The short version

  • Each has a real cost: Jaeger tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps; Radix UI you write all the styling, so time to a finished interface is much longer than with a styled library
  • They diverge on capability: Jaeger covers Distributed trace search, Radix UI covers Unstyled primitives.
  • Prices and features above were last checked on 29 August 2026.

  • Controlled or uncontrolled

What people use each for

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

Jaeger

  • Finding which service in a request path causes the latencynot Radix UI
  • Understanding real service dependencies rather than the diagram on the wikinot Radix UI
  • Debugging failures that only appear under production traffic patternsnot Radix UI

Radix UI

  • Design systems that need correct accessibility without inherited visual opinionsnot Jaeger
  • Replacing hand-built dropdowns and dialogs that have accessibility bugsnot Jaeger
  • Teams with a designer whose output should not be constrained by a library’s themenot Jaeger

Where each one falls short

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

Jaeger

  • Tracing is only as good as the instrumentation, and partial instrumentation produces misleading gaps
  • Storage is the real operational cost: high-volume tracing on Elasticsearch or Cassandra is a cluster to run and pay for
  • Traces alone, without correlated metrics and logs, leave you switching between tools during an incident

Radix UI

  • You write all the styling, so time to a finished interface is much longer than with a styled library
  • Composable part-based APIs are more verbose than a single component with props
  • Covers primitives rather than complex widgets, so data grids and date pickers come from elsewhere

Jaeger runs on Linux, Kubernetes, Docker. Radix UI runs on Web.
Can I use Jaeger for free?
Both have a free tier, so you can try either at no cost before committing.
What is Jaeger best used for?
Jaeger is most often used for finding which service in a request path causes the latency, understanding real service dependencies rather than the diagram on the wiki, debugging failures that only appear under production traffic patterns. Of those, finding which service in a request path causes the latency and understanding real service dependencies rather than the diagram on the wiki are not what Radix UI is typically brought in for.
What can Jaeger do that Radix UI cannot?
Jaeger covers Distributed trace search, Dependency graph, Adaptive sampling, Pluggable storage. Radix UI covers Unstyled primitives, Accessibility built in, Composable API, Controlled or uncontrolled.

Answered from the vendors’ own pages

Jaeger: Is Jaeger free?

Yes, open source and CNCF-graduated. Costs are the storage backend you run.

Radix UI: Is Radix UI free?

Yes, open source under the MIT licence.

Jaeger: Do I use Jaeger or OpenTelemetry?

Both, usually. Instrument with OpenTelemetry and use Jaeger to store and query the traces.

Radix UI: Why use unstyled components?

Because accessibility is the hard part and visual design is the part teams want to own. Radix gives the first and stays out of the second.

Jaeger: Does Jaeger handle metrics and logs?

No. It is a tracing system. Metrics and logs need Prometheus, Loki or an equivalent.

Radix UI: What is the relationship with shadcn/ui?

shadcn/ui is built on Radix primitives, adding Tailwind styling and copy-paste distribution on top.
