9 Exciting Open Source Sass Frameworks

Every CSS developer should know about Sass to see what it offers. This superset of CSS has revolutionized stylesheets much like jQuery revolutionized JavaScript.

And alongside many CSS UI frameworks we also have SCSS/Sass frontend frameworks. Most of these are pretty new but gaining traction quickly.

We’ve curated 9 of the best free SCSS frameworks here so if you’re a Sass user then you’ll definitely want to check these out.

1. Sierra

The Sierra framework is touted as one of the lightest and smallest SCSS frameworks on the market. Currently in v2.0 it weighs a total of 37KB.

This may not be literally the smallest option out there, but even the minified Bootstrap stylesheet totals ~120KB so Sierra is pretty light. It’s also well organized with separate files for mixins, buttons, tables, typography, and other common page elements.

This file separation is standard for Sass development and it makes your job much easier when customizing the framework.

You’ll find a complete live demo with all the main elements on Sierra’s main page along with setup documentation on GitHub. I’d rate this in the top three of all Sass frameworks so it’s definitely worth a look if you’re curious.
