Blaze UI is a free & open-source (MIT Licence) Framework with a lightweight UI Toolkit that provides a great structure for building websites quickly with a scalable and maintainable foundation.

Blaze is a powerful library for creating user interfaces by writing reactive HTML templates. Compared to using a combination of traditional templates and jQuery, Blaze eliminates the need for all the update logic  in your app that listens for data changes and manipulates the DOM.
