Microsoft Developer (Build) · Jun 04, 2026 · Product Launches

Rayfin is a code-first SDK and CLI for quickly building agentic apps deployed to Microsoft Fabric.

“with Rayfin, you have a code first SDK that makes it a lot more easier for you to figure out or define your data models, your roles, your permissions on the data itself”

Microsoft showcased Rayfin, a code-first SDK and CLI that lets developers define data models, roles, and permissions to build and deploy agentic applications to Microsoft Fabric with enterprise-grade security and governance.
