Query Monitor is a WordPress and WooCommerce plugin that adds a developer tools panel for debugging database queries, PHP errors, hooks, blocks, enqueued assets, and HTTP API calls. It aggregates and filters its output by plugin, theme, or function to help identify poorly performing components.

Use cases

• debug slow WordPress page loads
• find which plugin is making the most database queries
• track down PHP warnings and deprecated function usage
• inspect hooks and action callbacks during a request
• debug Ajax and REST API calls
• identify slow or duplicate SQL queries
• see which template files and blocks render on a page

When to choose

• you develop or maintain WordPress or WooCommerce sites and need in-request debugging
• you need to attribute performance problems to specific plugins, themes, or functions
• you want a free, enterprise-trusted profiling tool on WordPress VIP or similar platforms

When to avoid

• you need historical or cross-request performance monitoring rather than per-page-load data
• your stack is not WordPress-based
• you need application performance monitoring in production for all users rather than admin-only debugging
