Wallace CLI is a command-line tool for analyzing CSS files and generating pretty analytics in the terminal. It provides statistics like number of rules, selectors, declarations, specificities, and more. The current stable version is 4.0.2, released occasionally. It is part of the Project Wallace ecosystem and is powered by the CSS Analyzer library. Unlike other CSS analysis tools, Wallace CLI offers a colorful table output and JSON format, making it easy to integrate into build pipelines. It requires Node.js >=20.12.0 and is designed for developers who want quick CSS quality insights from the terminal.
