5 Steps to Your Kid's First AI-Built Web App

"I think my kid should learn to code, but I have no idea where to start." This is the question we hear most from parents. This post walks through the 5-step process for a child to build their first web app and deploy it to the real internet, using AI tools like Claude Code. Total time: 60 to 90 minutes.

"Traditional coding education focuses on syntax memorization. AI coding lets kids implement their ideas immediately — the engagement is a completely different level." — Evan Park, SpyBuilders founder

01. Setup — Done in 10 Minutes

Install Claude Code and create your child's learning account. Average time: 10 minutes.

• Mac or Windows computer required
• One command to install the Claude Code CLI
• Parent email verification

02. Mission Selection — Matched to Your Kid's Level

Pick a SPY mission matched to the child's level. Beginner missions include "My Introduction Page", intermediate includes a "Quiz App", advanced is "Family Schedule Sharing" — all actually useful projects, not toy examples.

03. Coding with AI — Just Describe What You Want

Give Claude Code instructions in plain language. If a kid says "make a page with a blue background and my name in big letters", the AI writes the actual HTML/CSS.

$ claude "build a page with my name in big letters"

✓ Created index.html
✓ Created style.css
🎉 Open it in your browser!

04. Test & Iterate — See It, Say It, Fix It

Open the app, try it out, and tell the AI what to change. Something like "make the background yellow" is all it takes.

05. Deploy & Share — A Real URL to Show Friends

One command deploys the app to Vercel. The moment a child shares a real URL with friends and family is the most emotional moment in the entire SpyBuilders journey.

Next Steps

Once your child has built a first app, they can move on to the intermediate curriculum (React + API integration). See real kid-built projects on the blog index.
