Why Cloudflare?
Pixelflare was built to run on Cloudflare's infrastructure. This page explains the rationale behind that decission. The TL;DR is:
- Cost
- Performance
- Scalability
- Ease of Use
1. Cost Efficiency
For our standard scenario (20GB storage, 20GB bandwidth, 10K image transforms, 100K requests, basic database):
| Provider | Storage (20GB) | Bandwidth (20GB) | Requests (per 100K) | Compute (10K ops) | Database | Total/Month |
|---|---|---|---|---|---|---|
| Pixelflare (R2 + Workers + D1) | $0.30 | $0.00 | $0.10 | $2.50 | Included | $2.90 |
| AWS (S3 + CloudFront + Lambda@Edge) | $0.46 | $1.70 | $0.09 | $2.20 | $0.50 | $4.95† |
| Azure (Blob Storage + CDN + Functions) | $0.36 | $1.48 | $0.15 | $0.09 | $5.00 | $7.08† |
| Google Cloud (Cloud Storage + CDN + Functions) | $0.40 | $1.60 | $0.08 | $0.13 | $7.00 | $9.21† |
| Cloudinary | Bundled | Bundled | Bundled | Bundled | Bundled | $89.00 |
| Imgix | Bundled | Bundled | Bundled | Bundled | N/A | $250.00 |
Request costs include: CDN/HTTP requests, storage operations (GET/PUT/LIST), and API Gateway/Load Balancer charges where applicable.
The biggest driver behind Cloudflare's low cost, is it's zero-egress advantage - data transfer between R2 storage and Workers/CDN is totally free.
| Transfer Path | Cloudflare | AWS | Azure | GCP |
|---|---|---|---|---|
| Storage → CDN | $0.00/GB | $0.00/GB | $0.00/GB | $0.00/GB |
| Storage → Internet | N/A | $0.09/GB | $0.087/GB | $0.12/GB |
| CDN → Users | $0.00/GB* | $0.085/GB | $0.074/GB | $0.08/GB |
2. Performance
Performance is broken down into several core areas: Time to fist byte, regional latency, cold start times, image transform time and cache performance. We'll use independent benchmarks to compare the top options here.
Time to First Byte (TTFB)
TTFB is the elapsed time between a client sending an HTTP request and receiving the first byte of the server’s response. The Cloudflare Performance Benchmarks explains it well. It matters because lower TTFB reduces perceived latency, speeds up page rendering, and improves user experience and performance metrics.
| Provider | Cox (ASN 22773) p95 | Comcast (ASN 7922) p95 | Global Average | Fastest Networks |
|---|---|---|---|---|
| Cloudflare | 332.6ms | 324.2ms | 10-30ms | 44-48% |
| Fastly | 357.6ms | 323.7ms | <25ms | ~25% |
| Google Cloud CDN | 380.3ms | 353.7ms | ~353-380ms | ~15% |
| AWS CloudFront | 404.4ms | 418.8ms | <30ms (core regions) | ~10% |
| Azure CDN | ~400ms | ~400ms | <30ms (core regions) | ~8% |
| Akamai | 441.5ms | 384.6ms | <30ms | ~20% |
Regional Latency
Regional latency is the network round-trip time between a user’s geographic location and the server handling the request. It matters because higher distance-induced latency increases response times, degrades interactivity, and directly affects conversion rates, SEO, and system reliability.
| Provider | North America | Europe | Asia | South America | Africa | Oceania |
|---|---|---|---|---|---|---|
| Cloudflare | 10-20ms | 10-25ms | 15-35ms | 25-45ms | 30-55ms | 20-40ms |
| AWS CloudFront | 15-30ms | 15-30ms | 20-50ms | 40-80ms | 50-100ms | 25-50ms |
| Azure CDN | 15-30ms | 15-30ms | 25-55ms | 45-85ms | 55-110ms | 30-55ms |
| Google Cloud CDN | 12-25ms | 12-28ms | 18-45ms | 35-75ms | 45-95ms | 22-48ms |
| Fastly | 10-25ms | 10-25ms | 20-50ms | 35-70ms | 50-100ms | 25-50ms |
Cold Start Time
There's often a small delay incurred when a system must initialize a process or runtime before it can handle the first request. This is the cold start time. Long cold starts increase the tail latency and make loading slower. (see Eliminating Cold Starts)
| Provider | Cold Start Time | Warm Request Rate | Architecture |
|---|---|---|---|
| Cloudflare Workers | <5ms | 99.99% | V8 Isolates |
| AWS Lambda@Edge | 100-500ms | ~95-98% | Containers |
| Azure Functions | 200-800ms | ~93-97% | Containers |
| GCP Cloud Functions | 150-600ms | ~94-98% | Containers |
| Cloudflare (standard regions) | <50ms | 99.9% | V8 Isolates |
Image Transformation Speed
On-the-fly image processing performance
| Operation | Cloudflare (Workers + Image Resizing) | AWS (Lambda@Edge + custom) | Cloudinary | Imgix |
|---|---|---|---|---|
| Resize 2MB image | 25-50ms | 100-300ms | 50-150ms | 50-120ms |
| Format conversion (JPEG→WebP) | 30-60ms | 120-350ms | 60-180ms | 60-150ms |
| Smart crop + resize | 40-80ms | 150-400ms | 80-220ms | 80-200ms |
| Complex transformations | 60-120ms | 200-600ms | 100-300ms | 100-280ms |
| Cache hit (subsequent requests) | <5ms | <10ms | <5ms | <5ms |
Cache Performance
Cache hit ratio directly impacts cost and speed.
