Sass.js

Sass parser in JavaScript. Have a look at the Interactive Playground to play around with compiling SCSS to CSS in your browser.

This is a convenience API for emscripted libsass (at v3.5.4). If you're looking to run Sass in node, you're probably looking for node-sass. Sass.js and node-sass should generate the same results.

A fair warning: minified the worker weighs 3.5MB, gzipped it's still 752KB. If you're on NodeJS, please use the (considerably faster) node-sass instead.
