shadcn/ui Review

Worth it

Should I use shadcn/ui?

Composable, accessible components with thoughtful defaults. Build your own component library with code you can customize, extend, and make your own. - ui.shadcn.com

· 1 month ago

Free and excellent if your team writes React and Tailwind and wants to own its UI code outright. Skip it if you're not on React or can't maintain copied-in components yourselves.

Confidence

Medium. Based on ~50 public sources; mostly developer-community discussion since the product is free open source rather than a paid purchase.

Gotchas - check before you buy

high

Third-party registry components are a real attack surface: Plate editor shipped XSS CVEs apps inherited.

high

Researchers showed registry injection could run arbitrary shell commands during component install; vet registries.

medium

You maintain copied code forever; switching libraries later means rewrites across your app.

low

Paid ecosystem: Figma kits, pro blocks, and templates cost extra from third-party sellers.

Pros and cons

Pros

  • Completely free and open source
  • You copy the code, so you own and customize everything
  • Accessible components with thoughtful defaults
  • Built on Radix primitives, a battle-tested behavior layer
  • Large ecosystem of blocks, templates, and Figma kits

Cons

  • Code is copied in, so upstream fixes and updates aren't automatic
  • Requires React and Tailwind skills; beginners told to learn those first
  • Maintenance and customization overhead divides user opinion
  • No official security page found on the docs site

Sources & method

- 10 sources - Open source with no vendor security page found; real CVEs exist in ecosystem registry components plus documented registry-injection risk.
