It provides a wide range of components and utilities similar to GOV.UK Frontend but is more general-purpose and not specifically tailored to government services.
Foundation is another front-end framework that offers a variety of responsive components and styles. Like Bootstrap, it is a general-purpose framework and does not specifically adhere to government design principles.
The U.S. Web Design System (USWDS) provides a set of design guidelines and components for building accessible and consistent government websites in the United States. It is similar to GOV.UK Frontend but tailored to U.S. government standards.

There are 2 ways to start using GOV.UK Frontend in your app.
Once installed, you will be able to use the code from the examples in the GOV.UK Design System in your service.
We recommend installing GOV.UK Frontend using node package manager (npm).
You can also download the compiled and minified assets (CSS, JavaScript) from GitHub.
You need to import the GOV.UK Frontend styles into the main Sass file in your project. You should place the below code before your own Sass rules (or Sass imports) if you want to override GOV.UK Frontend with your own styles.
To import add the below to your Sass file:
@import "node_modules/govuk-frontend/dist/govuk/all";
More details on importing styles
Some of the JavaScript included in GOV.UK Frontend improves the usability and accessibility of the components. You should make sure that you are importing and initialising JavaScript in your application. This will ensure all users can use it successfully.
You can include JavaScript for all components by copying both govuk-frontend.min.js and govuk-frontend.min.js.map from node_modules/govuk-frontend/dist/govuk/ into your application and referencing the JavaScript directly:
<script type="module" src="{path-to-javascript}/govuk-frontend.min.js"></script>
Next you need to import and initialise GOV.UK Frontend by adding:
<script type="module">
import { initAll } from '{path-to-javascript}/govuk-frontend.min.js'
initAll()
</script>

In order to import GOV.UK Frontend images and fonts to your project, you should configure your application to reference or copy the relevant GOV.UK Frontend assets.

v5.5.0 (Feature release)
To install this version with npm, run npm install govuk-frontend@5.5.0. You can also find more information about how to stay up to date in our documentation.
We've overhauled the list of organisations and organisation brand colours that are shipped with GOV.UK Frontend.
The previous list was outdated and had not kept up with changes to the machinery of government. We’ve updated the list to:
To enable these changes, set the feature flag variable $govuk-new-organisation-colours to true before you import GOV.UK Frontend in your Sass files:
// application.scss
$govuk-new-organisation-colours: true;
@import "govuk-frontend/all";
You can also silence warnings about defunct organisations by adding organisation-colours to the $govuk-suppressed-warnings setting.
We introduced this change in pull request #3407: Update organisation colours.
govuk-!-text-break-wordWe've added a new override class to help display long words with no obvious break points when the space is too narrow to display them on one line. An example of a long word might be an email address entered by a user.
Wrapping the content with the govuk-!-text-break-word class forces words that are too long for the parent element to break onto a new line.
A confirmation email will be sent to <span class="govuk-!-text-break-word">arthur_phillip_dent.42@peoplepersonalitydivision.siriuscyberneticscorporation.corp</span>.
Sass users can also use the govuk-text-break-word mixin.
We introduced this change in pull request #5159: Add break-word typography helper.
$websafe parameter on the govuk-organisation-colour functionThe govuk-organisation-colour Sass function's $websafe parameter has been renamed to $contrast-safe.
This is to more accurately describe the functionality of the parameter.
The old parameter name will stop working in the next major version of GOV.UK Frontend.
We introduced this change in pull request #3407: Update organisation colours.
