Free Chrome extensions built for developers and QA engineers

This is a small, curated collection of Chrome extensions for the people who spend their day in the browser doing real engineering work — software developers, QA engineers, SDETs and testers. The focus is the testing and API workflow: generating test cases from a feature description, turning captured network traffic into runnable API tests, generating UI and integration test scripts, exploring UIs autonomously, and AI-assisted code review — all without leaving the page.

Every extension is free on the Chrome Web Store and built to do one job well, rather than be a bloated all-in-one platform. Whether you need an AI test case generator, an API testing Chrome extension that writes tests from real traffic, or a way to record and document browser flows, there is a purpose-built tool above. They run in Chrome and any Chromium browser, and new extensions are added regularly.

What you can do with these extensions

Frequently asked questions

Are these Chrome extensions free?
Yes — every extension here is completely free to install from the Chrome Web Store, with no paid tier required to get started.
Which extension generates test cases?
QAtalyst is the AI test case generator — give it a feature, user story or requirement and it produces structured positive, negative and edge-case scenarios. To generate API tests from real network traffic instead, use XHRScribe.
How does the AI API test generator work?
XHRScribe records the XHR and fetch requests your app makes as you use it, then uses AI to turn that captured traffic into runnable API tests — including payloads, headers and assertions — so you don't write them by hand.
Do these extensions work in Edge, Brave or Arc?
Yes — they run in any Chromium-based browser, including Microsoft Edge, Brave, Arc and Opera, in addition to Google Chrome.
Is my data safe?
Each extension requests only the permissions it needs to function. You can review the exact permissions and privacy details on every Chrome Web Store listing before you install.
Who builds Sharaj dev?
Sharaj dev is an independent collection of developer and QA extensions, built and maintained by Sharaj Rewoo and published on the Chrome Web Store.
