Git Diff Stats is a Chrome extension developed by luanab97silva that allows users to inject pull request diff stats into GitHub, GitLab, and BitBucket pull request lists. With this extension, users can avoid the need to open each pull/merge request to assess its size, as the diff stats of each pull/merge request are directly visualized on the list page.

The diff stats provided by Git Diff Stats include the number of files changed, lines added, and lines deleted. This information gives users a quick overview of the changes made in each pull/merge request, allowing for easier and more efficient code review.

To activate the extension for GitHub, GitLab, or BitBucket, users need to provide their respective credentials in the extension's options. These credentials are personal access tokens generated by the user with the necessary permissions for the extension. It's important to note that these credentials are stored locally in the browser's persistent storage and the extension does not collect any user data.
