Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

A self-hosted observability middleware for FastAPI that detects API degradation using adaptive thresholds and provides actionable recovery suggestions. It's interesting because it focuses on reducing MTTR with a 'detect → evaluate → suggest → authorize → log' pipeline, includes incident replay capabilities, and was built for financial systems where latency directly impacts revenue.

Target audience: backend devs, devops, founders
