The developer tools panel for WordPress
Query Monitor is a plugin that enables you to inspect and debug many aspects of your site, including:
- Database queries
- PHP errors
- Hooks and actions
- Scripts and styles
- Theme template files
- Translations
- Rewrite rules
- Block editor blocks
- HTTP API calls
- and much more…
Query Monitor focuses on presenting information in a useful manner, for example by showing database queries grouped by the plugins, themes, or functions that are responsible for them. This allows you to efficiently determine which plugins, themes, or functions are performing poorly.
Query Monitor is free and open source software, just like WordPress. It’s also bundled by default on some of the most high-trafficked WordPress platforms in the world, including Altis and WordPress.com VIP.
