Flowbite — Open-Source UI Components Built with Tailwind CSS

Introduction

Flowbite provides a collection of pre-built UI components that use Tailwind CSS utility classes for styling and a lightweight JavaScript layer for interactivity. Instead of writing modal, dropdown, or tooltip logic from scratch, you drop in Flowbite components and get accessible, styled elements that match your Tailwind theme.

What Flowbite Does

• Ships 50+ interactive components: modals, dropdowns, navbars, tooltips, datepickers, and more
• Uses Tailwind CSS classes for styling so components match your design system
• Provides a small vanilla JS runtime for toggle, dismiss, and dropdown behaviors
• Offers framework-specific packages for React, Svelte, and Vue
• Includes Figma design files that mirror the code components

Architecture Overview

Flowbite components are HTML markup styled with Tailwind utility classes. Interactive behavior is handled by data attributes (like data-modal-toggle) that a JavaScript initialization script binds to event listeners. The JS layer uses Popper.js for positioning dropdowns and tooltips. Framework-specific packages wrap each component in idiomatic React/Svelte/Vue components with props-based configuration.

Self-Hosting & Configuration

• Install the npm package and add the Flowbite plugin to your Tailwind config
• Include the Flowbite JS file or import it in your entry point for data-attribute initialization
• For React, install flowbite-react and import components directly as JSX
• Customize colors and spacing by extending your Tailwind theme — Flowbite inherits those values
• Use the Tailwind content path config to include Flowbite's JS files for class purging

Key Features

• 50+ UI components covering common web application patterns
• Dark mode support via Tailwind's dark variant
• Full accessibility with ARIA attributes and keyboard navigation
• Framework bindings for React, Svelte, and Vue
• TypeScript support in framework-specific packages

FAQ

Q: Does Flowbite require Tailwind CSS? A: Yes. All components are styled with Tailwind utility classes and expect a configured Tailwind project.

Q: Can I use it without a JavaScript framework? A: Yes. The vanilla JS package works with plain HTML via data attributes for interactivity.

Q: Is Flowbite free? A: The core library is MIT-licensed. Flowbite Pro offers additional premium templates and blocks as a paid product.

Q: Does it work with Next.js? A: Yes. The flowbite-react package works with Next.js App Router and Server Components by marking interactive components as client-side.
