Introduction to Vercel

Vercel is the deployment platform created by the makers of Next.js—purpose-built for frontend frameworks and serverless functions.

What is Vercel?

Vercel provides:

Vercel Platform
├── Automatic Deployments (from Git)
├── Global CDN
├── Serverless Functions
├── Edge Functions
├── Preview Deployments
├── Analytics
├── Domain Management
├── v0 Integration (AI UI generation)
└── AI SDK (for building AI apps)

Why AI Tools Use Vercel

1. Zero-Config Deployment

AI builders deploy directly to Vercel:

Lovable:

Settings → Deploy → Vercel
One click to production

Bolt.new:

Built-in Vercel integration
Auto-deploys on export

2. Next.js Optimization

Since Vercel builds Next.js, deployment is optimized:

• Server Components work automatically
• API routes become serverless functions
• Static pages are cached at edge
• Images are optimized globally

3. Git Integration

Every push triggers deployment:

git push → Build → Deploy → Live

main branch    → Production
feature branch → Preview URL

4. Environment Variables

Secure environment management:

# Production secrets
SUPABASE_SERVICE_ROLE_KEY=xxx

# Never exposed to client
DATABASE_URL=xxx

5. AI Integration

Vercel's AI ecosystem:

v0 Integration:

v0.dev → Generate UI → Deploy to Vercel
Seamless workflow from design to production

AI SDK:

// Build AI features with Vercel AI SDK
import { generateText } from 'ai'
import { openai } from '@ai-sdk/openai'

const { text } = await generateText({
  model: openai('gpt-5.4'),
  prompt: 'Write a product description...'
})

Edge AI:

Run AI inference at the edge
Low latency for global users

Core Concepts

Projects

A project is one deployed application:

Project: my-app
├── Production (main branch)
├── Preview (feature branches)
└── Deployments (history)

Deployments

Each git push creates a deployment:

Deployment: abc123
├── URL: my-app-abc123.vercel.app
├── Status: Ready
├── Created: 2 min ago
└── Source: main branch

Domains

Custom domains with automatic SSL:

myapp.com           → Production
staging.myapp.com   → Preview

Functions

Serverless functions from your code:

// app/api/hello/route.ts
// Becomes: api/hello serverless function

The Vercel Workflow

AI-Generated Apps

1. Build app with Lovable/Bolt/v0
2. Connect GitHub repository
3. Import to Vercel
4. Add environment variables
5. Deploy to production

Local Development

1. Develop locally (npm run dev)
2. Push to GitHub
3. Preview deployment created
4. Review and merge
5. Production deployed

When to Use Vercel

Good fit:

• Next.js applications
• Static sites with API routes
• AI-generated frontend apps
• Projects using Supabase backend
• Need for preview deployments

Consider alternatives when:

• Need traditional backend (use Railway)
• Need containers/Docker
• Budget constrained (use Netlify free tier)
• Need database hosting (use Supabase/Railway)

Pricing Overview

Hobby limits:

• 100GB bandwidth/month
• 100 serverless function hours
• 1 concurrent build
