Summary  
This chapter explains how to verify a live deployment is working correctly and how to use version control commands to push updates that automatically trigger redeployments.

General domain of usage  
Web application deployment

Your app is deployed. This chapter covers two things: confirming everything works on the live URL, and knowing how to push future changes to the web.

### Testing your live app

When Vercel finishes deploying it gives you a URL that looks something like your-project-name.vercel.app. Open it in your browser and test the app the same way you did locally. Try the full flow end to end:

- Type an idea into the input field;
- Use any features you added like the enhance button;
- Submit and wait for the AI response to come back.

If the AI response loads correctly your environment variable was set up properly and your app is fully working on the web.

If the page loads but the AI response fails, go back into your Vercel project settings, check your environment variables, and make sure the key and value were entered correctly.

Note

### Sharing your app

That Vercel URL is your live app. You can send it to anyone and they can open it in their browser without needing to be on your computer or network. This is your MVP, live on the internet.

You can also add a custom domain in Vercel if you want a more professional URL. That is optional.

### Pushing future changes

Every time you make a change in Claude Code and want it to appear on the live web app, you need to push those changes to GitHub. Vercel watches your GitHub repository and automatically redeploys whenever new code arrives.

The three commands that make this happen are:

```
git add
git commit
git push
```

You do not need to run these yourself. Just ask Claude Code:

```"Push my latest changes to GitHub."```

Claude Code will run all three commands for you. Once it does, Vercel picks up the update and redeploys automatically within a minute or two.

### The update loop

This is the full cycle from this point forward. Every improvement you make follows the same three steps.

```
Make a change in Claude Code → Push to GitHub → Vercel redeploys automatically
```

What is the best way to confirm your app works after deploying it online?

Build and launch a real app in just one weekend using modern AI tools and a simple, practical workflow, using Claude Code to plan, generate, and refine your code, managing your project with GitHub, and deploying your finished app online with Vercel. You’ll start with an idea and quickly turn it into a clear project plan, then move step by step into building a working application, focusing on core features, simple architecture, and fast iteration instead of unnecessary complexity, while learning how to work effectively with AI by writing better prompts, fixing errors, and improving features, ending with a live app, a clean GitHub project, and a repeatable system for turning future ideas into real products faster.

Understand the basics of AI-assisted development, set up your environment, and get familiar with Claude Code before starting your first app.

Turn your idea into a clear, simple plan and define the smallest version of your app that delivers real value.

Go from zero to a running app by generating code with AI, setting up the project, and understanding what was created.

Improve your app by adding features, refining the design, and learning how to fix issues effectively.

Publish your project, make it accessible online, and ensure everything works using GitHub and Vercel.
