Pros
- +OpenTelemetry 原生支持，厂商中立，可与现有可观测性工具无缝集成
- +一行代码集成，提供从 LLM 到 GPU 的全栈监控能力
- +功能丰富的一体化平台，包含监控、评估、提示词管理、实验场地等完整工具链
- +Built on OpenTelemetry standard with official semantic conventions integration, ensuring compatibility with existing observability infrastructure
- +Open-source with strong community support (6,900+ GitHub stars) and active development backed by Y Combinator
- +Multi-language support covering both Python and JavaScript/TypeScript ecosystems for broad developer adoption
Cons
- -作为综合性平台，对于简单用例可能过于复杂
- -开源项目需要自行部署和维护基础设施
- -Requires familiarity with OpenTelemetry concepts and infrastructure setup, which may have a learning curve for teams new to observability
- -As a specialized tool for LLM observability, it may be overkill for simple AI applications or proof-of-concepts
