There are hundreds of Chrome Extensions available to make your browsing and development experience easier. I’m not going to concentrate on the end user experience here – instead I’ll point out the kind of tools that make my life easier as a developer. Tools that allow me to get information faster, to diagnose problems and to deliver better product to my clients.

In this post I’ve split the Chrome Extensions up into the following categories:

  • Search Engine Optimisation (SEO)
  • Accessibility
  • Design Tools
  • Developer Tools

Page Ruler by wrakky

This Chrome Extension lets you draw a ruler to get pixel dimensions and positioning, and measure elements on any web page.  It displays the width, height and position.

This might not seem much, but if you’re trying to grab a layout or find the the width of a column, it’s invaluable.

Fontface Ninja

Fontface Ninja is a Chrome Extension you can install in your browser to recognize, try, and download any font on the Internet.

Select any line of text that appears on a web page, roll over it with FontFace Ninja activated, and it gives you the name, size and line spacing.

Web Developer toolbar by Chris Pederick

I’ve used this extension in Chrome and Firefox for ages. I couldn’t do my job without it.

Adds a toolbar button with various web developer tools. From HTML and CSS validation, to outlining, responsive testing, plugin and code framework disabling/enabling, this Chrome Extension is immensely powerful.

Adobe Edge Inspect by Adobe

Although it’s not really just a Chrome Extension, but more a combination of Desktop Application, Device Application and Chrome Extension, Adobe Edge Inspect allows you to see how your website truly appear and perform on mobile devices.

Edge Inspect is an essential application for web developers and designers who need to preview their content across multiple mobile devices. Wirelessly pair multiple iOS and Android devices to your computer, grab screenshots from any connected device, and see real-time results from changes to HTML, CSS, and JavaScript.

It also allows you to display and debug your device-centric code very easily.
