Chrome
A list of tools for the Google Chrome browser designed to analyse website speed, to help you optimise your website.
Page Speed for Chrome
Page Speed testing tool from Google available online and with the Google Chrome extension.
Chrome Developer Tools
The inbuilt Chrome developer tools allow you to look deep into a webpage’s CSS, HTML and Javascript coding.
Firebug Lite for Google Chrome
Unfortunately Firebug Lite for Google Chrome doesn’t yet include the Net panel needed for website speed testing, but is still worth an honourable mention.
Speed Tracer
Creates a detailed graph of page-load activity.
Pendule
Although Pendule isn’t specifically a speed testing extension, it allows you to filter out potential coding errors.
