Best For
Full-stack observability at scale — infrastructure, APM, logs, and LLM tracing in one platform
Lightweight LLM proxy with cost tracking, caching, and rate limiting — minimal integration effort
Limitations
Expensive at scale; LLM observability is newer and less mature than dedicated tools like Langfuse; vendor lock-in on proprietary data format
Proxy-based architecture adds a network hop; less deep tracing than Langfuse; evaluation features are basic
