squint

Squint is a CLI tool designed for visual regression testing of web applications, enabling users to compare production and beta versions by automatically crawling URLs and taking screenshots of web pages using Puppeteer. It outputs visual diffs for pages with discrepancies, while offering configurable CLI options for advanced users, such as the ability to connect to existing Chrome sessions and customize pre-screenshot scripts. Notable features include smart defaults, cross-platform compatibility, and the capacity to handle specific use cases like single-page comparisons and element-specific diffing.
