Rewrite Rules Inspector is a simple development tool for viewing all of the rewrite rules registered with your site. It’s been available for VIPs hosted on WordPress.com for a while — today it’s available for download from the WordPress.org repository.

Specifically, the Rewrite Rules Inspector helps you:

• View a listing of all your rewrite rules.
• See which rewrite rules match a given URL (and the priorities they match in).
• Filter by different sources of rewrite rules.
• Know when rewrite rules are missing in the database by showing an error message.

Do fork the plugin in Github — pull requests are always welcome. Hit us with feedback, questions, bug reports, and feature requests in the forums.
