Runtime-verified Verified from authenticated runtime evidence.
OpenTelemetry-native observability platform built by the Pydantic team. One-line instrumentation for FastAPI, SQLAlchemy, httpx, requests, Anthropic, OpenAI, and 20+ Python libraries via logfire.instrument_*() helpers. Spans carry structured attributes queryable in the Logfire UI. OTLP export to any OpenTelemetry backend. Confidence is docs-derived.
Python SDK: logfire.configure() for initialization; logfire.span(), logfire.info/warn/error() for manual instrumentation; logfire.instrument_fastapi(), logfire.instrument_sqlalchemy(), logfire.instrument_openai(), etc. for auto-instrumentation; OTLP HTTP/gRPC exporter for external backends; REST API for programmatic trace query via Logfire SQL UI.
Write token per project (generated in Logfire console) sent as Bearer token on OTLP Authorization header; read tokens for dashboard access; project-level access control; scrubbing rules remove PII from span attributes before export to Logfire cloud; self-hosted OTLP export requires no token to your own collector.
Auto-instrumentation wraps framework internals and emits spans without blocking; structured attributes enable fast querying vs unstructured log strings; scrubbing runs before data leaves the process; OTLP export is async non-blocking; SDK is designed to be a zero-overhead pass-through when Logfire cloud is unavailable; rate limits not documented for SDK path.
Documentation covers quickstart with logfire.configure(), per-library instrument guides, OTLP exporter setup, SQL query interface tutorial, and PII scrubbing configuration. Pydantic team authorship means tight integration with Pydantic v2 models as log data. Active Discord community. Confidence is docs-derived.
