Deploy Router - Vercel vs Cloudflare vs GitHub Pages Decision Engine

I intelligently route your deployment to the optimal platform based on project analysis, including repository visibility (private vs public).

When to Use This Skill

Ask me when you need help with:

• Platform Decision: "Should I deploy to Vercel or Cloudflare?"
• Project Analysis: "Analyze my project for deployment"
• SEO-Aware Routing: "I need dynamic SEO for my Next.js app"
• Cost Optimization: "What's the cheapest deployment option?"
• Edge-First: "I want global edge deployment"
• Private Repo Deployment: "Where can I deploy my private repo for free?"

🚨 CRITICAL: Repository Visibility Check (ALWAYS DO FIRST)

GitHub Pages has a major limitation: Free GitHub accounts can ONLY deploy GitHub Pages from public repositories. Private repo deployment requires GitHub Pro, Team, or Enterprise.

How to Detect Repository Visibility

# Check if git remote exists and get repo visibility
REMOTE_URL=$(git remote get-url origin 2>/dev/null)
if [[ "$REMOTE_URL" =~ github.com[:/]([^/]+)/([^/.]+) ]]; then
  OWNER="${BASH_REMATCH[1]}"
  REPO="${BASH_REMATCH[2]}"

  # Use GitHub CLI to check visibility
  VISIBILITY=$(gh repo view "$OWNER/$REPO" --json visibility -q '.visibility' 2>/dev/null)

  if [[ "$VISIBILITY" == "PRIVATE" ]]; then
    echo "⚠️  PRIVATE REPOSITORY DETECTED"
    echo "   GitHub Pages requires GitHub Pro/Team/Enterprise for private repos"
    echo "   → Recommended: Cloudflare Pages (free for private repos)"
    echo "   → Alternative: Vercel (free tier available)"
  else
    echo "✅ PUBLIC REPOSITORY - All deployment options available"
  fi

• Server Actions with complex backend logic
• Long-running API routes (> 30s execution)
• WebSocket connections (real-time features)
• Heavy image processing (Sharp, Jimp)
• PDF generation (Puppeteer, Playwright)
• Dynamic OG images with complex rendering
• getServerSideProps with database queries

Signals for CLOUDFLARE (Edge/Static):

• Static site generation (SSG)
• Simple API routes (< 30s, no Node.js deps)
• Edge-compatible database (Cloudflare D1, Turso, PlanetScale)
• KV storage for caching
• R2 for file storage
• Durable Objects for state
• Cost-sensitive deployment

Why Vercel Wins for Dynamic SEO

1. True SSR: Every request can fetch fresh data from database
2. ISR with on-demand revalidation: revalidateTag() and revalidatePath()
3. Dynamic OG images: @vercel/og generates images server-side
4. Edge + Node.js hybrid: Edge for speed, Node.js for data fetching
5. Built-in image optimization: Automatic WebP/AVIF conversion
6. Preview deployments: Test SEO before going live

When Cloudflare is SEO-Acceptable

• Static blogs: Meta tags baked at build time
• Documentation: Content rarely changes
• ISR with Workers: If 1-hour stale data is acceptable
• Hybrid approach: Cloudflare Pages + external API for dynamic data

Platform Comparison

Vercel

Best For:

• Next.js apps with full Node.js features
• Dynamic SEO (meta tags from database)
• Server Components with complex data fetching
• Image optimization (built-in)
• Preview deployments for PRs
• Teams needing easy DX

Pricing (2025):

• Hobby: Free (limited)
• Pro: $20/user/month
• Serverless Functions: 100GB-hours free, then $0.18/GB-hour
• Edge Functions: 500K free, then $0.65/million

Limitations:

• Serverless function timeout: 10s (Hobby), 60s (Pro), 300s (Enterprise)
• Edge function timeout: 30s
• Cold starts on low-traffic sites

Cloudflare

Best For:

• Static sites with edge caching
• Edge-first applications
• Cost-sensitive projects
• Simple API routes
• Global CDN distribution
• Cloudflare ecosystem (R2, D1, KV)
• 🔒 PRIVATE REPOS (works with free tier!)

Pricing (2025):

• Workers Free: 100K requests/day
• Workers Paid: $5/month + $0.50/million requests
• Pages: Unlimited sites, 500 builds/month free
• R2: 10GB free, then $0.015/GB

Limitations:

• No Node.js runtime (V8 isolates only)
• CPU time limit: 10ms (free), 30s (paid)
• Memory: 128MB
• No native modules (Sharp, Prisma binary, etc.)

