FAQ

Getting started

Do I need to know how to code?

No. You describe what you want in your own words and ask for changes by chatting. For small touch-ups (text, colors, fonts), Design mode works with the mouse. The code is there if you want to look at it, never required.

How do I get access to Highwind?

Highwind is in private beta, invite-only. If you received an invitation, sign in with that email address. Otherwise, request an invite from the home page (Private beta: request an invite): you’ll get an email as soon as your spot is ready.

What can I build?

Anything that fits in a web app: showcase sites, landing pages, portfolios, blogs, online stores, event pages, dashboards, internal tools, calculators, and apps with user accounts and a database. See Introduction and the example requests.

How long does it take to create an app?

A new app usually takes one to two minutes. You don’t wait in front of a blank screen: the app shows up in the preview after a few tens of seconds, then fills in section by section. A change usually takes less than a minute. And a template is ready instantly.

Can I create a mobile app?

Highwind creates web apps: they open in the browser and are designed for mobile from the start (the preview has Desktop, Tablet and Mobile views). It doesn’t, however, create native apps to publish on the App Store or Google Play.

Code and technologies

Which technologies does Highwind use?

Apps are written in React and TypeScript, with Vite and Tailwind CSS, React Router for navigation and lucide-react icons. When needed, the agent adds a server (/api routes, running on Cloudflare Workers) and, if you enable it, a Supabase backend (Postgres database, user accounts, files). The agent itself currently relies on an OpenAI model.

Do I own the code?

Yes. You keep your rights to your messages, your images and your apps’ code. It’s standard, readable code that you can edit in the built-in editor or download.

Can I download the code?

Yes, at any time: the Download the code (.zip) button (download icon) at the top of the editor. The ZIP contains the sources of the version shown, including the database migrations if the app has a backend. Secret keys are never included. It’s a standard Vite project you can open in your own editor.

Can I edit the code by hand?

Yes. The Code tab opens a full editor (the one from VS Code): edit a file, then Save or Ctrl + S. The preview updates, a new version is created and the agent is told which files you changed. You can also create, rename and delete files. See Code.

Can I sync my project with GitHub?

Not yet. In the meantime, you can download the code as a ZIP at any time.

Can I import a Figma design?

Yes, if you connect Figma as a context source (Connectors page, with a personal access token). Then paste a frame link in your message: the agent reproduces it faithfully. See Figma. You can also simply attach a screenshot of the design as a reference image.

Credits and pricing

What are credits?

Credits measure the agent’s work. Each request is counted according to the work actually done, to a tenth of a credit: a small change costs less than one credit, a complete new app 2 to 4 credits, and a request is capped at 12 credits. A request that fails isn’t counted. See Credits.

How much does Highwind cost?

During the private beta, Highwind is free: no payment method is required. Each account gets 5 credits per day, up to 30 per month. Paid plans will come after the beta; what they include and their prices will be announced in advance.

What happens when I run out of credits?

You can’t send messages to the agent until the refill, every night at midnight (UTC). Design mode, code editing, versions and publishing remain available, and your published apps stay online.

What’s free?

Everything that doesn’t make the agent work: starting from a template, Design mode edits, code editing, viewing and restoring versions, publishing and hosting your apps.

Do connectors cost anything?

Highwind doesn’t charge for connectors. The services you wire up with your own key (Resend, Stripe, OpenAI…) bill you directly at their own rates. Google Sheets connects with your Google account, without a key.

Data and security

Is my data safe?

Each project runs in its own isolated environment, located in the European Union.
Apps’ databases are hosted in Paris, and access rules are enforced: each user of an app only sees their own data. A critical security hole blocks publishing.
The API keys you add are encrypted, never shown again, never shown to the agent nor sent to visitors’ browsers.
Published apps live on a domain separate from the platform (highwind.site), over HTTPS.

See Security and Privacy.

Are my projects used to train an AI?

No. To build your app, your messages, images and the project’s code are sent to the AI model provider (OpenAI), only to generate the reply. Highwind does not use your projects to train models. Still, avoid putting sensitive information in your messages.

Who can see my app?

Until it’s published, nobody but you. Once published, anyone can open it at its address. You can unpublish it at any time from the Publish menu or Project settings → Publishing.

Can I delete my account?

Yes: Settings → Account → Delete my account. Everything is permanently erased: projects, versions, live apps (taken offline right away), databases and their users’ accounts. Download your apps’ code first if you want to keep it. See Delete your account.

App features

Can my app have user accounts and a database?

Yes. Enable the project’s backend (the agent offers it when useful, or Project settings → Backend): Highwind creates a database hosted in Paris, and the agent adds sign-up, email and password sign-in, data storage and file uploads. During the beta: one backend per account, no confirmation email or password reset yet. See Database.

Can my app send emails, take payments, use AI?

Yes, thanks to connectors: more than 50 services (Resend, Brevo, Stripe, Mollie, OpenAI, Mistral, Slack, Airtable…) called by your app’s server with your own key. Mention the service with @ in your request. See Connectors.

Can Highwind create my site’s images?

Yes. When the design needs photos or illustrations, the agent generates them in the site’s style (a few images per page, never for icons or logos). You can also upload your own images, which always come first. See Generated images.

Can I run A/B tests?

Yes, with Kameleoon: the agent installs Kameleoon in your app, and the editor’s Kameleoon panel lets you create experiments, variations and goals, and follow the results. See Kameleoon.

Will my site rank well in search engines?

The agent fills in each app’s title, description and sharing tags, and on publishing Highwind adds a preview image taken from a screenshot of the app. Apps are single-page applications (SPA): server-side rendering and advanced SEO aren’t offered yet.

Publishing and languages

Can I use my own domain name?

Not yet: apps are published on a .highwind.site address (for example my-app.highwind.site), over HTTPS. Custom domains are planned. See Custom domains.

How long does my app stay online?

As long as you don’t unpublish it or delete the project. Published apps don’t use credits.

Which languages does Highwind work in?

The interface is in French and English (Settings → Preferences → Language, or the FR / EN switcher). The agent replies in the language you write in. The site you create can be in any language you like: just say so in your request, or ask for a bilingual version.

Can several people work on a project?

Not yet: a project belongs to a single account.

Can I undo a change?

Yes. Every request, every editing session and every code save creates a version. Click the version badge at the top of the editor to view an old version and restore it. See Versions.
