A baker's-dozen of insight crammed into one ring.
Summary
Microsoft announced Rayfin, an open-source SDK and CLI at Build 2026, designed to bridge the gap between rapid "vibe coding" prototyping and enterprise production deployment. Rayfin lets developers and coding agents define application backends entirely in code—including data models, business logic, and access policies—and deploy them directly to Microsoft Fabric. The tool aims to deliver applications that are already secured, compliant, and integrated with enterprise data estates, addressing the governance and security challenges that typically prevent vibe-coded prototypes from reaching production.

The result, Microsoft says, is an application that arrives in production already secured, compliant, and integrated with the enterprise data estate.
Vibe coding has made it easier than ever to build applications. Getting those applications into enterprise production is still the hard part.
