Use cases

Everything else

Directories, forms, catalogs, internal portals — anything you can describe in a sentence.

The categories are a way to browse, not a limit. If you can describe what the app should do and what it should remember, it can be built here.

What gets built

Four things you could have working this week

Not a feature list. These are the apps people actually describe, and what the platform hands back when they do.

01

Directories and searchable catalogues

Listings with the fields your niche actually filters by, public pages for each entry, and search that reads from the data.

02

Forms that become records

Registrations, applications, surveys and intake, with validation, files and a place where the answers live afterwards.

03

Portals for clients or members

A private area where each person sees their own documents, invoices, status or history — and nobody else's.

04

Whatever you can describe in a paragraph

If you can say what the app does and what it has to remember, that is a specification the platform can build from.

Included

The parts nobody wants to build twice

Database, login, payments and publishing are part of the platform, not a list of services you go and wire up afterwards.

A real database, not a form dump

Every screen reads and writes models you can open, query and export. The data is a database of yours from the first minute, not a spreadsheet the app pretends to read.

Login for your own users

Email, magic link and Google sign-in, with roles and per-record ownership enforced by Postgres itself. A badly written screen cannot become a leak, because the database answers empty.

Payments that land in your account

Stripe, Pagar.me and Mercado Pago connect once. Card, Pix, boleto and subscriptions, with the card fields rendered by a hosted vault your app never touches.

Web, installable, and in the stores

One project published three ways: your own domain, an icon on the phone straight from the browser, and a signed binary submitted under your own store account.

Found in search, and by the models

Titles, metadata, sitemap, structured data and social images are generated with the app. Pages get found instead of only being linked.

React code you can take with you

Real React, edited line by line or by clicking the element on screen, exported as a ZIP or pushed to your GitHub. No lock-in you have to negotiate your way out of.

How it works

From a paragraph to a published app

Three steps, and the second one is the one people do not believe until they watch it.

Describe it in plain language

Say what the app does and what it has to remember. No diagram, no schema, no naming a single framework.

Watch it get built

Screens, data models, login and payments appear while you read. Anything you do not like, you say so and it changes.

Publish, then keep changing it

Live on your domain in seconds, with version history behind you. Tuesday's conversation is Tuesday's release.

Start here

A prompt you can paste right now

This is a complete first message, not a slogan. Paste it, change the nouns to yours, and you have an app to react to instead of a blank page.

Build a directory app for local businesses. Each listing has a name, category, address with a map, opening hours, photos and contact details; visitors search by category and neighbourhood and open a public page for each business; business owners claim and edit their own listing after signing in; and there is an admin area to approve new listings and see the most viewed ones.

Questions

Frequently asked questions

The categories are a way to browse, not a limit. If you can describe what the app does and what it has to remember, it can be built here — most real apps end up sitting between two categories anyway.

Describe it. See it running. Publish it to the store.

Free to start, no credit card. You only pay when you want to publish under your own brand, and you take the code with you if you ever want to.
