Cloudflare

What it is

Cloudflare is the world's leading web infrastructure and security company. It acts as a protective shield and an accelerator for millions of websites. By routing traffic through its massive global network, it blocks DDoS attacks, speeds up content delivery via its CDN, and provides a 'serverless' environment through Cloudflare Workers. It is the most accessible way to make your website faster, safer, and more reliable with just a simple DNS change. Who it is for: almost any site owner, because the free plan gives DNS, a global CDN, TLS certificates and DDoS protection at no cost, and most small sites never need more. Developers get a second product family on top: Workers for edge code, Pages for static hosting, R2 for object storage with no egress fees, and D1 and KV for data at the edge. Where it falls short: the more of that family you adopt, the harder it is to leave, because Workers and its bindings do not run anywhere else. The Pro and Business plans add image optimisation, a WAF ruleset and better analytics, but some features that look free have paid tiers once traffic grows, and Enterprise pricing is by negotiation. Support on free and Pro plans is community and ticket based. Bunny is cheaper for pure CDN traffic; Fastly is stronger for programmable caching at scale; Cloudflare wins on breadth and on the price of getting started.
