By default, open telemmetry will try to send traces to a remote http endpoint, unless there is a local exporter in the code base to avoid that behaviour.

Otel has value for things crossing microservices in production, much less in local for a single app.

Often, languages running on dotnet or the JVM already enjoy great tooling for quite a few years, and so locally they are much better than otel.
