The 17 Best Google Chrome Extensions for Web Developers

The 17 Best Google Chrome Extensions for Web Developers

Though it may seem like forever, Google Chrome has only been around since 2008. Regardless, in its 10 short years, Google Chrome has become the most used and most popular web browser of all web browsers available.

Although Chrome hasn’t ever matched (or bested) the same popularity Internet Explorer (IE) once enjoyed in the early days of the internet (IE had an upwards of 90% market share then, Chrome has 53.9%), it still beats out most of the other browsers on the market by a mile. And even those who once hitched their (digital) wagons to IE have since switched to Google Chrome because it is fast, simple to use, and chock full of features and add-ons like extensions and themes.

As a web developer, you want to be sure that what you’ve designed is able to adapt to any device or browser. As a start, Google Chrome (the most used browser), should be at the top of that list. But besides using Chrome as part of your browser testing, it’s also helpful in terms of the tools (or extensions) that were specifically created for web developers.

Here are some of the best Google Chrome extensions for web developers.

General Tool: Web Developer
