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 priorites they match in).
- Filter by different sources of rewrite rules.
- Know when rewrite rules are missing in the database by showing an error message.
