GitHub Code Counter is a Chrome extension designed to provide instant analytics of code within GitHub repositories. This tool allows users to count the total lines of code in any public repository and offers a detailed breakdown by file extension. It also supports the exclusion of specific file types from the analysis, making it versatile for various coding projects. Users can add their personal GitHub token to analyze private repositories and benefit from cached results for quicker subsequent analyses.

The extension is lightweight and requires minimal permissions, ensuring a seamless integration into the browsing experience. To use GitHub Code Counter, simply navigate to a GitHub repository and click the extension icon in the toolbar. Security is prioritized as the GitHub token is stored locally and expires after one hour, with no data sent to external servers. This makes it an ideal tool for developers and team leads looking to gain insights into codebase size and composition.
