How to Build a $10K Web App with AI (No Code Required!)

Have you ever had a game-changing idea but didn't know how to turn it into a real product?
What if I told you that you could build a fully functional web app in under 60 minutes—without writing a single line of code?

Sounds impossible, right?
I'm here to prove it's not only possible, but actually easy—thanks to three insane AI tools.

What You'll Learn

• Setting up the project using a free AI tool I built
• Building the web app using Windsurf (way easier and cheaper than Cursor!)
• Deploying the web app online with a custom domain
• Setting up payments with Stripe so you can start making money!

Step 1: Generate Your Project Blueprint (Free AI Tool!)

Starting a new project can be frustrating—one small mistake and you're stuck troubleshooting for hours.
That’s why I built BrainDumper, a free AI tool that generates a detailed project plan for you.

How to Use BrainDumper

1. Go to the first link in the description and open BrainDumper.
2. Type out every single detail of your app idea—no structure needed, just brain-dump everything.
3. Select "Web App" since we're building a web app in this guide.
4. Download the generated context file.

Once done, BrainDumper will automatically open the necessary tools for the next steps: Windsurf, Node.js, and Mobbin.

Step 2: Set Up Windsurf (Better than Cursor!)

Most AI coding tools throw code at you with no context—leaving you debugging for hours.
Windsurf is different.

Key Features

• Automatically sets up your project files and dependencies
• Keeps track of every AI-generated change
• 5 free AI prompts before requiring an upgrade

Quick Setup Steps

1. Download Windsurf
2. Open it and click Get Started
3. Choose your preferences
4. Sign up and log in
5. Install Node.js
6. Verify installation with node -v

Step 3: Design Your UI with Mobbin

Building a web app isn’t just about functionality—you need great design too.
Instead of starting from scratch, copy winning UI/UX patterns using Mobbin.

Why Use Mobbin?

• Access premium UI/UX flows from top companies
• Copy and paste high-converting designs directly
• Unlimited access to historical app designs with Pro

Quick Steps

1. Search for an app with a design you like
2. Click on a screen, then hit COPY
3. Paste the design into Windsurf
4. Let Windsurf generate the UI

Step 4: Add AI Features with DeepSeek

Now that your UI is built, let’s make it smart with AI features. We’ll use DeepSeek to create a Prompt Generator.

Setting Up DeepSeek

1. Open your .env.local file in Windsurf
2. Insert the DeepSeek API key (get it from platform.deepseek.com)
3. Test the integration using Developer Tools: press Ctrl+Shift+I → Network Tab
4. If you see a 200 Status Code, you're good to go!

Step 5: Add User Authentication with Supabase

Let’s add login and database functionality with Supabase.

How to Set Up Supabase

1. Sign up at supabase.com and create a new project
2. Copy the Anon Public Key and Project URL into Windsurf
3. Run the SQL script that Cascade provides to set up your database tables
4. Test authentication by signing up or logging in on your app

Once done, users will be able to:

• Create an account
• Log in and out
• Track their activity

Step 6: Set Up Stripe for Payments

To monetize your app, let’s add a monthly subscription using Stripe.

How to Integrate Stripe

1. Sign up at stripe.com and create a new product ($10/month)
2. Copy the Product Price ID and API Keys into your Windsurf project
3. Cascade will generate the full payment system for you
4. Users click Subscribe Now, and are redirected to Stripe’s secure checkout

Step 7: Deploy Your Web App Online

Your app is now complete—let’s deploy it to the web with Vercel.

How to Deploy on Vercel

1. Push your project to GitHub:

2. Go to vercel.com, sign in with GitHub, and click Start Deploying
3. Import your repository, name the project, and click Deploy
4. Add a custom domain under Vercel settings
