THE PROBLEM

Logs report each attempt as its own line, so a single run is scattered across three streams. Finding the call that went wrong means reading all of them.

HOW TRACEWELL HANDLES IT

Each run becomes one trace: a tree of spans drawn to scale. Parallel tool calls share a row, slow spans stand out, and every span carries tokens and cost.

01

How it works

Three steps from nothing to useful.

01

Wrap your agent

One function call turns each invocation into a run.

02

Open the trace

See the waterfall first, then the words inside any span.

03

Share a link

Send a redacted run to a teammate or a customer, no account needed.
