Score: 6.8/10 (Innovation: 7, Technical: 7, Documentation: 6, Utility: 7)

Retrace is an open-source SDK and dashboard that records every LLM call, tool invocation, and error from AI agents, enabling replay, forking from failure points, and proving fixes via re-execution. Its innovative combination of deterministic replay for agent workflows with a CI/CD gate metaphor addresses a real debugging gap for AI engineering teams.

Target audience: backend devs, ai engineers, devops
