension, "VC Deal Flow Signal," which provides similar insights on Crunchbase and Wellfound profiles.
