Code Profiler Pro

Code Profiler Pro measures work in the PHP code WordPress runs on your server. Charts and tables show extension and theme performance, with Pro profiling that can trace activity to PHP scripts, classes, methods, and functions. This helps you locate where a slow process needs investigation. Browser-based page speed utilities measure a page from the user’s browser perspective.

Choose a workflow to profile

Run a profile on the WordPress frontend or backend, a cron event, or a custom URL. GET and POST methods, custom cookies, and HTTP headers let you examine requests such as contact form submissions, checkout processes, and AJAX actions.

Inspect code and related activity

Pro adds profiling for PHP scripts, methods, and functions. It also reports database query performance and monitors remote connections. Profiles include file I/O operations and statistics, plus disk I/O usage. Filters help you focus on relevant results.

Review and export profile results

Export charts as PNG images. Pro can export tables and charts in CSV format, and WP-CLI offers another way to execute the profiler. You can leave Code Profiler active between sessions without affecting site performance.
