The backend your AI-built app already has

User Accounts

Real auth for your app's end users

Give your generated app real user accounts — registration, login, sessions, and password reset — without wiring Firebase or Supabase Auth. End-user accounts are separate from your MonstarX builder login. Sessions are handled by the platform; your app receives tokens and user profiles through the mx.auth SDK.

const session = await mx.auth.login({
  email: '[email protected]',
  password: '••••••••',
});

// Current user anywhere in the app
const me = await mx.auth.me();

File Storage

Uploads and public URLs without a bucket

Store files for your app — uploads, avatars, documents, and media — with per-project isolation. The platform handles storage infrastructure; your app gets upload endpoints and public file URLs through mx.storage.

const { url, path } = await mx.storage.upload({
  file: selectedFile,
  folder: 'avatars',
});

Email

Transactional email from your app's name

Send transactional email — welcome messages, password resets, order confirmations, notifications — from your generated app without a Resend or SendGrid account. Recipients do not need a MonstarX account; volume is limited, not identity-limited.

Replaces optional BYO: Resend

await mx.email.send({
  to: user.email,
  subject: 'Your booking is confirmed',
  html: '<p>See you on Tuesday at 2pm.</p>',
});

Maps & Geocoding

Addresses to coordinates, maps without keys

Geocode addresses to coordinates and reverse-geocode coordinates to places through mx.map. Basemaps in generated apps use Leaflet and OpenStreetMap — no map API key required. For 3D terrain and custom cartography, connect Mapbox as a BYO connector.

Replaces optional BYO: Google Maps (geocoding)

const { lat, lng } = await mx.map.geocode({
  address: '9 Straits View, Singapore',
});

Edge Functions

Scheduled jobs, webhooks, and table hooks

Declare server-side behavior the platform runs for you — scheduled cron jobs, inbound webhook endpoints for Stripe and form services, and table hooks that fire when rows change. Functions are declared in a structured config file from a closed action vocabulary; the platform executes them at the edge.

// .monstarx/functions.json
{
  "hooks": [{
    "table": "orders",
    "on": "insert",
    "action": "email:notify-admin"
  }]
}

Country Data

Live government & civic datasets — Asia-Pacific first

Access live country-specific datasets — weather, transit, air quality, company registry, carpark availability, and more — through MCP servers proxied by MXCloud. MonstarX is Singapore-based; our deepest coverage spans Southeast and South Asia, with dedicated servers per market.

const weather = await mx.mcp.call('sg', 'sg_weather_2h', {});
