Bootswatch is a collection of free themes for Bootstrap. Check it out at


Head over to Bootswatch and download the bootstrap.min.css file associated with a theme. Replace Bootstrap's stylesheet with this file.

The themes are also hosted on BootstrapCDN.

For use with Rails, check out bootswatch-rails (Sass) and twitter-bootswatch-rails (LESS). For use with a Yeoman app or with Bower check out bootswatch-scss.


Bootswatch is an open source project, and you’re welcome to fork and modify the themes.

Each raw theme consists of two LESS files. One is variables.less, which is included by default in Bootstrap and allows you to customize these settings. The other is called bootswatch.less and introduces more extensive structural changes.

Check out the Help page for more details on building your own theme.


A simple API is available for integrating your platform with Bootswatch.

The swatch objects are housed in an array called themes, and each swatch has the following properties: name, description, preview, thumbnail, css, cssMin, less, and lessVariables.

CORS and JSONP are supported. Send your request to
