"Another thing often missed by other frameworks are dedicated devtools"

From my experience, PydanticAI really nailed it with Logfire—debugging[0] agents was significantly easier and more effective compared to the other frameworks and libraries I tested.

Logfire is a tracing app, an equivalent of Jaeger and other Otel UIs. While I wont discuss reimplementation-vs-integration in this case, traces are just one way of debugging. am-dbg focuses on debugging of the state consensus, instead of the execution tree, without requiring a SaaS account.

Execution trees are enough for workflows, but bots/agents aren't simple workflows.
