Lovable
: How to use it, features, and the business problems it solves

How to Use

1. Create an account

   Sign up on the official website (lovable.dev) with an account such as your Google account. You can start trying app-building right away on the free plan.

2. Describe what you want to build in words

   In the chat field, type something like "Build a web app that can do XYZ." You can give instructions in Japanese too, and the AI automatically generates the UI and code.

3. Adjust while viewing the preview

   The generated app is previewed on the spot. Layer on additional instructions such as "Change the button color" or "Add a login feature" to refine it.

4. Add a database and authentication

   Integrate with Supabase to add backend features such as data storage and user authentication.

5. Publish (deploy) and integrate

   Publish the app with one click; it also supports custom domain setup and code sync to GitHub.

Features

• Automatic app generation from natural language

  Generate both the screen (UI) and working code from text instructions alone. It is a flagship tool for so-called "vibe coding."

• Full-stack support

  Build not just the frontend but also backend features such as a database and authentication via Supabase integration.

• Real-time preview and interactive editing

  Complete your app by repeatedly adding and revising via chat while viewing the generated result.

• One-click deploy

  Publish your finished app instantly and set up a custom domain.

• GitHub integration

  Sync the generated code with GitHub so engineers can edit it directly.

• Team collaboration (from Lovable 2.0)

  Includes collaboration features for building apps together with multiple people, plus more advanced agent capabilities.

• Generation from images and designs

  Supports multimodal input, such as generating UI by referencing design images or screenshots.

Pricing

Pricing is current as of June 2026. Because it is denominated in US dollars, the equivalent in yen varies with exchange rates. Credit consumption varies with the complexity of your instructions. Check the official pricing page for the latest information.

• Discounts may be available for students and faculty, and discounts for nonprofits may also be offered. Annual billing is cheaper.

Pros and Cons

Pros

• Build a working web app with just chat, even without programming knowledge
• Handle everything end to end, from UI and code to backend and deployment
• Shape prototypes and MVPs in a short time, speeding up validation
• Allow full-fledged extension by engineers via GitHub integration

Cons

• The user interface (UI) is mainly in English (though the instructions themselves can be in Japanese)
• Because it is credit-based, complex development and lots of trial and error tend to drive up cost
• For large-scale or complex requirements, you may need to touch up the generated results or apply specialized knowledge

Reviews and Reputation

• Highly praised by non-engineers and for startup MVP development, who say "you just describe an idea and get a working app."
• While many say "prototyping is overwhelmingly fast," some also note that "credits get used up fast on elaborate requirements" and "in the end it helps to understand the code."
• It is often weighed against other vibe-coding tools like v0 and bolt, and a growing number of users mix and match them by use case and preference.

Frequently Asked Questions (FAQ)

Q. Can I use Lovable for free?

Yes. The free plan grants a set number of credits per day so you can try generating apps. Serious development, custom domains, and private apps require a paid plan.

Q. Can I use it in Japanese?

The user interface (UI) is mainly in English, but you can enter app-building instructions in Japanese. The finished app itself can be created in Japanese.

Q. Do I need programming knowledge?

No. You can build apps just by giving instructions via chat. That said, with GitHub integration you can edit the code directly, enabling advanced customization by engineers.

Q. Can I publish the apps I create?

Yes. You can deploy with one click, and custom domain setup is supported.
