How to Deploy Your First Web App: Complete Beginner Guide

You've finally built something cool — maybe a React portfolio, a Next.js blog, a todo app, or even a simple static site with HTML, CSS, and JavaScript.
Now comes the most exciting part: making it live so anyone in the world can visit it.

In this complete beginner guide, I'll walk you through exactly how to deploy your first web app for free, step by step — no prior experience needed.

New to web development? Start with our HTML, CSS, and JavaScript roadmap or Want to Start a Career as a Web Developer.

Why Deploying Your First App Is a Game-Changer

  • Show your work in job applications and portfolios
  • Get real feedback from actual users
  • Learn production workflows early
  • Enjoy free global hosting, automatic HTTPS, and scaling

Best part? You can do all of this completely for free with modern platforms.

Step-by-Step: Deploy Your First Web App (Free)

Phase 1: Prepare Your Project (30–60 Minutes)

  1. Push your code to GitHub (free forever)

1git init 2git add . 3git commit -m "Initial commit" 4git remote add origin https://github.com/yourusername/your-repo-name.git 5git branch -M main 6git push -u origin main 7 8

  • Test production build locally

    • React / Vite: npm run build → npm run preview
    • Next.js: npm run build → npm run start

  • Add .env variables (if your app uses API keys or database URLs) → Never commit .env files (add to .gitignore)

  • Clean up

    • Remove console.log()
    • Check mobile responsiveness
    • Fix any obvious bugs

    • If your app needs a database, check our Database Roadmap for Web Developers.

    Phase 2: Choose the Best Free Deployment Platform

    Platform Best For Free Tier Limits Ease of Use
    Vercel Next.js, React, full-stack apps Unlimited sites, generous bandwidth ★★★★★
    Netlify Static sites, Jamstack, forms 100 GB bandwidth / month ★★★★★
    GitHub Pages Pure static HTML/CSS/JS sites Unlimited for public repos ★★★★☆
    Cloudflare Pages Static + Workers (functions) Unlimited sites ★★★★☆
    Render Full-stack (Node.js + database) Free tier with limits ★★★★☆

    Recommendation for most beginners:

    • Using Next.js or React → Vercel (easiest & fastest)
    • Static site only → Netlify or GitHub Pages

    Phase 3: Deploy in Under 5 Minutes (Vercel Example)

    1. Go to → https://vercel.com
    2. Sign up (GitHub login is fastest)
    3. Click New Project → Import Git Repository
    4. Select your GitHub repo
    5. Vercel auto-detects framework (Next.js, React, etc.)
    6. Add environment variables (if any) in the dashboard
    7. Click Deploy

    → Done!

    Your app is live at: https://your-app-name.vercel.app

    Netlify works almost the same way: → https://netlify.com → New site from Git → connect GitHub → deploy.

    Every time you push to GitHub → your app automatically updates!

    Phase 4: Make It Professional

    • Custom domain (optional but looks pro)
      • Buy from Namecheap (~$10–12/year) → add DNS records in Vercel/Netlify
    • HTTPS → Automatic on all platforms
    • Analytics → Add Google Analytics or use built-in dashboard
    • Custom 404 page → Nice touch for users

    Project idea: Deploy the todo app or blog from our Frontend vs Backend Development guide.

    Phase 5: Common Beginner Mistakes to Avoid

    • Committing .env files (huge security risk)
    • Not testing production build locally
    • Ignoring bandwidth limits on free tiers
    • Forgetting to add .gitignore for node_modules
