DebugBear Website Speed Test

Test page speed and get recommendations to improve load time

Hi everyone,

Our free site speed tool is based on Lighthouse by Google, but adds a ton of custom functionality and debug data:

🌊 Detailed request waterfall showing blocking requests, large images, ... 🔍 Doesn't rely on simulated data like PageSpeed Insights and other Lighthouse-based tools 📹 Rendering filmstrip/video view to see how your website renders

Click on each metric to see how to optimize it. We try to surface the data you need, but if you need help interpreting your results please post a comment and I'll take a look and give some advice!

DebugBear is one of the best tools available today for performance analysis. Running Lighthouse with proper throttling makes a great difference in the accuracy of the data (e.g. as opposed to the data being derived from heuristics which are good if you need the results faster, but can create very incorrect output metrics).

Their team constantly releases fantastic free tools such as this one, the HTML Size analyzer, etc. Fully recommend their work (and definitely recommend checking out the DebugBear product as a whole, it's a really good and flexible tool to integrate on CI/CD pipelines to watch against performance budget regressions).
