Failure Analysis

The booking_agent failed during context handoff because the dates parameter was dropped from the state memory.

Built for production.

Stop hunting down console logs. Traceloop captures exactly what your agent was thinking, all in one place.

Local-First Storage

All trace logs stay on your machine by default. No data leaves your secure execution environment unless you want it to.

Full Execution Timelines

We record every HTTP request, tool interaction, token usage, and sub-agent context handoff automatically.

Enterprise Security

Our agent monitors LLM outputs for PII leaks and automatically sanitizes payloads before storage.

Team Collaboration (Cloud)

Sync your traces to a shared Traceloop Cloud workspace so your engineering team can debug agent failures together.
