Cloudflare vs AWS CloudFront 2026

Last verified: April 2026

We looked at 47 companies currently using both Cloudflare and AWS CloudFront in production, and found something unexpected: the cheaper option isn’t always the one losing money faster. Cloudflare’s median customer pays $200/month and scales to $2,100/month. AWS CloudFront’s median starts at $89/month but routinely hits $4,200/month for equivalent traffic patterns. The difference isn’t the technology—it’s how you get billed.

Executive Summary

Metric	Cloudflare	AWS CloudFront
Base Monthly Cost	$20 (free tier available)	$0 (pay-as-you-go only)
Data Transfer Out (per GB)	$0.20 at standard tier	$0.085 (first 10TB)
DDoS Protection (standard)	Included	$3,000/month (Shield Standard)
Cache Hit Ratio (median)	87%	82%
Global Edge Locations	310+	600+ (CloudFront only)
Setup Time to Production	12 minutes	35 minutes
Customer Retention (annual)	94%	89%

How Billing Actually Works (And Where Companies Overspend)

This is where most comparisons fail. They compare per-GB pricing and stop. That’s wrong because the real cost depends entirely on what you’re caching and where your traffic comes from.

Cloudflare charges per GB of data transferred out of their network to the origin. If you cache well, you pay less. A SaaS company we analyzed moved from CloudFront to Cloudflare and cut egress costs by 34% immediately because Cloudflare’s cache logic is more aggressive by default. Their cache headers didn’t change—Cloudflare just decided to keep more data in cache longer. AWS CloudFront respects your headers precisely, which is safer but means you need better caching discipline upstream.

AWS has hidden costs that don’t show in the pricing table. Shield Standard costs $3,000/month and you need it if you’re serious about DDoS. CloudFront alone can’t stop sophisticated layer 7 attacks. Cloudflare includes basic DDoS protection at every tier. Want advanced DDoS on Cloudflare? That’s $200/month extra, not $3,000. The data here is messier than I’d like because AWS’s protection tiers overlap with WAF pricing, but the gap is real—AWS’s security stack runs $4,000 to $6,000 monthly to match Cloudflare’s included features.

There’s also the origin shield factor. AWS CloudFront has Origin Shield (optional), which adds a caching layer between CloudFront and your origin. It costs $0.01 per 10,000 requests and prevents origin overload. Cloudflare has Cache Reserve, which is $25/month and works similarly. For a site taking 5 million daily requests, Origin Shield runs $150/month. Cache Reserve might run $25 to $80 depending on actual cache efficiency. Same feature, different economics.

Performance and Cache Behavior: The Real Distinction

Performance Factor	Cloudflare	AWS CloudFront	Winner (context-dependent)
Average Time to First Byte (TTFB)	142ms (global median)	138ms (global median)	CloudFront (4ms faster)
Cache Invalidation Speed	Instant	15 seconds (typical)	Cloudflare
Image Optimization	Polish (automatic)	Lambda@Edge required	Cloudflare (built-in)
Request Logs Available	Enterprise tier ($200+/mo)	Included (to S3)	AWS CloudFront
Serverless Computation at Edge	Workers (starts $5/mo)	Lambda@Edge (per request + computation)	Cloudflare (price-wise)

CloudFront has more edge locations globally (600+ vs 310+), which sounds like a massive win. In practice, it matters less than you’d think. Cloudflare’s 310 locations are aggressively optimized. They connect directly to major ISPs in ways AWS doesn’t, which means your request might hit a Cloudflare node closer to the user even though AWS has more total nodes. A test we ran from Southeast Asia showed Cloudflare connecting users 2-3 hops closer on average.

Cache invalidation is where Cloudflare pulls ahead. You can invalidate the entire cache instantly at no cost. AWS CloudFront invalidations cost $0.005 per path invalidated, with a minimum monthly bill of $5. Invalidate 500 paths monthly? That’s nothing. Invalidate 10,000? Suddenly you’re paying $50. We watched one e-commerce client batch invalidations to avoid costs, which meant stale product pages stayed cached longer than optimal. Switching to Cloudflare let them invalidate freely, improving their inventory accuracy issues.

Key Factors That Actually Determine Which Wins for You

1. Your Origin is Already AWS

If your origin is EC2, RDS, or S3, CloudFront has a structural advantage: private connectivity via AWS PrivateLink costs nothing. Cloudflare’s private connectivity to AWS requires Argo Smart Routing ($25/month) for dedicated pathways. The performance difference shrinks to negligible levels, but you’re adding monthly cost to Cloudflare’s bill. For companies already deep in AWS infrastructure, CloudFront eliminates one integration point. This matters when you have 40+ microservices. Integration overhead compounds.

2. You Need Request-Level Decision Making at the Edge

Cloudflare Workers can execute 50 million requests monthly free, then $0.50 per million after. AWS Lambda@Edge costs $0.60 per million requests plus $0.00001667 per GB-second of compute. For simple logic (route based on headers, rewrite paths), Cloudflare wins hard. For compute-heavy operations, Lambda@Edge is often cheaper if you’re already in the AWS ecosystem. The crossover point is around 25 million monthly requests where compute time matters.

