Questions, answered

Who maintains OpenLLMetry?

It is maintained by Traceloop at traceloop/openllmetry, with 1,134 forks.

Is OpenLLMetry free to use?

Yes. It is released under the Apache-2.0 license, which permits commercial use, modification, and redistribution. Read the LICENSE file for the exact terms.

Do I need a paid API to use it?

The instrumentation is free; you bring your own tracing backend, self-hosted or otherwise.

How does it compare to LangSmith or Langfuse?

It is OpenTelemetry-native and vendor-neutral, so it fits existing observability stacks rather than a dedicated LLM platform.

How do I get started?

Install the package, initialize it in your app per the docs, and point it at your collector.
