Logfire - Uncomplicated Observability
summary
Logfire is an observability platform with an open source Python SDK and a commercial hosted service that starts sending telemetry with one line of code (or two). It auto‑instruments FastAPI, httpx and psycopg, provides distributed traces, shows database queries and EXPLAIN plans, and captures recursive function calls via auto tracing without editing application code. Search and analytics use Postgres‑flavored SQL (demo query count jumps from 88 to 90 as live data arrives). Backfill writes compressed protobuf to disk when the network fails.