- Higher cache hit ratio = less origin load = lower costs
- Faster purge time = quicker content updates globally
- More edge locations = content closer to users = lower latency
| Provider | Typical Cache Hit Ratio | Global Purge Time | Edge Cache Locations |
|---|---|---|---|
| Cloudflare | 95-98% | <150ms | 330+ cities |
| AWS CloudFront | 93-96% | 1-5 minutes | 450+ PoPs |
| Azure CDN | 92-95% | 2-10 minutes | 192 PoPs |
| Google Cloud CDN | 93-96% | 30-90 seconds | ~180 locations |
| Fastly | 94-97% | ~150ms | 300+ PoPs |
Core Web Vitals Impact
How CDN performance affects Google's user experience metrics:
| Metric | Target | Cloudflare Average | AWS Average | Azure Average | GCP Average |
|---|---|---|---|---|---|
| Largest Contentful Paint (LCP) | <2.5s | 1.2-1.8s | 1.5-2.2s | 1.6-2.3s | 1.4-2.1s |
| First Input Delay (FID) | <100ms | <50ms | 60-90ms | 70-100ms | 55-85ms |
| Cumulative Layout Shift (CLS) | <0.1 | <0.05 | <0.05 | <0.05 | <0.05 |
| Time to First Byte (TTFB) | <800ms | 50-150ms | 80-200ms | 90-220ms | 70-180ms |
Performance Verdict
Cloudflare is the best all-rounder, in 44-48% of networks, and has the best cold start times (<5ms, 99.99% warm rate) and cache performance (95-98% hit ratio, 150ms global purge). However Fastly is slightly faster for some ISPs (~25% of networks) and GCP does best for Asia-Pacific performance.

Auto-Scaling Response Time
How quickly does the platform scale up to handle traffic spikes? If an image goes from zero to 100,000 requests in a fre minutes, it's important the service can handle this near-instantly with no degredation or cold start delays
| Provider | Scale-up Time | Cold Start Penalty | Warm Request % |
|---|---|---|---|
| Cloudflare Workers | Instant | <5ms | 99.99% |
| AWS Lambda@Edge | 30-60 seconds | 100-500ms | ~95-98% |
| Azure Functions | 60-120 seconds | 200-800ms | ~93-97% |
| GCP Cloud Functions | 45-90 seconds | 150-600ms | ~94-98% |

- Cost: 50-70% cheaper than cloud providers when including development time, 66-88% cheaper than specialized CDNs
- Performance: Fastest in 44-48% of networks, <5ms cold starts, 99.99% warm request rate
- Global Reach: 330+ cities, 95% of Internet within 50ms, best emerging market coverage
- Scalability: Instant auto-scaling, no cold start penalty, zero egress fees
- Developer Experience: 30 minutes to production vs 60-120 hours, integrated platform
- Reliability: 99.99% SLA, 212+ Tbps DDoS protection included, proven track record
The Cloudflare Difference
Three core advantages that competitors can't match:
- Zero egress fees = 40-60% cost savings at scale
- V8 isolates = instant scaling without cold starts
- Integrated platform = weeks of development time saved
Decision Matrix
| Your Situation | Recommended Choice | Why |
|---|---|---|
| Need production CDN quickly | Pixelflare (Cloudflare) | 30 min setup, everything included |
| Have 60-120 dev hours | AWS/Azure/GCP | $20/month savings, but $6K-12K upfront |
| Budget unlimited | Cloudinary/Imgix | Zero DevOps, premium support |
| Need specific cloud features | AWS/Azure/GCP | Deep service integration |
| Want best overall value | Pixelflare (Cloudflare) | Optimal cost-performance balance |
Why Pixelflare Chose Cloudflare
We evaluated all major platforms. Cloudflare won because:
✅ Users get enterprise-grade performance (300+ city network, <50ms latency) ✅ Users save money (zero egress fees vs $850+/year per TB bandwidth) ✅ We ship faster (30 min deployment vs 60-120 hours) ✅ Product scales automatically (instant, no cold starts) ✅ We don't pay for security (212+ Tbps DDoS protection included) ✅ Maintenance is minimal (integrated platform vs 8+ separate services)
Result: We can offer image CDN at $30/month that would cost $89-250/month on specialized CDNs or $6K-12K to build on cloud providers.
