The short version

  • Each has a real cost: shadcn/ui no upgrade path: once copied, upstream fixes and improvements are yours to port by hand; Zipkin less active development and smaller community momentum than Jaeger
  • They diverge on capability: shadcn/ui covers Copy, not install, Zipkin covers Trace collection and search.
  • Prices and features above were last checked on 29 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

shadcn/ui

  • Projects already using Tailwind that need accessible components without a theming fightnot Zipkin
  • Design systems that will diverge from any library’s defaults anywaynot Zipkin
  • Teams who have been burned by breaking changes in component library upgradesnot Zipkin

Zipkin

  • Adding distributed tracing quickly without standing up heavy infrastructurenot shadcn/ui
  • Java and Spring Boot estates, where instrumentation support is long-establishednot shadcn/ui
  • Small deployments where Jaeger is more than the problem requiresnot shadcn/ui

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

shadcn/ui

  • No upgrade path: once copied, upstream fixes and improvements are yours to port by hand
  • Requires Tailwind and React, so it is not an option outside that stack
  • Component code lives in your repository, which grows it and puts maintenance on your team
  • Its popularity has made the default look recognisable, which undercuts the customisation argument

Zipkin

  • Less active development and smaller community momentum than Jaeger
  • Fewer features: sampling, storage options and UI are all more limited
  • The interface is dated and slower to work with on large trace volumes
  • Tracing alone still leaves metrics and logs in separate tools during an incident

Answered from the vendors’ own pages

shadcn/ui: Is shadcn/ui free?

Yes, open source and free for commercial use.

Zipkin: Is Zipkin free?

Yes, open source with no licence fee.

shadcn/ui: Why is it not an npm package?

So you own the code. Components are copied into your project, which makes customisation trivial — at the cost of receiving no automatic updates.

Zipkin: Zipkin or Jaeger?

Jaeger has more momentum, more features and CNCF backing. Zipkin is lighter and quicker to stand up, and remains well supported in the Java and Spring ecosystem.

shadcn/ui: Do I need Tailwind?

Yes. Components are styled with Tailwind utility classes and built on Radix primitives, so both are required.

Zipkin: Does Zipkin work with OpenTelemetry?

Yes. OpenTelemetry can export to Zipkin, which is now the usual way to instrument for it.
