Quick Start

Introduction and Tutorial

Keycloakify is a tool for creating custom Keycloak themes, enabling you to modify the appearance and behavior of Keycloak's user interfaces. This includes:

• Login Theme: The UI for login and registration pages, displayed to users when they attempt to log in or sign up.

• Account Theme: The account management interface, where users can update their email, change their password, and manage other account settings.

• Email Theme: The templates used by Keycloak for automated emails, such as email confirmation or password reset notifications.

• Admin Theme: The Admin Console interface, used by administrators to configure Keycloak.

For a visual preview of these UIs as they appear with Keycloak's built-in theme, visit the Storybook demonstration:

Whether you need to apply light CSS-level customizations to the built-in UIs or perform deeper redesigns at the component level using React, Angular, or Svelte, Keycloakify is the tool to achieve your goals. If you’d like to see Keycloakify in action, check out Neon. Clicking Login or Sign Up will take you to their Keycloakify-themed login pages.

Why Choose Keycloakify?

You might be wondering why you would need a third-party tool like Keycloakify to create your custom UIs instead of relying solely on Keycloak's built-in theming system. Here are a few reasons:

• Leverage Modern Frontend Technologies: Keycloakify enables you to use TypeScript, React, Angular, Svelte, and any styling solution or component library you prefer, such as Tailwind, MUI, shadcn/ui, or plain CSS.

• Streamlined Testing: Keycloakify makes it easy to test your theme both inside and outside Keycloak, with hot reloading for a smoother development experience.
• Automated Theme Bundling: Keycloakify bundles your theme into a JAR file, ready to import directly into Keycloak.
• Version Compatibility: Themes generated with Keycloakify are backward compatible with Keycloak versions as far back as 11 and are .

• Built-In Real-Time Validation: Keycloakify includes real-time frontend validation by default. For example, users receive instant feedback, such as "The password must be at least 12 characters long," rather than waiting until they press the submit button.

• Community Support: We're here to help! If you're stuck or need guidance, reach out through our Discord channel or GitHub issues. We respond quickly and are happy to assist.

How does Keycloakify work?Understand how Keycloakify works under the hood

Pick Your Framework: React, Angular or Svelte

Keycloakify supports React, Angular, and Svelte, allowing you to work with the framework you're most familiar with. If you're only making CSS-level customizations to Keycloak's built-in theme, any of these frameworks will work. For a smoother experience, React is recommended, as it has the most complete integration.

For Angular and Svelte users, a few considerations apply:

• Account Themes: , requiring additional adjustments.

• Admin Themes: Only React supports custom Admin UIs. However, since the Admin UI is only seen by the Keycloak instance administrator, it is rarely customized.

• Angular Setup: . Themes must either be standalone projects or a subproject in a monorepo.

React provides the most seamless experience, but Angular and Svelte are fully supported for login and account themes with some extra effort, which covers the needs of most projects. Choose the framework that best suits your project and expertise. If you have any questions or concerns, feel free to ask us on our Discord channel.

Quick Start

Before futher reading, some practice!

React

git clone https://github.com/keycloakify/keycloakify-starter

Angular

git clone https://github.com/keycloakify/keycloakify-starter-angular-vite keycloakify-starter

Credit goes to @kathari00 for taking the initiative and driving the development of Angular support.

Svelte

git clone https://github.com/keycloakify/keycloakify-starter-svelte keycloakify-starter

Credit goes to @luca-peruzzo for taking the initiative and driving the development of Svelte support.

Let's create a story for the Login page and run .

cd keycloakify-starter

yarn install              # You can use any package manager (npm, pnpm, etc.)
                          # If you do, delete the .yarn.lock file to avoid conflicts.

npx keycloakify add-story # Select login.ftl (for example).
                          # Always use `npx` to run CLI tools installed in your project.
                          # This is standard practice across all modern JS projects,
                          # do not try to adapt this command based on your package 
                          # manager.

npm run storybook         # `npm run <script>`, `yarn <script>`, and `pnpm run <script>`
                          # are strictly equivalent. We use `npm run` here for 
                          # consistency and because `npm` is always available.

You should now be able to see the login pages in different scenarios:

Now, let's apply our first CSS customization.

Create the following stylesheet:

src/login/main.css

.kcFormHeaderClass {
    border: 3px solid red;
}

And import it:

React

src/login/KcPage.tsx

import "./main.css";
// ...

Angular

src/login/KcPage.ts

import "./main.css";
import { getDefaultPageComponent, type KcPage } from '@keycloakify/angular/login';
// ...

Svelte

src/login/KcPage.svelte

<script lang="ts">
  import "./main.css";
  import Template from '@keycloakify/svelte/login/Template.svelte';
  ...

This is what you should be getting:
