A good fit is LangSmith.
It supports:
- Privacy-safe logging: you can control what gets recorded/redacted in traces
- Sampling controls: useful for monitoring production traffic without logging everything
- Production prompt testing/monitoring: traces, evaluations, and debugging for LLM apps
If you want, I can also compare LangSmith with Langfuse, PromptLayer, and OpenAI Evals for privacy and production monitoring features.
