Factory AI implemented self-hosted LangSmith to address observability challenges in their SDLC automation platform, particularly for their Code Droid system. By integrating LangSmith with AWS CloudWatch logs and utilizing its Feedback API, they achieved comprehensive LLM pipeline monitoring, automated feedback collection, and streamlined prompt optimization. This resulted in a 2x improvement in iteration speed, 20% reduction in open-to-merge time, and 3x reduction in code churn.
