framer.js

You need the potential to design something completely new. Prototyping shouldn’t limit you. Framer is a prototyping tool that uses code to make anything possible.


Pure

  • Pure is ridiculously tiny. The entire set of modules clocks in at 4.5KB* minified and gzipped. Crafted with mobile devices in mind, it was important to us to keep our file sizes small, and every line of CSS was carefully considered.

Foundation

  • Responsive design gets a whole lot faster for users.
  • Crazy fast for designers and engineers to code and learn too.

Bootstrap

  • The most popular front-end framework for developing responsive, mobile first projects on the web.
