### What is Euthopia?
Eureka Labo, Inc. (CEO: Yujiro Higawa) will officially release "Euthopia," a platform that generates and publishes full-stack web applications simply by conversing with AI, on April 1, 2026.
In recent years, overseas AI app builders such as Lovable, Bolt, Replit, and v0 have rapidly evolved, with some tools even supporting databases, authentication, payments, and hosting. However, **there is currently no Japan-born AI app builder.** There is no Japanese-optimized option that feels natural for Japanese users and developers—Euthopia was born to fill this void.
Euthopia provides **all built-in** features: database, user authentication, Stripe payments, and production hosting. By simply describing the app you want to create in Japanese, a **production product** can be completed in minutes. You can publish it as is, have users sign up, and receive payments.
Euthopia particularly focuses on **AI output accuracy**. Not just a beautiful appearance, but ensuring that the generated code functions without errors. We have thoroughly crafted the prompt design and code extraction logic to pursue the experience of "generate and it just works."
You can start for free, no credit card registration is required. 5 credits are given daily, allowing access to all features.
### Main Features
**Everything you need for your product is included from the start.**
- **Database** — Table definitions and CRUD APIs are automatically generated. Manual schema design is unnecessary. If a user says, "Add a product management function," a product table and its API will be automatically constructed.
- **User Authentication** — Email/password authentication is integrated with one click. User registration, login, and session management are automatically built, eliminating the need to write a single line of authentication-related code.
- **Stripe Payments** — Supports both checkout (one-time payments) and subscriptions (recurring billing). This allows you to create monetizable products without complex Stripe API integration work.
- **Production Hosting** — Instantly issues a live URL for the generated app. No server setup, domain configuration, or deployment settings are required. Just press the "Publish" button, and you get a URL accessible from anywhere in the world.
- **Iterative Improvement through Conversation** — Simply by stating, "Add dark mode," "Add a product review function," or "Simplify the payment flow," the AI instantly updates the app. There's no need to aim for perfection from the start; it's a new development experience where you refine through dialogue.
Supported frameworks include HTML + Tailwind CSS (for LPs, portfolios, blogs).
