A modern Backend-as-a-Service (BaaS) platform built for the agentic era.
Define your data model with TypeScript decorators — Rayfin provisions and manages the backend for you.
npm create @microsoft/rayfin@latestThis CLI scaffolds a new Rayfin project with everything you need: data models, authentication, APIs, and a ready-to-deploy app.
Rayfin is a fully managed Backend-as-a-Service (BaaS) platform that helps teams build and ship applications faster without building or operating backend infrastructure.
With Rayfin, you define your data model using TypeScript decorators, and the platform automatically provides and manages:
- Database
- Authentication
- Data APIs
- Storage
- Hosting
So you can focus on building your application, not backend services.
npm create @microsoft/rayfin@latest # scaffold a new project
npx rayfin up # deploy and runRayfin is built on Microsoft Fabric, which provides centralized data discovery, access control, and governance capabilities -- helping organizations manage data access, sharing, and compliance consistently across workloads.
This means your Rayfin apps inherit enterprise-grade security and governance out of the box, so you can build fast without compromising on compliance.
👉 Get started with Microsoft Fabric
Rayfin supports a pure local development experience — no cloud resources required. This is currently experimental and great for trying out Rayfin or building offline.
👉 See the Todo Local Experimental template to get started.
