Introduction

Highwind is an AI app builder. You describe the website or app you want in a few sentences, an agent writes it for you, and you watch it come together live in a preview. Then you improve it by chatting, as you would with a colleague, and put it online in one click on its own address. No code to write, but the code is there, standard and readable, if you want to look at it.

The core loop

Section titled “The core loop”

All of Highwind fits in four steps, which you repeat as many times as you like.

  1. You describe your idea. For example: “A website for a yoga studio in Lyon, with the class schedule and booking”. A few sentences are enough; you can attach a screenshot or a mockup.

  2. The agent builds an app that runs. It writes the code in an isolated environment, checks that it compiles and that the preview shows without errors. You see the app appear section by section while it works.

  3. You iterate in the chat. “Use warmer colors”, “add a pricing page”, “the button should open the form”: each request creates a new version, and you can go back to any of them. For small touch-ups (a text, a color, a font), Design mode lets you edit directly, without the agent and without credits.

  4. You publish. You pick a .highwind.site address and click Publish: the app is online, over HTTPS. You update it whenever you want.

What you can build

Section titled “What you can build”

Anything that fits in a web app: a site people open in a browser, on desktop as well as on mobile.

Websites and landing pages

A shop’s showcase site, a product launch page, a portfolio, a blog, an event page with schedule and registration.

Tools and dashboards

A KPI dashboard, a kanban board, a planner, a calculator, a converter, an internal tool for your team.

Apps with accounts and data

User sign-up and sign-in, data saved in a database, files uploaded by users: enough to make a real small SaaS.

Apps wired to your services

A contact form you receive by email, sign-ups added to Google Sheets, payments with Stripe, an AI feature with your OpenAI or Mistral key, A/B tests with Kameleoon… more than 50 connectors.

To start even faster, the gallery offers eight complete templates (SaaS launch, portfolio, restaurant, online store, dashboard, blog, event, task board) that you get instantly, without spending any credits.

What’s under the hood, in plain words

Section titled “What’s under the hood, in plain words”

You don’t need any of this to use Highwind, but it helps to understand what you get.

  • The agent is an artificial intelligence model (currently provided by OpenAI) with tools around it: it reads and writes the project’s files, installs libraries, checks its work and fixes its own errors. It replies in the language you write in.
  • The code is React, TypeScript, Vite and Tailwind CSS: the most widely used tools for building web apps. It is readable, editable in the built-in editor and downloadable as a ZIP.
  • Each project has its own isolated environment (a “sandbox”), located in the European Union. That’s where the live preview runs.
  • The design relies on a theme: a few colors by role (background, text, primary color, accent…) and two fonts. Changing the theme changes the whole site at once.
  • When the app needs it, the agent adds a server (/api routes to call a service with a secret key or send an email) or offers you a backend: a database with user accounts and files, hosted in Paris.
  • Publishing puts the app online at your-app.highwind.site, a domain kept separate from the platform for everyone’s safety.

Who it’s for

Section titled “Who it’s for”
  • You don’t code: founder, freelancer, nonprofit, local business, marketing team. You describe, adjust by chatting, and publish.
  • You prototype: a product manager or designer who wants to test an idea with a real clickable app, from a Figma mockup or a Notion spec.
  • You code: you save the first hours of a project and keep standard code you can edit by hand or download as a ZIP.

Limits to know about

Section titled “Limits to know about”

Highwind is young and in private beta. Here is what you should know before you start.

  • Invite-only access: you need an invitation to sign in. Otherwise, you can join the waitlist.
  • Daily credits: during the beta it’s free, with 5 credits per day and at most 30 per month. A new app usually costs 2 to 4 credits, a small change less than one credit. See Credits.
  • Web apps only: no native app to install from the App Store or Google Play (but apps are designed for mobile).
  • One request at a time: the agent works on only one of your projects at a time.
  • No custom domain yet: apps are published on .highwind.site. See Custom domains.
  • No GitHub sync and no multi-person editing on a project for now.
  • Apps with accounts: no confirmation emails or password reset yet for your apps’ users; one backend per account during the beta.
  • AI can make mistakes: review what it produces. Every change is a version, and you can always go back.
