Speedlyst - Web Speed Analytics

Google PageSpeed Insights shows what your visitors experience. Speedlyst adds local WordPress diagnostics to help you understand what may be causing the problem. Measure mobile PageSpeed Insights and Core Web Vitals, check the health and performance of WordPress itself, follow changes over time, and export everything into one AI-ready report. Speedlyst helps you diagnose:

• Core Web Vitals and mobile PageSpeed performance
• PHP memory usage and limits
• Object cache and OPcache
• Autoloaded options and database overhead
• WP-Cron delays
• WordPress admin performance
• Changes and trends over time

No Google API key, account, or registration is required. Speedlyst measures and diagnoses performance. It does not modify, cache, or optimise your website automatically. This plugin is an independent project and is not affiliated with, endorsed by, or sponsored by Google LLC.
