No-code app builder

Anyone can build their own app.

Describe your idea in one sentence. Yatsury builds a real app: your members book, post and sign up, and the app tracks every step on its own.

  • Free to create
  • No commitment
  • Live via a link right away

For people with an idea.
Not a developer.

Founders, students, creators, nonprofits: if you have the idea, you can have the app.

  1. 01

    You have an app idea.

    It's been on your mind for months. Yatsury turns it into a real app, with no agency and no quote.

  2. 02

    You've never written code.

    Every step is explained simply. You can't skip a step, and you can't get lost.

  3. 03

    You want to test it first.

    Create for free, show your app to people around you, and only pay the day you publish it.

Four steps.
Zero lines of code.

A real app.
Not a website in a phone.

Yatsury doesn't just stack pages on top of each other. It thinks about what your users do, and the app handles it for you.

  1. 01

    Everything follows its steps.

    A basket goes from open to full, an order from sent to ready, a match from to play to confirmed. Spots count themselves. Nothing to keep an eye on.

  2. 02

    Everyone has their own space.

    My bookings, my shifts, my scores: each member finds what matters to them. You run the rest from your organizer space, with your code.

  3. 03

    The app brings people back.

    A reminder the day before a shift, “your order is ready”, new baskets online: follow-ups are built in from the start.

  4. 04

    Its own welcome and its own style.

    Every new member is greeted by first name and guided to their first action. And every app has its own style, chosen for it: native, editorial, minimal or soft. You can change it in one click.

One sentence. One app.

Farm baskets, a padel tournament, a community garden, nonprofit volunteers, a food truck: Yatsury built each of these apps from a single sentence. They're live: the screens are real screenshots, and you can try them.

Frequently asked questions.

Do I need to know how to code?

No. Yatsury is built for beginners: you describe your idea, Yatsury builds the app, then you edit it in plain language or ask the AI for a change in one sentence.

Why a subscription?

An app that's live has to stay hosted, up to date and compatible with every new version of iPhone and Android. Instead of a large upfront cost, you pay a few euros a month, only once your app is live, with no commitment. Pay yearly and get two months free.

What's free?

Everything you need to create and test your app: features, design, content, preview. During the beta, publishing as a web link is free too; after that, the subscription only starts once your app is live.

Do I own my app?

Yes. Your app, your content and your users' data belong to you. Yatsury hosts them for you, never sells or transfers them, and deletes them if you delete your account.

Can I publish on the App Store and Google Play?

Soon. Store publishing is in the works: we'll do it with you, step by step. In the meantime, your app is live through a link and can be installed on the home screen. Leave your email below to be notified when it opens. Apple and Google charge their own fees.1

What is an AI key, and do I need one?

No, it's optional. An AI key is a personal code provided by an AI service (Claude, ChatGPT, Gemini, Mistral…). Without a key, AI is included in the subscription. With your own key, the provider bills you directly for actual usage, often a few euros per app, and your subscription costs €2 to €4 less per month.

Which AI models are supported?

Claude (Anthropic), ChatGPT (OpenAI), Gemini (Google) and Mistral. We only enable models we've tested on app creation, to guarantee a reliable result; more are on the way.

How is this different from a website builder?

A website builder puts pages together. Yatsury builds what your users do: book, request, sign up, join a waitlist. Each item follows its steps, everyone has their own space, and you manage it all from your organizer space.

My idea doesn't look like any of the examples.

That's expected: describe it in your own words, and the studio starts from your description. The examples are only starting points.

What an agency would charge thousands of euros for, open to everyone. You bring the idea, Yatsury takes care of the rest.

One screen for everything.

Every change shows up in your app instantly.

Nothing is set in stone.

Undo, go back to an earlier version, try something else.

AI by your side.

Ask for a change in one sentence. Don't like it? Undo.

Connect the tools you love.

Payments, AI, maps, calendar, stores: Yatsury connects your app to the services you already know. Every connection is guided, with nothing technical.

See example apps

Your AI, your choice.

By default, AI is included: nothing to set up. Already have a key? Connect it and pay €2 to €4 less per month for your subscription.

Your key is encrypted, used only for your app, and can be deleted at any time.

Eyal Ouaknine, founder of Yatsury Studio

Anyone can build a website. Almost no one can build an app.

It all started with that observation. For a website, anyone is spoiled for choice: Wix, Shopify, Squarespace. In one evening, it's live. For a mobile app, there's almost nothing simple. You need an agency and several thousand euros, or tools made for developers.

I launched my first project at 15 and I've already published an app on the App Store. I know how many invisible steps separate a good idea from an app that works. Most people give up right there, for lack of a tool, not an idea.

I created Yatsury so that making your own app becomes as simple as making your own website, and so that it's open to everyone.

Terms and conditions

This translation is provided for convenience; the French version prevails.

Provisional beta version. The final terms of sale will be published when payments open.

1. Purpose

Yatsury Studio is an online service that lets anyone, even a beginner, create a mobile app without coding, then publish it as a web link or as an iPhone and Android app.

2. Access to the service

Creating and testing an app is free. The service is in beta : features may change and occasional interruptions are possible.

3. Prices and payment

Publishing an app requires a subscription with no commitment, AI included : €9 per month for the web link, €24 per month for the iPhone and Android app, or €90 and €240 per year respectively. Release on the App Store and Google Play is charged €49 with the monthly subscription, only once the app has been accepted by Apple or Google, and is free with the annual subscription. With their own AI key, the user pays €7 and €20 per month (€70 and €200 per year) and pays for AI usage directly to their provider. The subscription can be cancelled at any time from the account, effective at the end of the paid period ; the app is then taken offline. Beta members keep the launch price as long as their subscription remains active. Payment is not yet open during the beta. Apple's and Google's fees remain the user's responsibility and are paid to them directly.

4. Updates

Hosting of the app and its updates are included as long as the subscription is active.

5. Content and ownership

The user remains the owner of the content they add and guarantees that they hold the necessary rights. The published app and its customers' data belong to the user.

6. Right of withdrawal

For digital content supplied immediately after purchase, the 14-day right of withdrawal may not apply if the user requested immediate performance and waived this right. The exact terms will be specified when payments open.

7. Liability

Yatsury Studio makes every effort to ensure the service runs properly, without guaranteeing that an app will be accepted by Apple or Google, who alone decide what goes on their stores.

8. Governing law

These terms are governed by French law. In the event of a dispute, an amicable solution will be sought first.
