SwarmTrace - Time-travel debugger for multi-agent AI pipelines
by•
Debugging multi-agent LLM systems is painful. When a pipeline fails, you don't know which agent caused it and have to re-run everything from scratch.
SwarmTrace fixes this:
- Span tree viz — every agent action as an OTel graph
- Time-travel replay — fork any step, edit prompt, replay downstream only
- LLM-as-judge — auto scoring of each agent's output
- WebSocket streaming, OTLP export, PyPI SDK