Why Cloudflare for Private Repos:

• ✅ No repository visibility restrictions
• ✅ Connect private GitHub repos directly
• ✅ Automatic deployments from private branches
• ✅ Preview deployments for PRs
• ✅ Free tier is generous

GitHub Pages

Best For:

• PUBLIC repositories only (free tier)
• Open-source documentation
• Public project sites
• Static Jekyll/Hugo/Astro sites
• When source code visibility is intentional

Pricing (2025):

• Free for public repos
• Requires GitHub Pro/Team/Enterprise for private repos ($4-21/user/month)
• 1GB storage limit
• 100GB bandwidth/month

Limitations:

• ❌ NO PRIVATE REPO SUPPORT on free accounts
• No server-side rendering
• No API routes
• No dynamic content
• Build time limit: 10 minutes
• No environment variables at runtime

When to Use GitHub Pages:

✅ DO use GitHub Pages when:
   - Repository is PUBLIC
   - Content is 100% static
   - You want zero deployment config
   - Open-source project docs

❌ DO NOT use GitHub Pages when:
   - Repository is PRIVATE (use Cloudflare Pages instead!)
   - You need SSR/dynamic content
   - You need API routes
   - You need environment variables

Analysis Workflow

When user asks "where should I deploy?", I follow this order:

0. Check Repository Visibility (FIRST!)

# CRITICAL: Check if repo is private BEFORE anything else
REMOTE_URL=$(git remote get-url origin 2>/dev/null)
if [[ "$REMOTE_URL" =~ github.com[:/]([^/]+)/([^/.]+) ]]; then
  OWNER="${BASH_REMATCH[1]}"
  REPO="${BASH_REMATCH[2]}"

  # Check visibility with GitHub CLI
  VISIBILITY=$(gh repo view "$OWNER/$REPO" --json visibility -q '.visibility' 2>/dev/null)

  if [[ "$VISIBILITY" == "PRIVATE" ]]; then
    echo "🔒 PRIVATE REPO - GitHub Pages NOT available on free tier"
    echo "   Recommended: Cloudflare Pages or Vercel"
    GITHUB_PAGES_AVAILABLE=false
  else
    echo "✅ PUBLIC REPO - All platforms available"
    GITHUB_PAGES_AVAILABLE=true
  fi
else
  echo "⚠️  No GitHub remote detected - assuming private"
  GITHUB_PAGES_AVAILABLE=false
fi

1. Scan Project Structure

# Framework detection
ls -la | grep -E "next.config|remix.config|astro.config|nuxt.config|svelte.config|vite.config"

# Package.json analysis
cat package.json | jq '.dependencies, .devDependencies'

# Check for SSR/SSG configuration
grep -r "getServerSideProps\|getStaticProps\|generateStaticParams" --include="*.tsx" --include="*.ts" | head -20

2. Detect Node.js Dependencies

# Native module detection
grep -E "prisma|sharp|puppeteer|playwright|canvas|bcrypt|argon2" package.json

# File system usage
grep -r "require\('fs'\)\|from 'fs'\|import fs" --include="*.ts" --include="*.tsx" --include="*.js" | head -10

# Crypto usage
grep -r "require\('crypto'\)\|from 'crypto'" --include="*.ts" --include="*.tsx" | head -10

3. Analyze SEO Requirements

# Dynamic meta detection
grep -r "generateMetadata\|Head.*title\|meta.*content" --include="*.tsx" --include="*.ts" | head -10

# Database calls in metadata
grep -rB5 "generateMetadata" --include="*.tsx" | grep -E "prisma|db\.|fetch\("

# Check for e-commerce/content patterns that need fresh SEO
grep -rE "product|price|inventory|article|news" --include="*.tsx" | head -10

4. Generate Recommendation

Based on analysis, I provide:

## 🚀 Deployment Recommendation

**Platform**: [VERCEL / CLOUDFLARE]
**Confidence**: [HIGH / MEDIUM / LOW]

### Analysis Results

Integration with DevOps Agent

After recommendation, I trigger the appropriate deployment:

// For Vercel deployment
Task({
  subagent_type: "sw-infra:devops:devops",
  prompt: `Deploy to Vercel:
    - Project: ${projectName}
    - Framework: ${framework}
    - Environment: ${env}
    Use existing VERCEL_TOKEN from .env`,
  description: "Deploy to Vercel"
});

// For Cloudflare deployment
Task({
  subagent_type: "sw-infra:devops:devops",
  prompt: `Deploy to Cloudflare:
    - Project: ${projectName}
    - Type: ${isStatic ? 'Pages' : 'Workers'}
    Use wrangler CLI (already authenticated)`,
  description: "Deploy to Cloudflare"
});

- Framework: Next.js 14
- Database: Prisma (requires Node.js runtime)
- Impact: MUST use Node.js-compatible host

Recommendation: VERCEL
- Prisma requires Node.js runtime (binary execution)
- Cloudflare Workers don't support Prisma's native binary
- Vercel provides Node.js serverless functions

Alternative: Use Prisma Edge with Cloudflare D1 (requires migration)

Example 2: Astro Blog

User: "Best deployment for my Astro blog?"

