Cloudflare and AWS CloudFront are the two most widely used CDN and edge platforms in the world. Cloudflare operates over 300 Points of Presence (PoPs) globally and handles roughly 20% of all internet traffic. CloudFront is deeply integrated into the AWS ecosystem with over 600 edge locations. The choice between them comes down to: are you already on AWS, and how much do you value pricing simplicity?
Quick Verdict
Choose CloudFront if you're already on AWS and need tight integration with S3, EC2, API Gateway, Lambda@Edge, and prefer a single AWS bill.
Feature Comparison
| Feature | Cloudflare | AWS CloudFront |
|---|---|---|
| PoP Count | 300+ | 600+ edge locations |
| Free Tier | Unlimited bandwidth ✓ | 1TB/month for 12 months only |
| Pricing (data transfer) | Free plan / $20/mo Pro | $0.0085–$0.12/GB (region-dependent) |
| DDoS Protection | Unmetered, always-on, best-in-class | AWS Shield Standard (free) / Advanced ($3,000/mo) |
| Edge Compute | Workers (V8 isolates, fast cold start) | Lambda@Edge (Node.js/Python, slower cold start) |
| WAF | ✓ (free OWASP rules, paid managed rules) | ✓ AWS WAF (additional cost) |
| DNS | ✓ Fastest DNS globally (1.1.1.1) | Route 53 (separate service) |
| SSL/TLS | Free universal SSL | ACM certificates (free) |
| Image Optimization | ✓ Polish (paid) | ✓ via Lambda@Edge |
| Analytics | ✓ Detailed (free) | Basic (additional CloudWatch costs) |
| Zero Trust / Access | ✓ Cloudflare Access (generous free tier) | ✗ (requires separate AWS services) |
Pricing — Cloudflare Wins Clearly
Cloudflare's free plan includes unlimited bandwidth with no egress fees. This is an extraordinary offering that CloudFront cannot match. CloudFront charges per GB of data transferred out, ranging from $0.0085/GB (US/EU) to $0.12/GB (India, South America). At 10TB/month of outbound traffic, CloudFront costs ~$850; Cloudflare costs $0 on the free plan or $20/mo on Pro.
CloudFront's pricing advantage appears only when you're already paying for AWS data transfer — there is no additional egress charge when serving from CloudFront to the internet if you're already paying for EC2/S3 transfers. For sites already on AWS, this can make CloudFront competitive.
DDoS Protection
Cloudflare's DDoS protection is the industry benchmark. It is unmetered, always-on, and included in all plans including free. In 2024, Cloudflare mitigated several record-breaking DDoS attacks including a 5.6 Tbps volumetric attack. Their anycast network absorbs attacks at the edge before they reach origin servers.
AWS Shield Standard is included free with CloudFront but provides only basic protection. AWS Shield Advanced costs $3,000/month plus data processing fees. For serious DDoS protection on AWS, this cost is significant. Cloudflare wins definitively on DDoS protection value.
Edge Compute: Workers vs Lambda@Edge
Cloudflare Workers uses V8 JavaScript isolates rather than containers, resulting in near-zero cold start times (~0ms vs Lambda@Edge's 100ms+ cold starts). Workers execute in under 1ms at the edge for most operations. Lambda@Edge supports Node.js and Python but has higher latency due to container-based execution.
Workers is also significantly cheaper: 100,000 requests/day free, then $0.30/million requests. Lambda@Edge is charged per request plus compute time. For edge middleware, authentication, A/B testing and request modification, Workers is faster and cheaper.
AWS Ecosystem Integration
CloudFront's main advantage is native AWS integration. Serving content from S3 buckets, fronting EC2 applications, integrating with API Gateway, WAF, Shield, and Lambda@Edge — it all works natively within your existing AWS account and billing. For teams fully committed to AWS, CloudFront reduces complexity.
Cloudflare can sit in front of AWS origins easily. Many high-traffic sites use Cloudflare as the CDN/edge layer in front of AWS-hosted backends — getting Cloudflare's better performance and pricing while keeping AWS for compute and storage.
Final Verdict
Cloudflare wins for: standalone CDN use, DDoS protection, edge compute (Workers), free tier, pricing transparency, DNS management.
CloudFront wins for: AWS-native applications, single-bill simplicity, tighter S3/EC2 integration.
For most websites and applications in 2026, Cloudflare is the better choice as a CDN and edge platform. CloudFront makes sense primarily for organizations that want everything within the AWS ecosystem.
