Sitespeed.io is an open source tool that helps you analyze your website speed and performance based on performance best practices and metrics. It collects data from multiple pages on your website, analyze the pages using the rules and output the result as HTML or send the metrics to Graphite.
You can analyze one site, analyze and compare multiple sites or let it run in your CI tool and break build if your site doesn't meet your speed needs.
