Check for free the load time of each element of a page and know which ones are lowering your performance.

Start using our payload analyzer


Analyze your page load times

Evaluate the time needed between a user request, the moment the page is fully rendered in the browser and analyze what is slowing down the process with timing details per linked resource.

Inspect HTTP headers

For each resource, from the main page to every linked asset (JS, CSS, Media, etc), check if the HTTP headers meet your expectations (cacheability, activated compression, …) and increase your user’s navigation.

Optimize your resources

Using all the insights provided (resources size, load times and headers), find what is slowing down the rendering process and take action to leverage it. Earn points regarding bots paying attention to the bandwidth and load times required to analyze your website.
