Base44 entities

Entities are JSON-schema objects stored as

base44/entities/<Name>.jsonc

; writing the file is what defines the data model. The platform applies each entity's

rls

rules on every app-user request.

Pick the reference for this app

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.

For every app
