PowerTraces

Trace & span ID generator

Generate valid random trace and span IDs, as plain hex, traceparent headers or B3.

How it works

A trace ID is 16 random bytes and a span ID is 8, written as lowercase hex. Neither may be all zeros.

Questions

Are these random enough?

They come from the browser’s cryptographic random generator.

When would I need these?

For tests, fixtures and replaying a request with a known trace ID.
