“Best” depends on what kind of agents you mean and what you need to monitor.
If you mean AI/LLM agents in production
Top choices are usually:
- LangSmith — best for teams already using LangChain/LangGraph; strong tracing, debugging, evals, and dataset-based testing.
- OpenTelemetry + a backend like Datadog / New Relic / Grafana — best if you want vendor flexibility and standard observability across your whole stack.
- Helicone — good for lightweight LLM request monitoring, cost tracking, and prompt/response logs.
- Arize Phoenix — strong for evaluation, tracing, and LLM debugging, especially if you care about quality analysis.
- Weights & Biases Weave — useful for experiment tracking plus tracing and evaluation workflows.
If you mean traditional software agents / distributed services
- Datadog is often the strongest all-around production monitoring platform.
- Grafana + Prometheus + Loki + Tempo is great if you want open-source and control.
- New Relic is also a solid full-stack APM option.
Practical recommendation
- Best all-around for production AI agents: LangSmith if you’re in the LangChain ecosystem.
- Best open standard approach: OpenTelemetry + Datadog/Grafana.
- Best for simple LLM usage monitoring: Helicone.
If you tell me:
- what kind of agents you’re running,
- your stack, and
- whether you care most about traces, evals, cost, or alerts,
I can recommend a more specific platform.
