Build like a startup. Deploy like an enterprise.

Define your backend in TypeScript: database, type-safe APIs, Entra ID auth, functions, storage, and hosting. Rayfin deploys it to Microsoft Fabric — inside your organization’s boundary.

Start with an agent

Set up a new Rayfin app for me, end to end.

Rayfin is a backend platform for TypeScript developers on Microsoft Fabric. Before writing any code, read https://rayfin.ai/llms.txt and https://rayfin.ai/docs/reference/agent-rules.md — every page on that site is available as raw Markdown by appending .md to its URL.

Then do the work yourself rather than printing steps for me:
1. Scaffold a project with `npm create @microsoft/rayfin@latest my-app` and install dependencies.
2. Sign in with `npx rayfin login`.
3. Deploy the backend with `npx rayfin up` and confirm it with `npx rayfin up status`.
4. Start the frontend with `npm run dev` and tell me the URL to open.

Then explain what the starter app does and where the data model lives.

Hand it to a coding agent with a terminal — it scaffolds the project, deploys the backend, and explains what it built.
