Trontra Apps

An AI app builder for real businesses

Ship an app you can run a business on. Own it outright.

Trontra Apps turns a short brief into a written spec, then into a real Next.js and Supabase app with login, payments and email. Every build is checked before you see it, and publishing waits until the app is safe to take money.

How it works

Spec first, then code. Checked before you see it.

There is no blank prompt box. You describe the business, approve what the app is, and every change after that is built, verified and shown in a live preview.

  1. 01

    Brief

    Answer five questions: what it is, who uses it, what they must be able to do, how it makes money and which services it needs.

  2. 02

    Spec

    The AI writes a plain-language spec of pages, roles, data and flows, with open questions for you. You edit it and approve it. Code follows the spec, not the chat.

  3. 03

    Build

    The builder edits a production template in a private sandbox. Nothing reaches your preview until typecheck, lint, build and tests pass.

  4. 04

    Ready

    Launch Readiness scores security, payments, email, legal, SEO, speed and more. Most fixes are one click. Blocking items must pass before you publish.

  5. 05

    Publish

    Go live on your own trontra.app address or your domain, with versions and one-click rollback.

After the first build, ask for changes in plain words or pin a comment on the preview. Each change is a new version you can roll back.

Launch Readiness

Ready to take money, not just ready to demo.

Every app carries a readiness score, re-checked after each build. It covers what usually goes wrong after launch, not just whether the page renders.

  • Security

    Row-level security on every table, headers and CSP, no secrets in the code

  • Payments

    Stripe connected, webhook registered and verified, idempotent

  • Email

    Sending domain verified, auth emails sent from you

  • Legal

    Privacy, terms and contact pages, linked in the footer

  • SEO

    Metadata, sitemap, robots and social images on every page

  • Performance

    Lab speed scores on key pages

  • Accessibility

    No critical axe violations, labelled forms

  • Reliability

    Error monitoring, health route, friendly error pages

  • Domain

    TLS, HSTS and a www redirect on your domain

Publishing waits until every blocking check passes. Most fixes are one click: the builder makes the change and checks it again. Developer mode can publish past a check with a written reason, which is kept in the app’s history.

Ownership

Yours, by construction. Leaving is a feature.

Export is free and tested. There is no eject step and no Trontra runtime inside your app.

Your code

Every version is a real Git commit. Link a GitHub repo and each version is pushed to it. Pushes you make there build too.

Your hosting

Take ownership moves the live app into your own Vercel account, domains included, with no downtime. The old address redirects for 30 days.

Your data

Your app runs on your own Supabase project, connected in one click. It talks to its database directly; Trontra never sits in the middle.

Your next developer

Every repo ships with an AGENTS.md, so Cursor, Claude Code or a person can pick up exactly where the builder stopped.

Agents inside

Apps with an agent inside.

Put one of your Trontra agents on your app as a chat. It answers from your instructions and can use read-only tools your app provides, only for what the signed-in visitor may see. Its conversations use your workspace credits.

Honest scope

One stack, done properly.

Every app starts from a production template Trontra maintains, so quality comes from the template and the checks, not from luck.

  • Next.js

    App and API

  • Supabase

    Database, auth, storage

  • Stripe

    Checkout and subscriptions

  • Resend

    Email

What it does not build yet: mobile apps, games, or apps on other frameworks. Hosting runs on Vercel today, with Cloudflare to follow.

Questions

Before you start building

01

Do I need to know how to code?

No. Guided mode never shows code: you work with the spec, the preview and the readiness list. Developer mode adds the file tree, Git, logs and model choice when you want them.

02

What kinds of apps can it build?

Web apps for a business: client portals, booking and scheduling, memberships and subscriptions, internal tools, marketplaces in time. It builds one stack, Next.js with Supabase, Stripe and Resend, and builds it well. It does not build mobile apps or games.

03

Can I take the app somewhere else?

Yes, and it is free. Link GitHub and every version lands in your repo. Take ownership moves the live app into your own Vercel account with its domains. Nothing in the code depends on Trontra.

04

How is this different from other AI app builders?

Three things. You approve a written spec before any code is built. Every change is checked before it reaches the preview. And publishing is gated on Launch Readiness, so the app is safe to charge customers before it goes live.

05

Who can see my keys and customer data?

The AI never sees secret values, only whether a key is set. Keys are encrypted at rest and injected at build and run time. Your customers' data lives in your own Supabase project.

06

Can I put an AI agent inside my app?

Yes. Pick one of your Trontra agents and it appears as a chat on your app. It can use read-only tools from your app, such as finding the right page, and answers only for what the signed-in visitor may see.
