The Best Shadcn Extension Libraries

Nov 19, 2025UI Components3min read

shadcn/ui has become the go to choice for a lot of the new wave of vibe coders and product engineers who want beautiful components, clean design, and full control over their code. But what a lot of people do not know is that there is an entire ecosystem of incredible component libraries built on top of it.

These libraries take the shadcn/ui philosophy and expand it with new components, better aesthetics, and more prebuilt interfaces. If you already use it and want to elevate your design game, you are going to love these resources.

Below are five of my favorite extension libraries. Each one is open source, beautifully crafted, and especially perfect for anyone building with Next.js


1. Kibo UI

Kibo UI is one of the cleanest and most polished Shadcn-based libraries out right now and my current favorite one. It adds a ton of new more complex components including cards, charts, layouts, and more. Everything feels consistent and extremely well designed.


2. Tailark

Tailark focuses on giving developers complete sections, templates, and higher-level UI blocks. It is perfect if you want to build SaaS dashboards, marketing pages, or admin tools much faster without writing every component from scratch.


3. ReUI

ReUI takes the Shadcn UI style and makes it more expressive with bold visual patterns, interactive elements, and a wide variety of components not found in the base library. The design language feels modern, clean, and slightly more opinionated.


4. Blocks.so

Blocks is all about giving you prebuilt, production-ready section blocks so you can assemble pages visually. Think hero sections, pricing, feature lists, FAQ layouts, and more. If you are building websites, this one is a huge time-saver.


5. ElevenLabs UI

This one is newer, but it is incredibly impressive. ElevenLabs released their entire UI system as an open source Shadcn extension. It includes highly polished components with a strong product feel and very clean motion design.


Final Thoughts

These extension libraries give you more complex components and design patterns without forcing you into a rigid system. You still own every line of code.

I love open source, and I love seeing the community build things like this. Hopefully these help you level up your next project.
