Merge Guardian is a free Chrome add-on developed by kmlprtsng. It falls under the category of Browsers and specifically belongs to the Add-ons & Tools subcategory. This add-on serves the purpose of disabling the merge button on Bitbucket PR's commit message if a certain keyword is missing.

The main motivation behind the creation of Merge Guardian was to address the need for a way to prevent the merge button from being disabled when a specific keyword was missing from the commit message of a PR on Bitbucket. As Jenkins required this functionality, and Bitbucket lacked a built-in solution, this extension was developed to bridge the gap. The beauty of Merge Guardian lies in its configurability, allowing users to define their own keywords according to their requirements.
