Best For
Full-stack observability at scale — infrastructure, APM, logs, and LLM tracing in one platform
Infrastructure dashboards and alerting — best paired with Prometheus/Loki/Tempo for a fully open-source observability stack
Limitations
Expensive at scale; LLM observability is newer and less mature than dedicated tools like Langfuse; vendor lock-in on proprietary data format
No native LLM tracing; requires additional tooling (Langfuse, OpenTelemetry) for AI-specific observability; steep learning curve for the full LGTM stack
