Logfire
OpenTelemetry-native observability platform from the Pydantic team, designed for Python AI applications and LLM agents. Provides structured logging, distributed traces, and dashboards with first-class support for Pydantic AI, FastAPI, and HTTPX. Simple SDK with one-line setup for agent call tracing.
Viable option — review the tradeoffs
You need end-to-end visibility into your Python AI agents and LLM apps to debug whether failures stem from model calls, tool interactions, or backend services.
Instant traces with live spans and structured logs; excels at multi-turn LLM flows but UI can lag on high-volume traces.
You're tired of vendor lock-in from siloed AI observability tools that ignore your full stack.
Portable traces across backends; AI features like cost tracking shine, though generic OTel apps need manual spans for best results.
Python-Centric AI Polish
SDKs are strongest for Python AI stacks (Pydantic, FastAPI); other languages get basic OTel support without AI-specific UI features.
Free Tier Data Retention
Traces expire after 14 days on free plan; high-volume agent testing fills quota fast — upgrade or sample aggressively to avoid cutoff.

What It Actually Does
Logfire tracks and visualizes logs, traces, and metrics from Python AI apps and agents in easy dashboards. It uses a simple one-line setup to monitor LLM calls, APIs, and databases without lock-in.
