This list of the best Chrome extensions for developers is meticulously curated to enhance your productivity and, most importantly, save you a great deal of time. So if you are a back-end, front-end, or one-man-army web developer, fasten your seatbelts, and let’s go!

"Every great developer you know got there by solving problems they were unqualified to solve until they actually did it."

1. Capture

Chrome rating: 5/5

Capture is the first Chrome extension we advise you to add to your browser for several reasons. With Capture, recording interactions on web pages becomes much easier. It automatically captures all your actions within each test step, generating a timestamped video of your test execution. This video and the transcript of actions allow you to reproduce defects quickly and gain a clear understanding of the reported issues.

It also offers versatile capturing options, including desktop capture, window recording, or in-app screencasting. Capture works even better when everyone on the team uses it. A timestamped video of discovered defects from the testers helps you understand the issue promptly, accelerating the troubleshooting process.

Capture automatically saves crucial information about the operating system, browser version, and window resolution used during the test as well. You can also take full or partial screenshots directly within the browser and annotate them on the spot.

This must-have Chrome extension for web developers also empowers teams with comprehensive test documentation by providing annotated screenshots, timestamped videos, and a log of all tester inputs. As a company, you will save yourself quite a bit of stress that independent and government QA audits often carry. 

Additionally, Capture integrates with one of the most popular bug-reporting tools aqua cloud. With this integration, you can create a test case from scratch, start a test run, and report the captured data directly to the tool.

Capture was designed as a free standalone solution, but what really makes it shine is its tandem work with the popular test management system aqua. Bugs created with Capture become a part of your whole testing ecosystem. aqua brings full visibility and structure to your testing process, unites automated and manual testing seamlessly and empowers it with AI. Created with the idea of saving the QA team’s time and effort by automating manual and repetitive tasks, aqua’s powerful AI capabilities generate requirements & test cases from scratch, identify potential bugs and optimise your whole testing workflow. QA teams report saving up to 73% after switching to aqua, and we think you should do it, too.
