How to Code a Simple Web App Using AI Tools in Just 2 Hours

Building a web app can feel daunting, especially if you're not a seasoned developer. But what if I told you that with the right AI tools, you could whip up a simple web app in just 2 hours? In 2026, AI tools have become more accessible than ever, making it possible for indie hackers and solo founders to create functional applications without extensive coding skills.

Prerequisites: What You Need Before You Start

Before diving in, make sure you have the following:

• A computer with an internet connection.
• Basic understanding of HTML/CSS: This will help you customize your app more easily.
• Accounts on the following AI tools:
  • OpenAI (for code generation)
  • Vercel or Netlify (for deployment)
  • Airtable (for database management)

Expected Output

By the end of this tutorial, you’ll have a simple web app that can take user input and display results based on that input.

Step 1: Define Your Web App's Purpose

First, decide what your web app will do. For this tutorial, let’s create a simple “To-Do List” app. This app will allow users to add tasks, mark them as complete, and delete them.

Step 2: Generate Basic Code with AI

Using OpenAI Codex

1. Access OpenAI Codex: Go to the OpenAI website and log in.
2. Prompt the AI: Type in a prompt like “Generate a simple To-Do List web app using HTML, CSS, and JavaScript.”
3. Review and Modify: The AI will provide you with code. Review and make any necessary tweaks to fit your needs.

Example Code Snippet

<!DOCTYPE html>
<html>
<head>
    <title>To-Do List</title>
</head>
<body>
    <h1>My To-Do List</h1>
    <input type="text" id="taskInput" placeholder="Add a new task...">
    <button onclick="addTask()">Add</button>
    <ul id="taskList"></ul>

    <script>
        function addTask() {
            // Your code here
        }
    </script>
</body>
</html>

Step 3: Customize Your App

Use the code generated by OpenAI to customize your app. You can add styles using CSS, such as changing colors or fonts to improve the user interface.

Simple CSS Example

body {
    font-family: Arial, sans-serif;
}
button {
    background-color: #4CAF50;
    color: white;
}

Step 4: Set Up Database with Airtable

1. Create an Airtable Account: Sign up and create a new base for your tasks.
2. Set Up Fields: You’ll need fields for task names and completion status.
3. Connect Your App: Use Airtable’s API to connect your web app to your database.

Step 5: Deploy Your App

Using Vercel or Netlify

1. Create an Account: Sign up for either Vercel or Netlify.
2. Deploy Your Code: Upload your HTML file and any associated assets.
3. Get Your Link: Once deployed, you’ll receive a live link to your web app.

Troubleshooting: What Could Go Wrong?

• API Errors: If your app doesn’t connect to Airtable, double-check your API key and base URL.
• Deployment Issues: Ensure that your file structure is correct when deploying.

What's Next

After building your To-Do List app, consider expanding its functionality. You might add user authentication, integrate a calendar, or even enable sharing tasks with friends.
