NorthStar

An observability, debugging, and evaluation platform for AI agents that records traces, child spans, events, metrics, and errors without changing application control flow. The Python SDK ships with automatic LLM instrumentation for OpenAI and Anthropic, a context-managed tracing API (`trace`/`span`/`observe`), PII redaction, and a daemon-thread background worker that batches records to a Supabase Edge Function. The backend uses a private Postgres schema with row-level security, SHA-256-hashed API keys, and idempotent ingestion. A separate Next.js dashboard visualizes sessions, runs, and spans for debugging and rubric-based evaluation.
