BackStopJS - how to avoid visual regression of our web application?

BackStopJS is a tool that helps prevent visual regression by taking screenshots of web pages and comparing them pixel-by-pixel across runs to detect changes. It is an open source NPM package that uses Chrome/Puppeteer to capture screenshots, generates HTML and JUnit reports, and supports parallel testing. BackStopJS is easy to set up and use, but is not well-suited for dynamic content. While other commercial tools like Applitools may integrate better with UI tests, BackStopJS provides a free and simple way to start visual regression testing.
