How to build, publish and run your app on Fabapp.

Start here
From the first prompt to a published app, in minutes.
Get to know the Studio
Where each thing is. The list is complete.
When something goes wrong
The common symptoms and the cause of each.

Getting started

Creating your first app
From what you type to the app online. It takes minutes, and the Free plan walks the whole path without asking for a card.
Getting to know the Studio
Where each thing is, so you stop looking for it. This list is complete: if it is not here, it does not exist.

Building

Writing good prompts
How to describe what you want so the AI builds the app you pictured, and not one that resembles it.
Asking for changes without breaking what works
The most common fear once you have a running app: ask for one adjustment and get a different app back. This guide is about why that almost never happens, and what to do the times it does.
Undoing: version history
Every edit the AI applies becomes a saved version. Nothing you ask for is irreversible, and going back costs no credits.

Your app’s users

Sign-up and login in your app
How people create an account and get into the app you published. This is about the users of your app, not about your own Fabapp account, which is a different thing and lives in your profile.

Publishing

Publishing your app
Going live, going offline, and the difference between what you see and what the world sees.
Using your own domain
Point a domain you already own at your app, with an SSL certificate issued automatically.
Publishing your app on the App Store and Google Play
The app you already published on the web becomes a real native app, with push and camera, and goes to the stores under your own developer account. Setting it up takes about 10 minutes; the first publication takes 1 to 2 days, because of the stores' review.
Connecting your Apple and Google accounts
The credentials the platform uses to sign, submit and notify on your behalf, where to generate each one, and the classic mistake behind each. They are stored encrypted and never come back to the screen.

Payments

Selling subscriptions inside the app
Inside the app installed from a store, the store does the charging, not your gateway. This guide covers how to tie each of your app's plans to an App Store or Google Play product, and why the subscribe button sometimes does not show up.

Integrations

Activating integrations
Where to switch on the outside services your app uses (payments, maps, SMS, WhatsApp, notifications), what each state of the card means, and which guide to follow for each provider.
Payments: Stripe, Mercado Pago, Pagar.me and Hotmart
How to connect the gateway that receives the money from your app's sales and subscriptions, with test keys first and production keys after.
Google Maps
How to connect a Google Maps key so the app suggests addresses while the person types and stores the location (latitude and longitude) of each address.
WhatsApp
How to connect your Meta WhatsApp Cloud API account so the app sends WhatsApp messages: confirmations, reminders and notifications.
Email with your own domain
How to make your app's emails go out from an address on your domain, such as contact@yourcompany.com, instead of the platform's sender.
SMS with Twilio
How to connect your Twilio account so the app sends SMS (alerts, reminders, confirmations) and to unlock login by phone.
Connections by authorization: Shopify, Meta and Google Workspace
How to link to the app an account of yours where you authorize access in the browser, instead of just pasting a key: your Shopify store, your Facebook pages and your Google account.
Notion, Airtable and Mailchimp
How to connect the three tools that work with a single token: the app creates pages in a Notion database, reads and writes records in Airtable and subscribes contacts to a Mailchimp list.
Webhooks and notifications: Webhook (outgoing), Slack, Discord and Telegram
How to make the app notify you or your team outside of it (a Slack channel, a Discord server, a Telegram group) and how to send data to an automation of yours, in Zapier, in Make or at an address of your own.
Backend functions
What the functions that run on the server are, when your app needs one, and what to do when your plan does not include this feature.

Code

Command line and keys
Bring your project's definition to disk, run the app on your own machine, and publish it back without leaving the terminal.

Account

Credits: what spends them and what does not
Two separate currencies, what each one pays for, and why you do not pay for the AI's mistakes.

Troubleshooting

The most common symptoms, what usually causes each one, and what to do. In the order they show up.
