Fitz simplifies FastAPI observability with two decorators vs OpenTelemetry's 60 lines
Fitz, a new Python library, claims to reduce FastAPI observability setup to two decorators and an env var, compared to OpenTelemetry's six packages and 60 lines of config. It auto-correlates trace IDs between logs and spans, and redacts secrets in logs. The library targets developers who want production-ready monitoring without manual glue code.
