Quizzes and challenges with real scoring
Question banks, timers, attempts and results stored per player instead of lost when the tab closes.
Quizzes, challenges, scoreboards and interactive experiences that run in the browser.
Not everything you build is a business app. Quizzes, scoreboards and interactive pieces run on the same stack, publish to the same URL and install on a phone like any other app.

What gets built
Not a feature list. These are the apps people actually describe, and what the platform hands back when they do.
Question banks, timers, attempts and results stored per player instead of lost when the tab closes.
Scores are records, so the ranking is the same for everyone and still there tomorrow.
Campaigns, advent calendars, spin-to-win, personality tests — a link you can send, not a file to install.
A game that collects a lead, sends a coupon and reports how many people finished it is a marketing tool, not a toy.
Included
Database, login, payments and publishing are part of the platform, not a list of services you go and wire up afterwards.
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.
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.
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.
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.
Titles, metadata, sitemap, structured data and social images are generated with the app. Pages get found instead of only being linked.
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
Three steps, and the second one is the one people do not believe until they watch it.
Say what the app does and what it has to remember. No diagram, no schema, no naming a single framework.
Screens, data models, login and payments appear while you read. Anything you do not like, you say so and it changes.
Live on your domain in seconds, with version history behind you. Tuesday's conversation is Tuesday's release.
Start here
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.
Ready to start from
A template is a working app with data already in it. Open one, make it yours, publish it under your own account.
Questions
That is what most of this category is for. The game captures a lead, sends the coupon and reports where people dropped out — and it publishes to your own domain, so it works as a campaign landing page rather than a link to someone else's tool.
Keep looking
Most apps end up sitting between two categories. Nothing stops you from asking for both in the same paragraph.
Catalog, cart, checkout, coupons and subscriptions. Card and Pix built in, with orders and customers in your own database.
Availability per professional, confirmation, reminders and check-in — the classic agenda, without the spreadsheet.
Profiles, feeds, posts, comments and directories, with ownership rules per record.
Lessons, modules, student progress and a paywall, with video and files hosted on the platform.
Service desks, internal back offices, order tracking, checklists and dashboards for your team.
Pipelines, leads, proposals and follow-ups — a CRM shaped like your process instead of someone else's.
Onboarding, requests, approvals, documents and signatures — the internal flows that live in email today.
Ledgers, budgets, expense control and financial dashboards, with charts that read from your own records.
Directories, forms, catalogs, internal portals — anything you can describe in a sentence.
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.
