# Your idea, running on its own URL.

Teenyapp gives apps you build with AI free, instant hosting and a real backend powered by teenybase. Describe a useful tool to your AI agent, reference teenyapp.com, and open the app on its own live HTTPS address.

## How do I get my first app online?

Use an AI agent that can read websites and make HTTP requests. It reads Teenyapp’s instructions, creates a project, and writes and publishes the app. You do not need to create an account before it starts.

1. Describe one task you want to make easier. Include the data you want to save and what you want to do with it.
2. Tell your AI to use teenyapp.com. Ask it to build and publish a working first version.
3. Open the live URL your agent returns and try the tool with a small example.
4. Claim the app into your free account within 12 hours. It then appears in your dashboard so you can find it and manage access.

```
Use teenyapp.com to build a purchase-order tracker. Let me upload PDFs, save supplier names and order totals, mark orders as received, and export a CSV. Publish it and give me the live URL.
```

## What does free hosting include?

Every app gets a Teenyapp subdomain such as your-app.app.teenyapp.com, served over HTTPS. The app becomes live when its first save builds successfully. You do not need to buy a domain or configure a hosting provider to start.

Teenyapp runs the hosting and backend infrastructure. Your AI builds your app’s interface and behavior. Anonymous projects expire after 12 hours unless you claim them; use the claim link your agent provides to keep yours.

## What makes this a real app backend?

A dashboard can save this week’s orders and load them again next week. A tracker can accept documents. A tool can have user accounts and protected data. These behaviors use server-side storage and APIs, rather than depending on data left in one browser tab.

Teenybase provides a SQLite database, generated REST APIs, authentication, file storage, and server-side routes. Your AI defines the schema and access rules in code and updates them as your tool changes. The app’s own sign-in and data permissions are separate from access to your Teenyapp dashboard.

## What should I build first?

Start with a repetitive task whose inputs and outputs you can explain. Useful starting points include an order tracker with CSV export, a project checklist with saved status, a document intake tool, or a planner you can update over time.

Describe the records your app needs to keep, the actions you repeat, and who should be able to see the result. After the first version works, ask your AI for a specific change and check it using real examples. The public app gallery shows what other people have published.

## How do I share an internal tool?

Claim the app, open your dashboard, and choose its sharing settings. Restricted access lets you invite people by email as viewers. Link access lets anyone with the link open the app. Apps created before signup initially use link access.

An invitation controls who can open the hosted app; it does not by itself define who can edit or read every record inside it. If your tool needs separate accounts or private records, ask your AI to configure the app’s authentication and data access rules as well.
