Windi CSS

Windi CSS was an on-demand, utility-first CSS framework designed as a performant alternative to Tailwind CSS, aiming to address compilation speed issues in larger projects by providing quicker hot module replacement (HMR) and eliminating the need for production purging. It dynamically scanned HTML and CSS to generate utilities. The project officially announced its deprecation in March 2022, recommending users migrate to Tailwind CSS v3 or newer. While its last stable version, 3.5.6, included some Tailwind v3 utility classes and bug fixes, no further active development, new features, or security updates are expected. Key differentiators during its active period included its 'on-demand' compilation approach and extensive framework integrations.
