How do I choose between Cloudflare, Fastly, and CloudFront?

Here’s the practical way to choose:

Quick take

• Cloudflare: best default if you want the broadest “all-in-one” edge platform with strong security, DNS, CDN, WAF, bot protection, and easy-to-use developer features.
• Fastly: best if you need high control, very low-latency edge delivery, real-time config changes, and strong performance tuning.
• CloudFront: best if you’re already deep in AWS and want tight integration with S3, ALB, Lambda, IAM, WAF, Shield, and the rest of AWS.

Choose based on your main goal

Pick Cloudflare if you want:

• Simple setup and broad capabilities
• Strong DDoS protection and WAF out of the box
• A large global network
• CDN + DNS + security + edge compute in one place
• Good cost/value for many general workloads
• Developer-friendly edge products (Workers, KV, R2, etc.)

Good for: SMBs, SaaS, APIs, websites, security-conscious teams, and teams that want to reduce vendor sprawl.

---

Pick Fastly if you want:

• Fine-grained CDN behavior and performance tuning
• Very fast purging/invalidation and config propagation
• Strong support for advanced caching logic
• A platform favored by teams with sophisticated delivery needs
• Edge compute via Compute@Edge with strong runtime performance

Good for: media, large-scale content delivery, engineering-heavy organizations, and companies with complex traffic rules or custom caching strategies.

---

Pick CloudFront if you want:

• The simplest fit with AWS infrastructure
• Native integration with S3, ALB, API Gateway, Lambda, WAF, Shield, IAM, and ACM
• A managed CDN with a familiar AWS operational model
• Good reliability and global coverage without adding another major vendor

Good for: AWS-native architectures, internal teams already standardized on AWS, and workloads where operational simplicity inside AWS matters more than best-of-breed edge features.

Simple decision rules

• If you’re not sure: start with Cloudflare.
• If you are all-in on AWS: choose CloudFront.
• If you need maximum CDN control/performance tuning: choose Fastly.

What to compare directly

1. Security

• Cloudflare: usually the strongest and easiest security bundle.
• Fastly: strong security options, but often more builder-oriented.
• CloudFront: solid when paired with AWS WAF/Shield, but less “batteries included.”

2. Edge compute

• Cloudflare Workers: very popular, easy, broad ecosystem.
• Fastly Compute@Edge: great for low-latency and advanced use cases.
• CloudFront: Lambda@Edge and CloudFront Functions are useful, but more AWS-specific and sometimes less ergonomic.

3. AWS integration

• CloudFront wins clearly.

4. Ease of use

• Cloudflare is usually easiest to adopt.
• CloudFront is easiest if your team already knows AWS well.
• Fastly can be more technical but very powerful.

5. Performance

All three are fast enough for most use cases. The real difference is often:

• where your users are,
• how you cache,
• what your origin is,
• and how much control you need.

Rule of thumb by company type

• Startup / SMB: Cloudflare
• AWS-first enterprise: CloudFront
• Media / high-performance delivery / advanced caching: Fastly

A very short recommendation

If you want the safest general recommendation:
Cloudflare first, Fastly second, CloudFront if AWS-native.

2. a cost comparison, or
3. a recommendation for your specific architecture.
