Rewrite Rules Inspector

A simple WordPress admin tool for inspecting rewrite rules. View a listing of all your rewrite rules, see which rewrite rules match a given URL (and the priorities they match in), or filter by different sources of rewrite rules. Perform a soft flush of your rewrite rules to regenerate them.

Developed on GitHub — pull requests are always welcome. Please leave feedback, questions, bug reports, and feature requests in the GitHub issues.

Where to find it

Go to Tools → Rewrite Rules in the WordPress admin.

URL Tester

Quickly test any URL (or path) against your site’s rewrite rules:

• See whether the URL would be a 404 or which rule would match first (the one WordPress uses).
• View the list of all matching rules, in match priority order.
• Inspect the query variables extracted from the match and the resulting final query WordPress would run.

Works with full URLs or paths and automatically handles sites installed in a subdirectory.

Permastructs

Browse a table of all permastructs that WordPress is aware of, including:

• Name — the permastruct key (e.g. for posts, taxonomies, authors).
• Structure — the permalink structure pattern used to generate rules.
• Description — a human-friendly summary of what the permastruct controls.
