Best for Product teams that need non-engineers to collaborate directly on prompts and evaluation, not just engineers viewing traces. Teams that want evaluation and experimentation as the primary workflow, with production monitoring layered on top. Teams already building on LangChain/LangGraph that want tracing and evaluation from the same vendor. Teams that want prompts version-controlled and tested outside of application code, with logging tied to each version.
