How to Build a Simple Web App Using Cursor AI in Under 2 Hours

If you're like me, you want to ship projects quickly. The idea of spending weeks coding a web app can be daunting, especially if you're a solo founder or indie hacker. But what if I told you that you could build a simple web app using Cursor AI in under 2 hours? In 2026, tools like Cursor AI are making it easier than ever to leverage artificial intelligence for coding without needing to be a programming expert.

Prerequisites: What You Need to Get Started

Before diving into the build, make sure you have:

• Cursor AI account: Free tier available, but you might want the pro version for advanced features ($20/month).
• Basic understanding of web app concepts: You should know what a web app is and have a rough idea of how to navigate a coding environment.
• Code editor: I recommend using Visual Studio Code, which is free and widely used.

Step 1: Set Up Your Environment

1. Create a New Project: Open Cursor AI and create a new project. Use the template for a basic web app.
2. Choose Your Stack: For this tutorial, we’ll use HTML, CSS, and JavaScript. Cursor AI can help generate the boilerplate code for you.
3. Define Your App's Purpose: Decide on what your simple web app will do. For this example, let’s create a simple to-do list app.

Step 2: Building the To-Do List App

Using Cursor AI, follow these steps:

1. Generate HTML Structure:

   • Ask Cursor AI to create a basic HTML structure for a to-do list app. It should include an input field, a button, and a list to display tasks.
   • Example command: "Generate HTML for a to-do list app."

2. Add CSS for Styling:

   • Request Cursor AI to generate CSS to style your app. Keep it simple with a clean layout.
   • Example command: "Generate CSS for a minimalistic to-do list."

3. Implement JavaScript Functionality:

   • Now, ask Cursor AI to provide JavaScript code that allows users to add tasks and mark them as complete.
   • Example command: "Generate JavaScript for adding tasks to a to-do list."

Expected Outputs:

• A functional to-do list with the ability to add and remove tasks.
• A clean and user-friendly interface styled with CSS.

Step 3: Testing Your App

Once your app is built, it's time to test it:

1. Open your HTML file in a web browser.
2. Check that you can add tasks and that they display correctly.
3. Make sure the tasks can be marked as complete and removed.

Troubleshooting Common Issues:

• Tasks not displaying: Check your JavaScript console for errors. Often, a small typo can cause issues.
• Styling not applying: Ensure your CSS file is linked correctly in the HTML.

What's Next: Deploying Your Web App

Now that you have a working web app, consider deploying it. Here are some options:

• GitHub Pages: Free and easy to set up. Great for static sites.
• Netlify: Also free for basic usage, with additional features for scaling.
• Vercel: Good for serverless functions and easy deployments.

Conclusion: Start Here

Building a simple web app using Cursor AI can be done in under 2 hours, even if you’re not a coding expert. The key is to leverage AI tools to speed up the process. If you’re ready to ship your own project, start by signing up for Cursor AI and following the steps outlined above.

What We Actually Use

In our experience, we rely on Cursor AI for rapid prototyping and coding assistance. While it’s not a complete replacement for understanding coding fundamentals, it significantly reduces the time spent on boilerplate code and allows us to focus on the unique aspects of our projects.
