Flat UI Free

Flat UI is a beautiful theme for Bootstrap. We have redesigned many of its components to look flat in every pixel.

To get started, check out getting started page or follow instructions below.


Quick start

Three quick start options are available:

Run npm install and bower install to install dependencies.

Read the getting started page for information on the framework contents.
