Registration with tiers and a cap
Ticket types with a price, a tier by date and a limited quantity. When they run out, they run out in the database rather than in someone's judgement.
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.
A ticket with a QR code
Issued on payment, sent by email and opened on a phone. Each one is unique and can only be scanned once.
Check-in at the door
A scanning screen on the team's phone: scan the code, confirm the name, mark attendance. A second scan of the same code raises a flag.
Programme and live announcements
Talks with times and rooms, favourites for each attendee, and push for a last-minute change, which is when an announcement actually matters.
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.

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 an app for a two-day event. Ticket types with a price, a tier by date and a limited quantity, paid by card; registration issues a ticket with a unique QR code, sent by email and opened on a phone; the team has a scanning screen that confirms the name, marks attendance and warns when a code has already been used; a programme with talks, times, rooms and speakers, and attendees marking the ones they want to attend; push announcements to everyone or only to people who marked a given talk; a public event page with the programme and registration, written to be found by search engines; and an admin area only I can see, with registrations by ticket type, revenue per tier, attendance per day and the most-saved talks.

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

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.
