stacks
Eval, tracing, and prompt management from the LangChain team.
End-to-end platform: trace runs, build datasets, run experiments, manage prompts. Tightly integrated with LangChain and LangGraph but usable independently.
Strengths
- End-to-end coverage (trace, eval, prompt)
- Native LangChain/LangGraph integration
Tradeoffs
- Most natural for LangChain-stack teams
