What Logfire AI Trace does
Logfire is an observability platform from Pydantic, built on OpenTelemetry, that traces a whole AI application rather than only its LLM calls. It is for teams building AI applications and agents who want model calls, tool calls, API requests and database queries in one trace. Named features include dedicated Agents and LLMs views with token usage and cost, RAG pipeline tracing, evals that attach scores to spans, a SQL query engine called FusionFire, an MCP server for coding agents, and SDKs for Python, JavaScript/TypeScript and Rust. Security options cover PII scrubbing, SSO and audit logs. Pricing is freemium: a free Personal plan, Team at $49 per month, Growth at $249 per month, and custom Enterprise.
