Welcome to the wonderful world of web performance!

sitespeed.io can:

• analyze your site against web performance best practice rules, crawl your site or test specific URL:s
• measure how fast your site/pages is using the [Navigation Timing API] (http://www.w3.org/TR/navigation-timing/) and [User Timing API] (http://www.w3.org/TR/user-timing/)
• send all your metrics to Graphite
• benchmark your site against your competitors (comparing specific pages, creating reports, dump the data to Graphite)
• drive WebPageTest (WPT), meaning collect metrics from WPT, create reports and or send the data to Graphite
• test your site against your performance budget
• output TAP or JUnit XML to run in your Continuous Integration tool
• create configurable HTML reports
• test your site against [Google Page Speed Insights] (https://developers.google.com/speed/pagespeed/insights/) and include the result in the reports
• create your own post task that will get the result from the analyze and do whatever you want with it (store to a database, create new reports etc)

$ npm install -g sitespeed.io
