How Zip Uses LangSmith and LangGraph to Ship New Features Faster

This post details how Zip's procurement platform leveraged LangGraph and LangSmith to significantly accelerate their AI feature development. Previously, their in-house LLM orchestration and tracing pipeline was slow and lacked necessary detail, taking weeks to add new features. By adopting LangGraph and LangSmith, Zip gained automatic, detailed tracing of node interactions and LLM calls without custom code. This led to faster iteration cycles, adoption by other teams, and the establishment of an evaluation setup to prevent regressions. The post highlights the benefits of using these tools over building custom solutions, emphasizing improved developer velocity and system robustness.
