AI App Builder

The AI app builder that turns one prompt into a web app

Willow is an AI app builder that turns a plain-language description into a running full-stack web app. Write what you want to build, say a point-of-sale app with sales reports, and Willow builds the interface, backend, and database, with a live preview.

How Willow works as an app builder

Unlike drag-and-drop app builders, Willow never asks you to place components one by one. The flow is simple:

  • Write your app idea in the prompt box, in English or Indonesian.
  • The AI agent designs the pages, APIs, and database schema, then writes the code.
  • The app runs right away in the live preview, ready for you to try.
  • Ask for changes in the chat: new colors, new features, or a better flow.
  • Download the full source code when your app is ready.

An app builder that produces real code

Many no-code app builders lock your app into their platform. Willow produces React, Hono, and PostgreSQL code that you can download and run anywhere. You own all of the source code, including the database schema.

Because the output is real code, apps built with Willow can keep growing with a developer, move to your own server, or become the foundation of a bigger product.

Examples of apps you can build

Willow users have already built many kinds of apps, including:

  • Point-of-sale (POS) and inventory apps for small businesses.
  • Online stores with a catalog, a cart, and an admin dashboard.
  • Academic information systems for coursework and final-year projects.
  • Landing pages and company profiles with a contact form.
  • Internal dashboards, booking apps, and task managers.

Pay as you go, no subscription lock-in

Willow takes one-time card payments. Pro runs for 30 days and never renews on its own, so you only pay when you need more.

Frequently asked questions

What is an AI app builder?

An AI app builder is a platform that creates apps from a plain-language description. Willow takes your prompt, then the AI writes the frontend, backend, and database code and runs the app in a live preview.

Is Willow free?

You can start building apps for free. For more credits and more workspaces, the Pro plan starts at $8.

Can I download the apps I build with Willow?

Yes. All of the source code, including the database schema, downloads as a zip file starting at $1 and runs on any server.

How is Willow different from a regular no-code app builder?

A regular no-code app builder makes you assemble components by hand and locks the app into its platform. Willow works from a prompt and produces real code that is entirely yours.

Can Willow build mobile apps?
