GitHub Merge Guardian is a Chrome extension developed by daku10. It falls under the category of Browsers and belongs to the subcategory of Add-ons & Tools. This free extension is designed to prevent incorrect merges on GitHub's pull request page.

With GitHub Merge Guardian, users can easily control the merge method for pull requests by adding configurations based on the combination of repositories and branches. Each configuration consists of the repository name, base branch, compare branch, and merge strategy. The wildcard character (*) can be used in each item for added flexibility.

When a configuration matches, the color of the merge button changes, alerting users to potential incorrect merges. However, the extension only changes the button color and still allows merges with strategies other than the specified one.

One of the key features of GitHub Merge Guardian is its customizability. Users have the option to customize the color of the merge button according to their preference.
