How we turned thousands of spans into a view a product manager can understand in ten seconds.

Traces are for everyone

Engineers love flame graphs. Everyone else needs a story: what came in, what the box decided, what came out and why. We rebuilt the trace view around that narrative.

Each hop is summarised in plain language, with the raw data one click away.

Small details, big difference

Cost and latency are shown inline next to every step, and anything unusual is highlighted automatically — so the interesting part of a trace finds you.
