    Use Your Own Data

    Humanlog makes it easy to load your own data in multiple ways:

    1. Direct from stdin

    $ cat app.log | humanlog

    2. Pull down logs for a quick debug session

    Stream logs from hosted services for quick debugging of production data. Since all data stays on your machine, you can safely use it at work without data sovereignty concerns:

    $ kubectl logs -l app=apisvc -f | humanlog

    3. Debug tracing integration locally with OpenTelemetry

    Instantly verify your tracing instrumentation works locally before pushing to production. See and debug your spans, trace context, and relationships immediately without deploying or waiting for production validation:

    $ export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317
