# OpenTelemetry Support | Sentry for Fastify

The Sentry JavaScript SDK creates and sends spans without an OpenTelemetry pipeline. For the default setup, see [Tracing](https://docs.sentry.io/platforms/javascript/guides/fastify/tracing.md).

If your application also uses OpenTelemetry, choose a setup based on which SDK manages tracing:

* #### [Capture Spans from OpenTelemetry APIs](https://docs.sentry.io/platforms/javascript/guides/fastify/opentelemetry/using-opentelemetry-apis.md)

  Let Sentry capture and send spans created by OpenTelemetry APIs.

* #### [Use Your Own OpenTelemetry Pipeline](https://docs.sentry.io/platforms/javascript/guides/fastify/opentelemetry/custom-setup.md)

  Connect your existing OpenTelemetry pipeline to Sentry while keeping control of tracing.
