Shadcn alternatives
The main shadcn/ui alternatives and add-on libraries, what each is best for, what it costs, and where Caliper UI fits. Checked November 2026.
The short answer
Most of these libraries build on shadcn/ui rather than replace it, so start from what you are missing. For primitives you restyle yourself, stay on shadcn/ui. For more application components, add ReUI or Kibo UI. For dashboards and charts, use Tremor. For landing pages, use shadcnblocks, Magic UI or Tailark. For finished product screens with their states already designed, use Caliper UI. If you want an npm package instead of source in your repo, look at MUI, Mantine, Chakra UI or HeroUI.
The libraries compared
Prices and counts come from each library's own site in November 2026 and may have changed. Caliper UI is ours, so weigh that row accordingly.
| Library | Best for | Cost | Built on |
|---|---|---|---|
| shadcn/ui | The foundation: primitives you copy and restyle | Free, open source | Radix or Base UI |
| Caliper UI | Finished product UI: 116 free parts, 43 Pro screens, 8 templates | Free tier, Pro $199 once | Radix, plain React and CSS |
| ReUI | A large free set of application components | Free tier, paid All-Access | shadcn/ui |
| Kibo UI | Advanced composable parts such as tables and dropzones | Open source | shadcn/ui, Radix |
| Tremor | Dashboards and charts, 35+ components | Open source | Tailwind CSS, Radix |
| coss ui | A modern general-purpose component set | Open source | Base UI |
| shadcnblocks | Marketing and app blocks at volume | Free tier, paid from $149 once | shadcn/ui |
| shadcn Studio | 1,000+ component variants and templates | Free tier, paid from $99 once (sale price) | Base UI or Radix |
| shadcn.io | A very large block catalogue across React, Vue, Svelte and Solid | 175 free components, paid Pro | Base UI, Radix, Ark UI, React Aria |
| Magic UI | Animated components for landing pages, 150+ free | Free tier, Pro $199 once | shadcn/ui conventions |
| Animate UI | Animated versions of familiar primitives | See their site | Radix, Base UI, React Aria |
| Tailark | Marketing site blocks | Free tier, paid from $249 once | shadcn/ui |
How to choose
Source or package. Copied source is yours to change, and yours to keep updated. A package updates with one bump and limits how far you can change it.
The primitive layer. Radix and Base UI have different APIs. Mixing libraries built on each leaves you with two sets of conventions, so check before you combine them.
Finished states, not counts. A thousand variants and a hundred parts are not comparable by number. Open a part and look for its loading, empty and error states, then try it with the keyboard.
One source of truth. Pick one library for buttons, inputs and dialogs, and add others only for what it lacks.
Where Caliper UI fits
Caliper UI is for teams building product UI who would rather not design every state. It has 116 free parts under MIT and 602 Pro parts and blocks, drawn to one specification. Pro is one payment of $199 for one developer, with a year of updates. An MCP server lets Claude Code and Cursor search and install parts.
It is the wrong pick if you need a large community, want Vue or Svelte, or mostly build marketing sites: it is newer, React only, and has fewer marketing blocks than shadcnblocks.
Questions
What is the best alternative to shadcn/ui?
It depends on the gap. Most teams keep shadcn/ui as the base and add a library for what it lacks. For an npm package instead of copied source, MUI and Mantine are the usual choices.
Do these libraries work with shadcn/ui?
Most install with the shadcn CLI and follow its conventions. Check whether a library targets Radix or Base UI before mixing it into an existing project.
What is the difference between a component library and a shadcn registry?
A component library is usually a package you import. A registry serves source files that the shadcn CLI copies into your repo, so you own and edit them.
Which shadcn libraries have a one-time price?
shadcnblocks, shadcn Studio, Magic UI Pro, Tailark and Caliper UI Pro all sell one-time licences. Plans differ in seats and updates, so compare those too.
