Chrome extensions are one of the ways to boost daily basis productivity and optimize development workflow.
I've collected a list of my favorite, most used Chrome extensions that can make you a more productive developer.

1.30 Seconds of Knowledge

Each time you open a new tab you, you get a random code snippet. There are 9 Categories of snippets, consisting of Programming Languages, Frameworks & Interview Questions.
This is an excellent extension not only for newbie developers.

2.Axe Web Accessibility

Axe is ideal for developers to test Web applications to help resolve accessibility issues. Find violations against common standards including WCAG 2.0 A/AA or Section 508.




Lighthouse is a popular must-have extension for developers. It does a full audit of the web site along 5 dimensions: performance, accessibility, best practices, SEO, and whether you have a Progressive Web App.




My one of the most favorite extensions. ColorZilla includes a Color Picker, Eye Dropper, Gradient Generator and many more advanced color tools.




Wappalyzer is a cross-platform utility that uncovers the technologies used on websites. It detects content management systems, e-commerce platforms, web frameworks, server software, analytics tools and many more.

This is a very helpful tool for non-native speakers of English like me and not only.
Grammarly is a writing assistant that goes deeper than grammar to offer you comprehensive writing feedback. You can be confident that your writing is not only correct but clear and concise, too.

14.Window Resizer

The extension re-sizes the browser’s window to emulate various resolutions. It is very useful for web designers and developers by helping them test their layouts on different browser resolutions.

I also use the following extensions:


Gmail Checker

Vue Devtools



At the moment there are 25 extensions on my Chrome and all are useful for everyday life and work. It’s true they make Chrome a bit slower but I would not remove any of them.

Editor guide

I'm using Kontrast as for wcag/color-picker/contrast-checker. It's awesome!



Wow, it's amazing, thank you! I used this web page to check contrast ratio but the extension is much faster and handy <3


Yeah I used different web pages as well before, this extension is so much better! Glad I could help :D


Wappalyzer was a gem! Thanks for sharing the info!
I would also add ChromeVox to the list.


Thank you, will check it!:)


I'd add page ruler and my favourite Tampermonkey, first one lets you measure width and height in your screen and second one lets you attach custom scripts to pages. So basically you are writing chrome extension by yourself very easily. It's very productive


Added both:) Tampermonkey seems very interesting, thank you


Add to your list an extension for showing file tree in github - Octotree.


Thank you!:)


30 seconds of knowledge sounds cool


You should try Daily. It's a great application that allows you to gather a lot of development related articles in one place. The app is convenient, simple and looks great.


Wow, it looks amazing, thank you! Added:)


What makes Window Resizer better than just using the one in Chrome DevTools?


It's just my personal choice, I find it handier:)


Why use colorzilla? You can pick colors using the built-in dev tools right?


Maybe I'm lazy and prefer to get colors just by one click:)
