Final Thoughts

All of these libraries are free, actively maintained, and beginner-friendly, which makes them great starting points no matter your experience level. Since each has its own design philosophy and component set, it’s worth experimenting with a few to see which one feels most natural for your workflow. For example, I often combine Tailwind CSS with Flowbite or DaisyUI when working on small projects, since they’re lightweight and make it easy to prototype quickly without much setup. On the other hand, when building larger React applications that require more robust component ecosystems, I usually turn to Material-UI (MUI) or Ant Design because they provide a wide range of ready-to-use components, consistent design systems, and strong community support.
