Bolt.new Tutorial: Building a SaaS in 10 Minutes with Pure Vibes

If Cursor is the tool for professional developers, Bolt.new (by StackBlitz) is the tool for dreamers.

It is a browser-based development environment that allows you to prompt an entire full-stack application into existence. It handles the frontend, the backend, the database, and the deployment—all in a single tab.

In this tutorial, we will build a “Micro-SaaS”: A subscription-based AI Image Generator. And we will do it without writing a single line of code manually.

What is Bolt.new?

Bolt.new is an AI-powered sandbox. Unlike ChatGPT, which gives you code snippets to copy-paste, Bolt.new runs the code. It has a built-in terminal, a file system, and a preview window. It is essentially a “Vibe Coding” machine.

Step 1: The “God Prompt”

Go to bolt.new. You will see a simple chat box. This is where the magic happens.

The Prompt:
> “Build a modern, dark-mode SaaS application called ‘DreamPix'. It should allow users to generate images using an AI API. It needs a landing page with a pricing table (Free, Pro, Enterprise), a login page, and a dashboard where they can see their generated images. Use React, Tailwind CSS, and Lucide icons.”

Step 2: Watch the Magic

Bolt.new will start “thinking.” It will:
1. Plan: Create a file structure.
2. Install: Run `npm install` for dependencies.
3. Code: Write the `App.tsx`, `Sidebar.tsx`, `Pricing.tsx`, etc.
4. Launch: Start the dev server.

Within 60 seconds, you will see a live preview of your app on the right side of the screen.

Step 3: Iterating with Vibes

The first version is never perfect. Maybe the colors are off. Maybe the button doesn't work.
* Prompt: “Make the ‘Generate' button a gradient purple.”
* Prompt: “Add a ‘Download' icon to the image cards.”
* Prompt: “The pricing table looks cramped. Add more padding.”

Bolt.new updates the preview instantly. This is the definition of Flow State.

Step 4: Adding Logic (The Hard Part)

Now, let's make it work.
* Prompt: “Connect the ‘Generate' button to a mock API that returns a random placeholder image after 2 seconds of loading state.”

Bolt.new will write the `fetch` logic, handle the `isLoading` state, and update the UI.

Step 5: Deployment

This is the best part. Click the “Deploy” button in the top right.
Bolt.new will deploy your app to Netlify or Vercel instantly. You get a live URL (e.g., `dreampix-alpha.netlify.app`) that you can share with the world.

Conclusion

Bolt.new represents the democratization of software creation. You don't need a powerful laptop. You don't need to know how to configure Webpack. You just need an idea and the ability to describe it.

At BYS Marketing, we use tools like Bolt.new to build “Throwaway Prototypes” for our clients. We can show you a working version of your idea in the first meeting, not the fifth.
