Base44 server-side code: backend functions (HTTP handlers in base44/functions/<name>/entry.ts on Cloudflare Workers) for Vite SPA apps, or TanStack Start server functions and server routes. Secrets, the Base44 SDK on the server, auth and service role, webhooks, admin-only handlers, frontend invocation, testing, and the InvokeLLM model table.

Base44 backend functions

A Vite SPA app runs server code as backend functions; a TanStack Start app runs it as server functions and server routes inside its own project. Writing the file deploys it.

Requires the Builder plan or above. The workspace's entitlement is reported by the agent-profile endpoint; on a lower plan the platform rejects the deploy.

Determine the app profile first. Call

GET /api/apps/{app_id}/agent-profile

(over the Base44 MCP

execute_api

tool, or with your Base44 CLI token); it returns the framework, app type, runtime, entitlements and the exact reference files to read. Without it, detect from the project files:

src/routes/__root.*

and

src/routeTree.gen.ts

mean TanStack Start;

app/_layout.*

means a native mobile (Expo) app; otherwise it is a Vite SPA.
