*header pic by Shen Comix

Developers spend a lot of time using browsers. As of February 2021, 63% of worldwide Internet users prefer Google Chrome over other web browsers. And it’s not surprising because Google Chrome boasts its wide collection of extensions that extend browser functionality. So instead of installing additional software and tools, you can create your personal extensions toolkit that you can take with you wherever you go – just log into your Google account on any other device with pre-installed Google Chrome and sync the data.

We asked our developers at actiTIME to share their favorite Google Chrome extensions that they use on a daily basis and compiled this comprehensive collection of development and productivity extensions. Save this list to get back to it anytime.
