About Cloudflare
Cloudflare started as a CDN and DDoS protection layer and has expanded into a full developer platform. The free plan covers unlimited bandwidth for CDN and DDoS mitigation — genuinely free with no bandwidth billing, which undercuts every other CDN. Pro is $20/month, Business $200/month. Workers (serverless compute at the edge) are free up to 100K requests/day, $5/month (10M requests included) after that. Pages is a Vercel and Netlify competitor for static sites and server-side rendering at the edge, free for unlimited sites. R2 (S3-compatible object storage) charges zero egress fees, directly undercutting AWS S3. D1 (SQLite at the edge), Queues, KV, and Durable Objects round out the developer platform. The critical limitation: Workers runs V8 isolates, not Node.js — code using `require('fs')`, Node buffers, or Node-specific modules won't work. Cold starts are essentially zero (isolates vs containers). Competes with AWS Lambda@Edge, Vercel Edge Functions, and Fastly. The free CDN tier alone is worth using for any public-facing site regardless of what else you run.

Pros
- Incredibly generous free tier
- Global CDN with unlimited bandwidth
- Workers is a powerful edge computing platform
- R2 has no egress fees and is S3 compatible
- Always-on DDoS protection
- Fast DNS propagation
Cons
- Workers has execution time limits
- D1 database is still maturing
- Complex pricing across many products
- Support on free tier is community-only
- Pages sites have build time limits
- Not a full cloud replacement for AWS/GCP
Best For
- CDN and DDoS protection for any public site (free tier is genuinely unlimited)
- edge-native serverless functions where V8 isolate constraints are acceptable
- object storage where S3-compatible APIs are needed without egress fees (R2)
- static site hosting that needs global CDN without paying per-GB for bandwidth
Not Ideal For
- Node.js-specific code that uses `fs`, native modules, or Node APIs not in the Web platform
- teams that need traditional server environments (Workers is not a VPS)
- complex stateful workloads that need more than KV, D1, or Durable Objects
Potential Deal Breakers
- Workers runtime is V8 isolates, not Node.js — Node-specific modules will not work
- Durable Objects and D1 are new enough that production reliability is still being established
- vendor lock-in risk: Workers APIs are Cloudflare-specific and not portable
Data & Privacy
CDN and security provider. Cloudflare processes web traffic but states it does not sell personal data or mine customer data. DNS query logs retained for limited periods. Workers and R2 storage data stays in your control. Privacy-focused DNS resolver (1.1.1.1). SOC 2 and ISO 27001 certified.

Hands-on tested May 2026
Signup Experience
Email signup only. Free plan activates instantly with no credit card needed. DNS propagation after nameserver switch takes a few hours. Dashboard covers CDN, DNS, SSL, firewall, and Workers in one place -- initially overwhelming but well-organized.
For Home Users
Free plan is genuinely exceptional -- full CDN, automatic SSL, DDoS protection, and fast DNS. One of the most valuable free products available anywhere. Adding a site takes minutes and performance improvements are immediate. Highly recommended for any personal site or project.
For Business Users
Pro at $20/mo adds WAF rules, image optimization, and mobile performance features. Business at $200/mo unlocks custom WAF rules and advanced analytics. Workers and R2 on paid plans enable edge compute and storage. Cloudflare has become infrastructure for a significant portion of the web -- reliability and global reach are unmatched.
Our Verdict
Cloudflare's free CDN tier is a no-brainer for any public-facing site — unlimited bandwidth with no credit card is remarkable. The developer platform (Workers, R2, D1) is genuinely interesting if you can work within the V8 isolate constraints. The R2 zero-egress-fee pricing is a direct attack on AWS S3 that makes sense for high-download workloads.
Price History
Cloudflare expanded free Workers from 100K to 500K requests/day
Cloudflare continues to make its free tier the most competitive in the industry. Workers, R2 storage, and D1 database all got expanded free allocations. The strategy is to lock developers into the ecosystem early.
