The coach helps you find performance problems on your web page. Think of the coach as a modern version of YSlow. The coach will give advice of how your page can be faster.

  • The coach gives you advice on how to make your page faster. The coach aims to NEVER give you bad advice. Follow the advice and you will WIN!
  • HTTP/1 or HTTP/2? That's no problem, the coach adjust the advice accordingly.
  • The coach uses real browsers to see your page exactly like your users do.
  • Every advice has one or more unit-tests to make sure it's easy to change advice in the future.
  • The coach knows about more than just performance: Accessibility and web best practice are other things that the coach can help you with.
  • You can integrate the coach with your own web performance tool. It's easy: your tool only need to be able to run JavaScript in the browser and produce a HAR file. Or you can use the built-in functionality of the coach to run the browser.
  • The coach is open-source. The advice is public, you can check it and change it yourself. Help us make the coach even better!
  • The coach can combine knowledge from the DOM with HAR to give you super powerful advice.
  • The CLI output is pretty nice. You can configure how much you want to see. Use it as fast way to check the performance of your page.
  • The coach will be part of sitespeed.io 4.0 and it will be awesome!