Analysis:
- Framework: Astro (static-first)
- Database: None
- SEO: Static meta tags only

Recommendation: CLOUDFLARE PAGES
- 100% static site, no server runtime needed
- Free tier covers most blogs
- Global edge CDN included
- Faster than Vercel for static content

Example 3: Next.js E-commerce with Dynamic SEO

User: "I'm building an e-commerce site with product pages that need dynamic meta tags from the database"

Analysis:
- Framework: Next.js
- SEO: Dynamic meta from database (products, prices)
- Database: PostgreSQL with product catalog

Recommendation: VERCEL
- Dynamic `generateMetadata()` with DB calls
- Server-side rendering for SEO
- Product pages need fresh data for Google
- Cloudflare would require ISR which may show stale prices

Example 4: Private Repo Static Site (🔒 IMPORTANT!)

User: "Where should I deploy my private Astro documentation site?"

Analysis:
- Framework: Astro (static-first)
- Repository: PRIVATE ⚠️
- SEO: Static meta tags only
- Content: Internal documentation

Step 0 - Visibility Check:
🔒 PRIVATE REPO DETECTED
❌ GitHub Pages: NOT AVAILABLE (requires GitHub Pro/Team)
✅ Cloudflare Pages: Available (free tier)
✅ Vercel: Available (free tier)

Recommendation: CLOUDFLARE PAGES
- Private repo works with free tier
- Static site = perfect fit for edge deployment
- Fast global CDN
- 500 builds/month free
- No Node.js needed

Alternative: Vercel (also works, but Cloudflare is cheaper for static)

⚠️ DO NOT recommend GitHub Pages for private repos!

Example 5: High-SEO E-commerce (Vercel wins)

User: "I need the best SEO possible for my product catalog with 10,000+ products"

Analysis:
- Framework: Next.js 14 with App Router
- Products: 10,000+ items with prices, inventory, reviews
- SEO Requirements: CRITICAL
  - Dynamic meta tags per product
  - Real-time pricing in structured data
  - Fresh inventory status for Google
  - Dynamic OG images showing product photos

SEO Analysis Results:
| Requirement | Vercel | Cloudflare | GitHub Pages |
|-------------|--------|------------|--------------|
| Dynamic meta from DB | ✅ SSR | ⚠️ ISR (stale) | ❌ |
| Real-time prices | ✅ | ⚠️ (1hr delay) | ❌ |
| Dynamic OG images | ✅ @vercel/og | ⚠️ Limited | ❌ |
| Inventory freshness | ✅ SSR | ⚠️ Cache | ❌ |

Recommendation: VERCEL (STRONG)
- SSR ensures Google sees fresh data every crawl
- `generateMetadata()` with database calls
- `@vercel/og` for product OG images
- ISR with on-demand revalidation for cache-then-fresh
- Image optimization built-in

Why NOT Cloudflare:
- ISR cache means Google might see stale prices
- No native OG image generation
- Edge runtime can't run Prisma directly

Cost consideration:
- Vercel Pro ($20/month) vs Cloudflare (free)
- For critical SEO sites, Vercel Pro is worth it

Migration Paths

Vercel → Cloudflare

1. Replace Prisma with Drizzle + D1/Turso
2. Convert Server Components to Edge-compatible
3. Use @cloudflare/next-on-pages adapter
4. Move file storage to R2

Cloudflare → Vercel

1. Remove Cloudflare-specific bindings (KV, D1, R2)
2. Replace with Vercel equivalents (Edge Config, Postgres, Blob)
3. Update wrangler.toml to vercel.json
4. Test Node.js compatibility

Framework-Specific Guidance

Remix (Special Case)

Remix is uniquely positioned to work well on BOTH platforms:

Remix + Cloudflare Decision:

If your Remix app:
├─ Uses only edge-compatible packages → Cloudflare ✅
├─ Needs KV/D1/R2 storage → Cloudflare ✅ (native support)
├─ Is cost-sensitive → Cloudflare ✅ (cheaper)
├─ Needs Prisma/native modules → Vercel (Node.js required)
├─ Has critical dynamic SEO → Vercel (SSR power)
└─ Needs WebSockets → Vercel (Durable Objects are complex)

Remix Setup for Cloudflare:

npx create-remix@latest --template cloudflare-pages

Remix Setup for Vercel:

npx create-remix@latest --template vercel

Backend Services (Cron Jobs, Workers)

Cost Optimization Tips

1. Start on Cloudflare if you're unsure - it's free and generous
2. Migrate to Vercel only when you hit Node.js requirements
3. Use Vercel Edge when possible (cheaper than Serverless)
4. Cache aggressively on Cloudflare (KV, R2, Workers KV)
5. Use ISR with long revalidation periods when real-time isn't critical
6. Monitor usage - set billing alerts on both platforms
7. Consider Railway for backend services (cheaper than Vercel for workers)
