Welcome to the wonderful world of web performance!

Using sitespeed.io you can:

Test your web site against Web Performance best practices using the Coach.
Collect Navigation Timing API, User Timing API and Visual Metrics from Firefox/Chrome using Browsertime.
Run your custom-made JavaScript and collect whichever metric(s) you need.
Test one or multiple pages, across one or many runs to get more-accurate metrics.
Create HTML-result pages or store the metrics in Graphite.
Write your own plugins that can do whatever tests you want/need.

See all the latest changes in the Changelog.

If you use Firefox 55 (or later) please have a look at https://github.com/sitespeedio/browsertime/issues/358. When 57 is released we think there will be a easy way to fix it :)
