MonstarX Cloud — the backend every app gets
In shortMonstarX Cloud is the backend built into every app you make — a database, sign-up and sign-in, email, file storage, AI, web search, maps and a safe place for keys. It is on from the first build and costs no setup. You see and manage it in the Backend tab, and you can switch off Email, AI, Web Search or Storage to use your own provider instead.
An app is more than its pages. It has to remember things, let people sign in, send emails and keep the photos people upload. That hidden part is called the backend. In MonstarX you do not build or rent a backend: every app gets one, called MonstarX Cloud, from its first build.
You describe what you want (“people can sign up and post recipes with a photo”), and MonstarX uses the right parts of MonstarX Cloud for you. There are no servers to set up, no accounts to open and no keys to paste.
What does every app get?
Section titled “What does every app get?”| Service | What it does for your app | Read more |
|---|---|---|
| Database | Keeps your app’s information — orders, bookings, posts, sign-ups — safely stored and shared between everyone who uses the app. | Your app’s database |
| Auth (user accounts) | Sign-up, sign-in, sign-out and password reset for the people who use your app. | User accounts |
Sends emails from your app’s own address, like brew-bean@monstarx.app — confirmations, receipts, welcome notes. | Email from your app | |
| Storage | Keeps files: photos people upload, PDFs, pictures your app makes. | File storage |
| AI | Lets your app write text, answer questions, make images, speak and listen. | AI in your app |
| Web Search | Lets your app look things up on the live web and cite its sources. | AI in your app |
| Maps | A world map of countries and a street map you can pan and zoom — no API key. | Maps in your app |
| Country data | Live public data — weather, transport, car parks, registries, holidays — for Singapore, Japan, Malaysia, India, Indonesia, the UAE and the Philippines. Enable a country in one click. | Use live country data |
| Secrets | A locked box for the keys of other services your app uses. | Secrets and API keys |
On top of these, your app’s data can be read and written from other software through a REST API, and connectors plug in outside services like Stripe or Twilio.
Where do I see my app’s backend?
Section titled “Where do I see my app’s backend?”Open your project and click Backend in the top bar. Everything about your app’s backend lives there, in sections along the top.
| Section | What you find there |
|---|---|
| Cloud | The MonstarX Cloud services with their on/off switches, where your app keeps its data, and the list of connectors. |
| Database | Every table with its number of rows, the migrations, and a box to run read-only SQL. |
| Users | Everyone who has signed up in your app, with Ban and delete. |
| Files | Every file your app has stored, with preview, download and delete. |
| Emails | Every email your app has sent, and how many it may still send this hour and today. |
| AI | Every AI call your app has made, and how much of today’s allowance is left. |
| Country data | The countries whose live public data your app may use, their tools, and your app’s latest calls. |
| Secrets | The keys and settings your app reads, stored encrypted. |
| Localization | Your app’s translations. This section only appears once your app has more than one language. |
On a phone, Backend is one of the views you switch between at the top of the workspace.
Can I switch a service off and use my own?
Section titled “Can I switch a service off and use my own?”Yes, for Email, AI, Web Search and Storage. Database and Auth are marked core: every app needs them, so they cannot be switched off.
-
Connect your own provider under Connectors — for example Resend for email or OpenAI for AI — and ask MonstarX to use it. See Connectors.
-
Open BackendCloud and click the switch on the service you want to turn off.
-
Confirm. MonstarX asks first, because the app then needs its own provider for that job.
A service you switch off disappears from your app straight away: its code can no longer reach it, and MonstarX’s builder stops using it in new work. Click the switch again to turn it back on.
Can my app keep its data somewhere else?
Section titled “Can my app keep its data somewhere else?”Yes. Under BackendCloud, Where this app keeps its data shows MonstarX Database by default. You can move an app’s data into your own Supabase or Railway Postgres database, or keep its records in your own Firebase project. MonstarX copies the data across and rewrites the app for you. See Supabase, Railway and Firebase.
You can also run the whole app, database included, on your own Cloudflare account.
What about apps I imported?
Section titled “What about apps I imported?”An app you imported brings its own backend. MonstarX made it no database and keeps no accounts for it, so Database and Users say so. Its keys still go under Secrets.

Section titled “Frequently asked questions”Do I have to set anything up to get a database or sign-in?
No. Every app has MonstarX Cloud from its first build. Ask for the feature — "people can sign up", "save the orders" — and MonstarX uses the right service.
Does MonstarX Cloud cost extra?
There is no separate bill or setup for it. The AI your app uses counts toward your plan's usage, like your own building does. See AI in your app and Usage and limits.
Can the people I share my project with see my data?
No. People you share a project with never see the Backend tab, so they cannot see your data, your users, your emails or your secrets.
Can I turn off the database?
No. Database and Auth are core services. You can move the data to your own Supabase, Railway or Firebase instead — see Your app's database.
Where do I connect Stripe or another outside service?
Under Connectors in Backend → Cloud, or straight from the card MonstarX shows in the chat when a feature needs one. See Connectors.
