Retrace brings interactive debugging to AI agents

Retrace is a debugging and observability platform for AI agents that lets developers record, replay, and share execution traces. By tracking LLM calls, tool-use, and errors as spans, it allows developers to fork executions at failure points to test prompt or model fixes in real time.

// ANALYSIS

Retrace addresses the inherent non-determinism of AI agents by bringing classic interactive debugger concepts like time-traveling and forking to LLM workflows.

* Forking executions allows developers to test fixes on exact past failure states without re-running the entire sequence from scratch.

* First-divergence diffs help developers quickly distinguish between non-deterministic model variation and actual logic regressions.

* The focus on interactive debugging separates it from passive observability tools like Langfuse or Helicone by offering a playground to iterate on fixes.

* The free tier makes it highly accessible for developers starting to scale their agent workloads.
