Vibe code using Lovable AI and Logto to quickly build your app and handle login flows

From general-purpose agents to task-specific copilots, developers are witnessing a fundamental shift in how software is created. But among all agent categories, one stands out as the most exciting and fast-moving: coding agents.

Tools like Lovable, Cursor, Windsurf and Replit are making headlines by turning natural language into real, working software instantly. No setup. No boilerplate. Just pure output.

Today, a new term enters the scene: Vibe Coding.

Pioneered by Lovable, vibe coding is a new way to build apps by chatting with AI. In this article, we’ll unpack what vibe coding really means, explore how Lovable works as one of the leading coding agents, and walk through building a full-stack app: complete with sign-up, login, user and identity management in minutes.

What is Lovable AI?#

Lovable is a chat-based development platform where your ideas turn directly into working code, layouts, and even hosted apps. You don’t write traditional code : you describe what you want:

“I need a simple dashboard with two charts and a sidebar.”

And the AI generates a live preview and editable source code, often in seconds.

Under the hood, Lovable uses modern frameworks like React and Tailwind, and it lets you export your project, self-host, or deploy instantly.

What are the core features of Lovable AI#

Here’s a detailed table based on the 9 key features of the Lovable platform:

Key benefits of using Lovable for app development#

Lovable challenges some of the assumptions baked into most developer workflows:

• That you need a blank VS Code window to start.
• That you need Figma mockups before layout.
• That you need tickets before logic.

Instead, Lovable offers a working environment where natural language becomes the primary UX not just for coding, but for building entire products.

This has huge implications for:

• Prototyping: No more static mockups: test real UX ideas in hours.
• Onboarding: New team members can explore code and features conversationally.
• Accessibility: Designers and PMs can contribute without needing to write code.

For those without a professional software development background, Lovable unlocks a new level of creative freedom. As long as you know what you want to build, you can vibe code your way through it — turning ideas into working apps without hitting the usual blockers.

What we can learn from Lovable#

The interface is the new IDE#

Lovable is showing that “coding” doesn’t always mean typing. It can mean prompting, editing through dialogue, and iterating through intent.

This opens up opportunities for more inclusive collaboration, especially in small teams or solo projects.

Fast loops beat full specs#

When you can build, test, and refine without switching tools or writing boilerplate, you unlock faster iteration and more space for creativity.

Even experienced developers benefit from the reduced context-switching and faster feedback loops.

AI-native apps need AI-native tooling#

Just like GitHub Copilot made sense inside VS Code, Lovable makes sense for the emerging generation of agent-driven, prompt-native apps — where structure, logic, and user flows are no longer hardcoded but dynamically defined.

Build a photo gallery app using Logto as authentication#

First, just give it a simple prompt like “Create a photo gallery app”, it will generate a basic but nicely designed website for you.

Integrate Logto Auth in Lovable#

Then I asked Lovable to use Logto for authentication. While Lovable seems to have a strong partnership with Supabase for auth, Supabase isn’t a professional CIAM solution. In this case, I chose Logto — an open-source and professional CIAM product.

According to the instructions, I needed to provide:

1. Logto endpoint
2. App ID

Since it’s a React single-page app, no app secret is required. The AI handled everything smoothly — it automatically installed the latest Logto React SDK and created the necessary authentication components.

To get the endpoints, I simply went to Logto Cloud and created a new React app. On the application details page, I found the necessary endpoints and copied them into Lovable. Lovable then automatically updated the code and config files for me.

You’ll also need to enter your app’s Redirect URI and Post-Sign-out URL.

Here’s the tricky part: since Lovable hosts your development environment in the cloud, you can’t use something like http://localhost:3000/callback for the redirect URI. Instead, you need to use your Lovable project’s live URL and update it in the Logto Cloud console.

Steps:

1. Go to your Logto Cloud tenant
2. Find your app
3. Replace the URLs with:

• Redirect URIs:

  https://preview--snap-show-gallery-time.lovable.app/callback

• Post Sign-out Redirect URIs:

  https://preview--snap-show-gallery-time.lovable.app/

After a few chat prompts and iterations, you now have a protected website—only signed-in users can view the content.

Please note, since this kind of coding agent have iframes in its preview mode so when you click in the preview mode it can’t trigger the the sign-in page.

Test the sign-in flow#

After you click “Sign in,” it will open the Logto login page. You can test the full authentication flow — by default, Logto uses email + password as the sign-in method. Just go through the email verification process, and then check in the Logto Console to see if the user was successfully registered.

As you can see, your user now appears in the Logto Cloud console — this confirms that the authentication flow worked, and the user was securely registered through your app.

Now you have a fully working app with integrated login flows — and you can also manage your users directly through the Logto Cloud console.

Logto’s upcoming update will support AI-powered auth integration#

This is just a simple example. Logto is actively developing MCP servers that run right inside your IDE, making it possible to interact with the Logto Console and Management API—all without leaving your development environment. With this setup, you’ll be able to:

1. Create and manage users
2. Access logs
3. Configure and manage login flows
4. Design and maintain authorization (e.g. API resources, permissions, roles)
5. Manage applications and resources
6. And much more

With the combined power of AI and Logto’s solid infrastructure, integrating auth is no longer a complex task.
