Observability & evaluation

Pydantic Logfire

Python-focused instrumentation and rich data exploration built on standard OpenTelemetry signals.

Overview

Research summary

Pydantic Logfire combines developer-friendly instrumentation with an observability platform for applications and AI systems. Its Python SDK wraps OpenTelemetry, integrates with common frameworks and Pydantic, and can send telemetry to compatible backends. The Logfire service adds a visual interface and SQL-based exploration of captured data, including workflows for LLM applications and agents. Licensing is split: the public SDK is MIT licensed, while the recording backend and user interface are closed source. Self-hosting that platform requires a separate enterprise license.
