Describe an app. Get a working app.

NanoNear App Builder turns a plain description into a real web app: pages, forms, charts and saved data. You see it running straight away, keep changing it by chatting, and publish it with its own link when you are happy.

What it solves

Small businesses need booking pages, order forms, dashboards and little internal tools all the time. A developer takes weeks and costs thousands; generic website builders cannot do the logic.

Who uses App Builder

  • Small businesses that need a form, page or tool this week
  • Agencies prototyping for clients
  • Founders testing an idea before hiring developers
  • Teams replacing spreadsheets with a simple app

How it works

  1. Describe it

    Write what the app should do, like you would to a developer. Or start from an idea: landing page, booking form, dashboard, tracker.

  2. Watch it build

    The AI writes the app and it opens in a live preview on desktop, tablet and phone sizes.

  3. Change it by chatting

    "Make the header blue", "add a search box", "save the bookings". Every change is a new version you can go back to.

  4. Publish

    One click gives the app its own link. Download the code any time.

What you can do with App Builder

Everything below works today. Where a feature needs a particular plan, it says so.

Building

From a sentence to a working app.

  • AI that writes real code

    React and Tailwind, or plain HTML, written by Claude, the model most leading app builders use for code.

  • Live preview

    The app runs next to the chat as it is built, with desktop, tablet and phone sizes.

  • "Fix it" button

    If the preview shows an error, one click sends it back to the AI to fix.

  • Edit the code yourself

    Every file is yours to open, change and save, alongside the chat.

Running

Apps that do something, not just look nice.

  • Built-in data

    Forms, lists and trackers can save records without any database setup, and you can see what was saved.

  • Publish with one click

    Your app gets its own link on your NanoNear workspace. Update it whenever you publish again.

  • Version history

    Every change is kept. Restore any earlier version in one click.

  • Download the code

    A ZIP with the source files and a single-file build you can host anywhere.

Questions about App Builder

How much does NanoNear App Builder cost?

$34.99 a month per workspace, with 250 AI messages a month, up to 50 apps and 20 published apps. There is a 7-day free trial with 25 messages and no card.

Which AI model does it use?

Claude by Anthropic, the model family most leading AI app builders use to write code. You can choose Smart for new apps and big changes, or Fast for quick edits.

What kind of apps can it build?

Web apps that run in the browser: websites and landing pages, booking and order forms, dashboards and charts, trackers, calculators and internal tools. It does not build native phone apps or apps that need their own server.

Is there a login system or a database?

Apps can save data with the built-in data store, which anyone using the published app can read and change. There is no user login inside generated apps yet, so do not use them to collect passwords or payment details.

Do I own the code?

Yes. Download it any time as a ZIP, including a single-file version you can upload to any web host.

What counts as an AI message?

Each message that changes or answers about your app, once the AI has answered successfully. Failed or stopped answers are not counted.
