Framework Specific Integrations With Automatic Instrumentation

via “automatic-instrumentation-via-ast-rewriting”

AI observability platform for production LLM and agent systems.

Unique: Uses Python AST rewriting at import time to inject span creation code into function bodies without requiring decorators or manual instrumentation; plugin architecture enables framework-specific handlers (e.g., FastAPI middleware, SQLAlchemy event listeners) to be registered and applied automatically during AST transformation

vs others: More comprehensive than decorator-based instrumentation (covers entire codebase automatically) and less invasive than monkey-patching (uses standard Python import hooks); more flexible than OpenTelemetry's auto-instrumentation packages because it supports custom instrumentation rules and Pydantic-specific features
