About Retrace Expand
Retrace provides a specialized platform for AI developers and engineers to debug and test the complex behavior of AI agents. It records every LLM call and tool invocation, giving teams a detailed trace of agent execution.
This allows users to replay agent runs, identify points of failure, and 'fork' from specific errors to test fixes interactively. The platform also supports automated regression testing through CI integration, ensuring agent reliability as development progresses.
By focusing on execution replay and proactive debugging, Retrace offers a targeted product for maintaining the stability and predictability of AI agents in production environments.
