flowbite

A component library built on top of Tailwind CSS. If you're already using Tailwind and don't want to design every button, modal, dropdown, and navbar from scratch, Flowbite gives you pre-built components you can copy-paste into your project.

The free version includes 56 component categories: navbars, cards, modals, forms, tables, alerts, and more. All built with Tailwind utility classes, so they match whatever custom Tailwind theme you've set up. Framework support covers React, Vue, Svelte, and vanilla HTML.

Flowbite Pro ($149 one-time for personal, $299 for teams) adds 450+ advanced components, application UI blocks (dashboards, e-commerce layouts, admin panels), and Figma design files. That's where the real value is if you're building a full app.

The catch: the free components are solid but basic. Once you need a data table with sorting, a complex dashboard layout, or an e-commerce checkout flow, you're either building it yourself or paying for Pro. Also, you're locked into Tailwind. If you ever move away from it, these components don't come with you. For a free alternative, consider shadcn/ui (React only) which gives you owned, customizable components rather than a library dependency.
