How to Build a Simple Web App Using AI Coding Tools in 72 Hours

Have you ever felt overwhelmed by the prospect of building a web app? You’re not alone. Many indie hackers and solo founders face this daunting task, often delaying their ideas because they don't have a technical background. But what if I told you that you could build a functional web app in just 72 hours using AI coding tools? In this guide, I’ll walk you through the process, share the tools we used, and provide honest insights on what works and what doesn’t.

Time Estimate: 72 Hours

Yes, you can finish this project in 72 hours if you use the right tools and follow a structured approach.

Prerequisites

Before diving in, make sure you have:

• A basic understanding of web technologies (HTML, CSS, JavaScript)
• An account with the AI coding tools listed below
• A clear idea for your web app (even a rough idea will do!)

Step-by-Step Guide to Building Your Web App

1. Define Your Web App Idea

Start by outlining what your web app will do. Keep it simple. A good rule of thumb is to focus on solving one specific problem. For example, if you're building a task manager, identify the core features such as adding tasks, marking them complete, and categorizing them.

2. Choose Your AI Coding Tools

Here’s a breakdown of the tools you’ll need, along with their pricing and features:

| Tool Name | What It Does | Pricing | Best For | Limitations | Our Take | |--------------------|--------------------------------------------------|-----------------------------|----------------------------------|--------------------------------------|-------------------------------| | GitHub Copilot | AI-powered code suggestions in your IDE | $10/mo | Developers needing quick code | Limited to supported IDEs | We use this for quick fixes. | | Replit | Online IDE with collaborative features | Free tier + $20/mo pro | Beginners looking for an easy setup | Performance can lag with larger projects | Great for prototyping. | | ChatGPT | AI chatbot for coding help and explanations | Free tier + $20/mo pro | Getting coding advice and examples | May provide outdated or incorrect info | We use it for brainstorming. | | Bubble | No-code platform for building web apps | Free tier + $29/mo pro | Non-coders wanting to build quickly | Limited customization for complex apps | We don't use it because we prefer code. | | Vercel | Hosting platform for frontend apps | Free tier + $20/mo pro | Deploying frontend applications | Limited backend capabilities | We use it for hosting our projects. | | Firebase | Backend as a service with real-time database | Free tier + $25/mo for advanced features | Building scalable apps | Can get complicated with scaling | We use it for user authentication. | | Figma | Design tool for UI/UX mockups | Free tier + $12/mo pro | Creating app designs | Not a coding tool | We use it for design mockups. | | Postman | API testing and development tool | Free tier + $12/mo pro | Working with APIs | Can be overwhelming for beginners | Useful for API testing. | | Airtable | Flexible database tool | Free tier + $10/mo pro | Organizing app data | Limited to 1,200 records on free tier | We use it for data management. | | Notion | Documentation and project management | Free tier + $8/mo pro | Keeping track of project details | Not a coding tool | We use it for documentation. |

3. Set Up Your Development Environment

Using Replit, create a new project and integrate GitHub Copilot for code suggestions. This will save you time and help you avoid common pitfalls.

4. Build the Frontend

Use HTML and CSS to create your app’s interface. If you're stuck, ChatGPT can help you with specific coding questions. For design, Figma will allow you to visualize your app before coding it.

5. Develop the Backend

For the backend, Firebase is a robust option that allows you to set up authentication and a real-time database quickly. Follow their documentation to get started, and use Postman to test your API endpoints.

6. Deploy Your App

Once you've built your app, use Vercel to deploy it. It integrates seamlessly with GitHub, so you can deploy directly from your repository.

7. Test and Iterate

After deployment, gather feedback from users and make necessary adjustments. Focusing on user experience will ensure your app meets their needs.

Troubleshooting Common Issues

• Deployment Errors: Check your environment variables and ensure they are correctly set.
• API Issues: Use Postman to test each endpoint in isolation.
• Design Discrepancies: Revisit Figma to ensure your designs match your implementation.

What’s Next?

After you’ve launched your web app, consider adding features based on user feedback. You can also explore marketing strategies to attract more users, like content marketing or social media campaigns.

Conclusion: Start Here

If you’re ready to build your first web app, start by defining your idea and choosing the right AI coding tools from the list above. You’ll be surprised at how quickly you can go from concept to launch.

What We Actually Use

In our experience, we primarily use GitHub Copilot for coding, Replit for prototyping, Firebase for backend services, and Vercel for deployment. These tools have proven reliable and cost-effective for indie projects.
