Build an enterprise app in minutes with Rayfin, an agent-friendly, code-first backend-as-a-service. In this demo, we show how an AI agent generates a full stack web app with a managed database, authentication, and backend services. Learn how to connect the app to existing data in your Microsoft Fabric data estate, define services in code, and use Fabric’s built-in analytics, BI, and AI capabilities to power insights and intelligent experiences.
Big announcement from Microsoft Build 2026: Rayfin is now part of Microsoft Fabric.
This is an exciting step for the Fabric ecosystem, extending its capabilities beyond analytics and data management into application backend development.
What makes Rayfin interesting?
🔹 Build – Create data models, APIs, and business logic using a developer-first approach.
🔹 Deploy – Publish applications directly within Fabric with a streamlined deployment process.
🔹 Govern – Benefit from built-in security, compliance, and enterprise governance.
One of the biggest advantages is how Rayfin brings application development and data closer together:
✅ Native connectivity with OneLake
✅ AI and analytics built into the foundation
✅ A unified environment for data, applications, and AI workloads
✅ Open-source SDK and CLI for modern development practices
This could change how organizations approach intelligent application development. Instead of managing multiple disconnected services, teams can build and scale applications directly where their data resides, while maintaining governance and security.
For developers, architects, and business leaders, Rayfin represents another step toward a more integrated and AI-ready technology stack.
Looking forward to seeing the innovative solutions the community builds with it.
