Zero-touch instrumentation — One call wraps every function and method in your codebase. No @decorator on each function, no manual setup per module.
Live call tree — See the full call hierarchy in your terminal as it happens, with color-coded timing (green/yellow/red) and [SLOW] tags on bottlenecks. Unlike cProfile or py-spy, there's no post-mortem step.
OpenTelemetry bridge — Flip one flag to export spans to Jaeger, Datadog, or any OTel-compatible backend. Cherry-pick which functions get spans.
Production-safe — Never masks exceptions, never wraps dunders or properties, skips already-wrapped functions. Designed to be safe even if accidentally left on.
