This guide will walk you through creating and deploying your first app with itsalive.co. You'll set up your project, build something with Claude, and have it live on the internet in minutes.
Prerequisites
You'll need:
- Node.js installed (for running npx)
- Claude Code or another AI coding assistant
- An email address for verification
Step 1: Create Your Project
Create a new folder for your app:
mkdir my-app
cd my-app
Step 2: Initialize with itsalive
Run the itsalive CLI to claim your subdomain and set up deployment:
npx itsalive-co
You'll be prompted for:
- Subdomain: Pick a unique name (e.g., "my-awesome-app")
- Email: Your email for verification
Check your inbox and click the verification link. The CLI will detect this and create a starter index.html file for you.
Step 3: Build with Claude
Now open Claude Code in your project folder and start building:
claude
Tell Claude what you want to build. For example:
- "Build me a personal portfolio site with my projects"
- "Create a todo app that saves tasks to the database"
- "Make a simple blog where I can post updates"
Claude will create the HTML, CSS, and JavaScript files for your app. It already knows about itsalive.co's APIs for auth, database, and more.
Step 4: Deploy Your Changes
After Claude builds your app, deploy it:
npx itsalive-co
Your files will be uploaded and you'll see your live URL:
✨ https://my-awesome-app.itsalive.co
Step 5: Iterate
Keep vibing! Make changes with Claude, then run npx itsalive-co to deploy. The cycle is:
- Tell Claude what to build or change
- Run
npx itsalive-coto deploy - Check your live site
- Repeat
