Sitespeed.io - how speedy is your website?

Sitespeed.io is an open source tool that helps you analyze and optimize your website speed and performance, based on performance best practices rules.

What do sitespeed.io do?

You give sitespeed a start point, the first page on your site, where you want it to start crawl. By default, one level will be crawled, meaning all links (on the same domain as the main page), will be fetched & analyzed.

The flow looks something like this:
