Quizzes and challenges with real scoring
Question banks, timers, attempts and results stored per player instead of lost when the tab closes.
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.
Leaderboards that survive the session
Scores are records, so the ranking is the same for everyone and still there tomorrow.
Interactive pieces that run in the browser
Campaigns, advent calendars, spin-to-win, personality tests — a link you can send, not a file to install.
Prizes, capture and follow-up
A game that collects a lead, sends a coupon and reports how many people finished it is a marketing tool, not a toy.
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.
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 quiz app for a marketing campaign. Multiple-choice questions with a time limit per question and randomised order; the player enters a name and an email before starting; the score is saved and shown on a public leaderboard of the top twenty; whoever finishes gets a discount coupon by email; and there is an admin area where I add questions and see how many people started, finished and dropped out on which question.

A template is a working app with data already in it. Open one, make it yours, publish it under your own account.

Describe it. See it running. Publish it to the store.
Free to start, no credit card. You subscribe when you want your own domain without the badge or your app in the stores, and on the Builder plan you take the code with you if you ever want to.
