In their own words
BackstopJS
BackstopJS is a free, MIT-licensed tool for visual regression testing of web applications. It captures screenshots and compares them with reference images over time. An in-browser report shows reference, test and visual-difference views, with additional CLI and JUnit reports. BackstopJS supports Puppeteer and Playwright; Playwright can use Chromium, Firefox or WebKit. Scenarios can script clicks, scrolling, hovering, key presses and cookie state. Captures can cover a full document, viewport or selected DOM elements at configured viewport sizes. The documented workflow uses `backstop init`, `backstop test` and `backstop approve` to configure tests, compare captures and update references. Installation works globally or locally through npm, as a standalone CLI or from a Node.js app. CI reporting and integrations include Jenkins, Travis and gulp. Docker can reduce rendering differences, though Chrome Headless in Docker needs substantial memory.