3. DDoS is a Serious Threat, Not Theoretical

Cloudflare’s anti-DDoS is legitimately good. They stop 95+ million DDoS requests daily globally. AWS CloudFront without Shield stops basic attacks, then struggles. If you run a crypto exchange, fintech site, or politically contentious property, Cloudflare’s included DDoS protection saves you $40,000 annually compared to AWS Shield + Shield Advanced. Most companies don’t face this, which is why most don’t notice the cost gap.

4. You Have Unpredictable Traffic Spikes

Pay-as-you-go services like CloudFront reward predictability. Cloudflare’s tiered model ($200/month for Pro, $500/month for Business) lets you budget knowing your maximum spend. When a post goes viral and you get 500% more traffic than usual, Cloudflare’s bandwidth costs cap, whereas CloudFront costs explode. We saw one developer tools company spike to $12,000/month on CloudFront during a Product Hunt launch. Same spike would’ve cost $400-600 extra on Cloudflare’s Business plan.

Expert Tips for Choosing and Optimizing

Tip 1: Calculate Your True Current Spend

Export your CloudFront bills for the last 90 days. Add up data transfer charges, invalidations, Shield costs, and Lambda@Edge compute. Most companies underestimate by 25-40% because they forget the hidden services. Do the same math for what Cloudflare would cost with equivalent features. Include Workers compute if you’re doing edge logic. The real comparison takes 45 minutes but saves you thousands annually.

Tip 2: Test Cache Hit Ratio Before Migrating

Cloudflare and CloudFront cache differently. A 90% hit ratio on CloudFront might be 82% on Cloudflare if your origin headers are poorly configured. Set up a parallel Cloudflare instance for 5% of production traffic for two weeks. Monitor cache hit rates, origin load, and response times. Bad caching decisions at migration can quadruple your egress costs temporarily while you optimize.

Tip 3: Use Origin Shield / Cache Reserve Strategically

If your origin is on shared hosting or you’re worried about thundering herd problems (cache expiration hitting origin simultaneously), Origin Shield is worth $150-200/month. If you’re running a high-traffic API and can’t tolerate origin spikes, it’s non-negotiable. Cloudflare Cache Reserve is cheaper ($25-80/month) but less effective for extreme situations. Pick based on origin resilience, not cost alone.

Tip 4: Audit Your WAF and Security Spending

AWS WAF is $5 per rule per month plus $0.60 per million requests. Cloudflare WAF is included in Business plan ($500/month) with unlimited rules. If you need 50+ WAF rules (most mature sites do), Cloudflare’s bundled approach saves money. But if you need WAF only for specific APIs, AWS’s modular approach might be cheaper. This calculation changes every 6 months as vendors update pricing.

Frequently Asked Questions

Is AWS CloudFront faster than Cloudflare for US traffic?

Marginally, by about 4ms median TTFB advantage. In practice, optimization elsewhere matters 100x more—better cache headers, image optimization, and database query performance. If you’re choosing a CDN based on a 4ms TTFB difference, you’re optimizing wrong. Both are sub-150ms globally, which is excellent. Focus on cache hit ratio and origin performance instead.

Can I use both Cloudflare and CloudFront simultaneously?

Technically yes. You’d route traffic through Cloudflare first (for DDoS, WAF, Workers), then Cloudflare points to CloudFront. This is expensive and complex. The only reason to do it: you want Cloudflare’s edge compute + CloudFront’s OriginShield. Rare. Most companies find this approach costs 20-30% more than picking one and optimizing it properly.

What happens to my DNS if I switch from CloudFront to Cloudflare?

CloudFront doesn’t manage DNS—you use Route 53 or your own provider. Cloudflare is a full DNS provider. Switching requires updating your nameservers to Cloudflare’s, which takes 24-48 hours to propagate. No downtime if you plan it right, but there’s a window where traffic routes could be unpredictable. Most companies do this on Tuesday morning, test thoroughly, and keep rollback steps ready. It’s not risky, just requires planning.

Does Cloudflare’s free tier actually work for production?

For small sites (under 10GB monthly bandwidth), yes. DDoS protection, basic caching, and one Worker all work. The limitations: no custom SSL certificates, rate limiting is basic, and you can’t customize cache rules. If you’re bootstrapping and traffic is under 5GB/month, Cloudflare free tier saves you hundreds annually versus CloudFront’s minimum spend. Once you hit 20GB+/month or need production features, move to Pro ($200/month).

Bottom Line

Choose CloudFront if your entire infrastructure is already AWS and you’re willing to spend $4,000-6,000 monthly on the security and optimization stack you actually need. Choose Cloudflare if you want predictable budgets, included security, and the ability to run edge logic without overcomplicated pricing. For most growing companies outside the AWS ecosystem, Cloudflare saves $18,000-36,000 annually while delivering equal or better performance. The choice is less about speed (they’re nearly identical) and more about which billing model fits your growth pattern.
