Debug Bar Rewrite Rules is a utility plugin for WordPress that enhances the debugging experience by providing detailed insights into rewrite rules. This plugin serves as an extension of the Debug Bar, but can also function independently as an admin tools page. It offers essential features for developers, such as displaying the number of existing rewrite rules and providing a comprehensive list of both rewrite rules and available filter hooks that can influence them.

In addition to its informative capabilities, Debug Bar Rewrite Rules includes a search function that highlights matches within the rules, allowing for efficient navigation. Users can also test specific URLs to see applicable rules and flush rewrite rules directly from the debug bar panel. This makes it an invaluable tool for WordPress developers looking to optimize their site's performance and troubleshoot issues related to URL rewriting.
