19 Chrome Extensions For Web Developers & Designers In 2019

Google Chrome, is without a doubt, the most popular browser in the world. In terms of user share, Google Chrome is well ahead of other major browsers like Mozilla Firefox, Safari, Opera, Microsoft Edge, etc. You can check how other browsers would fare in comparison to Chrome in our blog on the most important browsers for cross browser testing. In just over 10 years, Google Chrome has managed to conquer well over 65% of the market share. One of the key factors behind its meteoric rise is its huge library of extensions that truly sets it apart from the rest, especially for web designers and developers. However, offering a library of extensions as vast as it does, it becomes a bit troublesome for its users to handpick the extensions for their daily needs.

Being a web developer myself, I realize the complete ruckus involved in selecting an extension that could boost my daily basis productivity. It has happened so often that my colleagues refer me some new Chrome extension or two that has drastically helped me deliver better website faster. Looking back I realize, that I have been missing out on these essential Chrome extensions for web developers for months until I was notified by a co-worker. Many times I have helped my colleagues too & I am sure they must be feeling the same way as I did. It is a part of being human when you get to know about something that could have helped you do things faster, you end up saying “If only I knew about it earlier”.

In this article, I am going to highlight meticulously crafted 19 Best Chrome extensions for web developers & designers to boost their productivity and make their lives easier.

1. ColorZilla – Color Picker and Generator

ColorZilla is one of the oldest color picker extension launched over 8 years ago and it has successfully maintained its mantle as the best color picker and an eyedropper Chrome extension for developers or designers even today. ColorZilla will enable you to get a color reading from any pixel on the browser on the fly and paste it in any other program in RGB HEX formats.

Font Face Ninja boasts over 280k downloads and is the direct rival to another popular font face extension called WhatFont.

4. Marmoset – Code Snapshot Generator

Web designers and developers may encounter the need to create snapshots for their codes in their projects for aesthetics or representation purpose. Marmoset is a brilliant Chrome extension that allows you to create beautiful code snapshots in seconds with a single click. This might come in handy for social media posts or Portfolio website designs. It is one of the must-have Chrome extension for web developers & designers.


5. LambdaTest Screenshots – Cross Browser Testing Extension

As a developer, I have often noticed fellow developers missing out on testing what they have built. Sometimes, that careless attitude brings shame to the product, outages bringing discomfort in your office environment. And you feel silly once you get to the root cause of it, and realize that the web application wasn’t working as well for just one browser. This could be due to a deprecated CSS feature, or any other web element that is not so well supported by a browser.

I won’t blame developers for missing out on cross browser testing, as it isn’t feasible when you look at it. Installing multiple browsers, devices, through VMware or any other setup is a hassle for all. This is where LambdaTest comes in handy. LambdaTest provides a cloud-based platform to perform cross browser testing on 2000+ real browsers and browser versions for different devices, so you could end up with an eye-appealing, robust, and cross browser compatible website. For desktop devices, you get to test on both Windows and macOS. For mobile devices, you get to test on both android & iOS.

LambdaTest came up with a Chrome extension to help a user perform automated screenshot testing in bulk. The best part? You can perform screenshot testing across 25 devices in a single go. If you found any UI anomaly then you can share it with your colleagues on your preferred project management tool. Empowering you to perform cross browser testing in a jiffy, LambdaTest Screenshot is certainly one of the best Chrome extensions for developers, designers, and obviously testers, across the world.

6.Page Ruler – Dimension and Size Checker

Page Ruler is one of the most essential and helpful Chrome extension for developers and designers on the list that helps web developers to quickly measure pixel perfect dimensions and positioning of any element on the page. This extension draws out a ruler image on the screen which allows you to inspect individual elements and view their dimension readings – width height along with positioning.

7. Dimensions – Dimension and Size Checker

Another key extension under this category is called Dimensions which helps to measure distances between various elements on a webpage. Its functioning is slightly different from Page Ruler. Dimensions measures distances from mouse pointer up/down and left/right until it reaches a border. This makes it the perfect tool to measure distances between images, input-fields, buttons, videos, gifs, text, icons. Another feature that sets Dimensions apart is its ability to work with mockups as well. If your designer has handed you Page design mockups in Jpeg or PNG formats, drop them inside Chrome and dimensions will work without a hitch. One thing that needs to be noted about dimensions is that it might not always work consistently well with images


8. Check My Links – Broken Link Checker

Check My Links is arguably the most powerful and robust broken link checker Chrome extensions for developers and designers in Chrome library. Check My Links crawls through the entire webpage and validates each individual link and reports whether it is valid or not. Check My Links empowers you to copy every broken link to your clipboard, in only a single click. Identifying and correcting Broken links is critical for any website for effective On-Page SEO and avoiding penalties from Google Site crawlers.

Furthermore, you can even customize how much data you want to clear on the extension option settings – App Cache, Cache, Cookies, Downloads, File Systems, Form Data, History, Indexed DB, Local Storage, Plugin Data, Passwords, and WebSQL. You can either delete cookies globally or for specific domains. One of the handiest Chrome extension for developers, designers, and everyone else too.

10. Wappalyzer – Site Analyser(Technology Identifier)

One of the biggest hurdles that developers face when coming across an impressive website face is the intriguing question – Which technologies have been used to make this website?

11. Ghostery – Privacy Tool

12.JSON Viewer – JSON Beautifier And Viewer

13. Window Resizer – Screen Size Mockup

This extension is a lifesaver for responsive design coding. Although most developers are satisfied with default Chrome dev tools resizer feature, this Chrome extension for developers & designers can simulate any screen size and resolution of all popular devices like iPhones, iPad mac etc. This is quite helpful for developers to test out their layouts on different screen size devices and validate if their responsive media queries coding is working as intended or not.

Keep in mind though, Window Resizer would only be resizing the viewport to provide you with a near about idea of how your website will render on different screen sizes. For a more accurate and thorough responsive testing, you would need real mobile browsers to validate your website rendering.

Other than cross browser testing, LambdaTest also provides responsive testing where you get to visualize your website or web app on real mobile browsers. You can test across 46 mobile devices, both iOS & android, in a single test session.

Corporate Ipsum extension is a special kind of lorem ipsum generator which creates mock business content text. This would make your layouts more visually appealing and presentable to clients.
