We’ve compiled this list of thirty amazing resources for Sass. In it you’ll find all kinds of goodies built on and for Sass: frameworks, plugins, apps and a lot more.
Frameworks and Grid Systems
1. Compass
Sass is an extension of CSS3 which adds nested rules, variables, mixins, selector inheritance, and more. Sass generates well formatted CSS and makes your stylesheets easier to organize and maintain.
2. Bourbon Sass Mixins Library
A simple and lightweight mixin library for Sass. After Compass, it’s definitely one of the better Sass mixin libraries that we’ve found.
3. Bourbon Neat
A lightweight semantic grid framework for Sass and Bourbon. It’s super simple and fully responsive.
4. Foundation
Foundation is the main competitor to Twitter Bootstrap. Bootstrap is built on LESS while Foundation is built on Sass.
5. Bootstrap Sass
Bootstrap-sass is an Sass-powered version of Twitter's Bootstrap, ready to drop right into your Sass powered applications.
6. Animate.sass
Animate.sass is a Sass and Compass CSS animation library for WebKit, Firefox and beyond based on the work being done by Dan Eden in Animate.css. The core of Animate.sass, despite being named "dot sass", is written in SCSS.
7. Forge
Forge is a free command-line toolkit for bootstrapping and developing WordPress themes in a tidy environment using front-end languages like Sass, LESS, and CoffeeScript.
8. Skeleton-SASS
Skeleton-SASS is a one-to-one translation of the classes in Skeleton's grid framework, but remixed as SASS mixins. Instead of giving a div a class of six columns, inside your own CSS specifying the div you'd simply include the mixin +columns(6).
The other big advantage of Skeleton-SASS is that the actual grid widths are only calculated at compile-time. This means that your page width, number of columns, and margin sizes are all easily tweakable if you want to mix things up —- say, switch from a 16-column grid to a 24-column, or bump everything up to 1024px instead of 960px.
9. Susy: Responsive grids for Compass
Susy is based on Natalie Downe's CSS Systems, made possible by Sass, and made easy with Compass. You can use it anywhere, from static sites to Django, Rails, Wordpress and more.

11. Frameless
Frameless is as a suggestion for a new way to structure your grids. Frameless isn’t completely Sass focused, but there is a Sass template to get you started.
12. Zen Grids
Writing your layout in Sass with Zen Grids is easy. With the verboseness of properties and values like margin, padding, floats, and clears, CSS actually gets in the way of figuring out how to layout our content.
13. BlankWork – Flexible SASS Gridsystem
Blankwork allows you to have a wrapper, container and columns at the moment.
14. 320 and Up
