There are a few different ways you can integrate Bootswatch into your project.

Via Pre-compiled Asset

Download the

file associated with a theme and replace Bootstrap's default stylesheet. You must still include Bootstrap's JavaScript file to have functional dropdowns, modals, etc.


You can use the themes via CDN at jsDelivr.

Via Sass Imports

If you're using Sass (SCSS) in your project, you can import the

files for a given theme. This method allows you to override theme variables.
// Your variable overrides go here, e.g.:
// $h1-font-size: 3rem;

@import "bootswatch/dist/[theme]/variables"; @import "bootstrap/scss/bootstrap"; @import "~bootswatch/dist/[theme]/bootswatch";

Make sure to import Bootstrap's

in between

Via npm

You can install as a package with the command

npm install bootswatch

React Users (
, or similar bundler)

Modern JavaScript bundlers (webpack, parcel, rollup) support

ing CSS from JS files. This can make it easier to deploy various 1st and 3rd party assets predictably. Note: There are tradeoffs to the following method, research your tooling before deploying to production.

Before continuing, ensure you've run

npm install bootswatch
in your local project folder. (Use either

Add the following

to your top-level
) file. Add it before any other
import "bootswatch/dist/[theme]/bootstrap.min.css";
// TODO: Note: Replace ^[theme]^ (examples: darkly, slate, cosmo, spacelab, and superhero. See for current theme names.)

Here's an example of updated

to use "slate" theme (using a
fresh project.)
import React from 'react';
import logo from './logo.svg';
import 'bootswatch/dist/slate/bootstrap.min.css'; // Added this :boom:
import './App.css';

function App() { ...

Via Ruby Gem

In your Ruby project, you can access the latest version of each theme by adding the following to your Gemfile and running

bundle install
gem "bootswatch", github: "thomaspark/bootswatch"

Each theme directory is then accessible via the path


Ruby on Rails users can add the following to an initializer (e.g.

Rails.application.config.assets.paths += Gem.loaded_specs["bootswatch"].load_paths

And thus be able to import themes via Sass like so:

@import "[theme]/variables";
@import "~bootstrap/scss/bootstrap";
@import "[theme]/bootswatch";


A simple JSON API is available for integrating your platform with Bootswatch. More info can be found on the Help page.


Bootswatch is open source and you’re welcome to modify the themes.

Each theme consists of two SASS files.

, which is included by default in Bootstrap, allows you to customize the settings.
introduces more extensive structural changes.

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


It's through your contributions that Bootswatch will continue to improve. You can contribute in several ways.

Issues: Provide a detailed report of any bugs you encounter and open an issue on GitHub.

Documentation: If you'd like to fix a typo or beef up the docs, you can fork the project, make your changes, and submit a pull request.

Code: Make a fix and submit it as a pull request. When making changes, it's important to keep the CSS and SASS versions in sync. To do this, be sure to edit the SASS source files for the particular theme first, then run the tasks

grunt swatch
to build the CSS.

Donation: Donations are gratefully accepted via GitHub and PayPal.
