Implementing Fabric Apps by Rayfin SDK

Hi pmscorca   ,
Thanks for reaching out to the Microsoft Fabric Community forum. 

Rayfin is intended to be the foundation for building data-driven applications directly on Microsoft Fabric, rather than just dashboards or reports. Fabric Apps combines data models, generated APIs, authentication, and hosting into a single development workflow, allowing developers to define their application backend in code and deploy it directly to Fabric.

For organizations looking to build resellable Fabric solutions, Rayfin appears to address a gap that traditionally existed between analytics and application development. Instead of delivering only semantic models, reports, and dashboards, solution providers could potentially package complete applications with:

• A managed backend
• Authentication and authorization
• APIs
• Operational and analytical data
• Power BI/Fabric reporting experiences

all running within the Fabric ecosystem.

The long-term goal seems to be enabling developers (and AI coding agents) to move from a data model to a production-ready application more quickly, while inheriting Fabric's governance, security, and scalability. In that sense, Rayfin could become a key enabler for creating reusable and distributable Fabric-based business applications rather than delivering data assets alone.

Regarding availability, Fabric Apps and the Rayfin-based development experience are currently in preview, so capabilities and timelines may evolve before general availability. The latest Microsoft documentation and announcements have not yet published a firm GA date.
