Data, apps, and agents: the future of app dev with Rayfin | BRK225
Microsoft introduces Rayfin, a code-defined backend SDK/CLI that deploys to Microsoft Fabric for the agentic coding era.
“Rayfen is the back-end for this new AI coding era.”
At Microsoft Build (BRK225), Microsoft unveiled Rayfin, an SDK and CLI that lets a human or an AI agent define an entire backend—database, functions, storage, and access policies—in code and deploy it to Microsoft Fabric with one command. It targets the gap between casual 'vibe coding' and enterprise apps that need real authentication, compliance, and governance, signaling Microsoft's bid to own the backend layer for AI-generated applications.
