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.
