Webjoule is the metric for measuring the energy consumed by a web page. It corresponds to the joules consumed by a web page from Time To First Byte (TTFB) to Time To Interactive (TTI).
We believe that to do something well you have to focus on a very specific area. That's why we decided to measure the power consumption of the software on the CPU, because we believe that this is the focus of consumption and that the software manufacturers themselves can improve.
We analyse the energy consumption of software in a revolutionary way. We can quickly and accurately recognise the javascript, css and HTML code blocks contained in pages and give a weight to each according to their usage and location.
It is very important to monitor and improve your CO2 emissions included in the Scope 3 section of ESG reporting derived from the energy consumption of devices using your services.

We use an empirical approach to validate the result of our software using an objective hardware measurement for comparison, helped by professionals and researchers, following these studies as guideline:
This tool is constantly evolving. Our mission is to measure each type of web page in the best possible way. At the moment, we are not able to measure PWAs and highly interactive WebApps correctly, just as we cannot provide details on the amount of data transmitted by streaming services.
