Question

What is a trace viewer for AI agents, and how do I view a trace?

Short answer

A trace viewer shows one run as a timeline of steps so you can open each model call, tool call and error in order. To view a trace in Tracify, open your project, pick a run from the run list, and read its spans from first to last.

In more detail

  • What you see

    Every span with its input, output, duration, tokens and cost, plus the status of each step.

  • How to open one

    Send a run with the SDK, open the project, choose the run in the list and click through its spans.

  • Looking for a Playwright trace?

    Tracify is for AI agent runs, not a viewer for Playwright trace.zip files. If a browser agent runs through Playwright, the Playwright guide shows how to send those test runs next to the agent's own steps.

Answers are the start.

Open a real trace and see it for yourself.
