Cloudflare

A network placed between visitors and a website: it delivers pages from nearby servers, blocks attacks, manages DNS, and also offers file storage and code hosting.

What Cloudflare is

Written from its maker's own pages, read on 28 October 2026.

Cloudflare, from Cloudflare, Inc., is a global network between a website's visitors and its servers, with security, connectivity and code running in more than 335 cities. A business routes its traffic through Cloudflare by changing its DNS settings (DNS turns a domain name into a server address).

On that path Cloudflare works as a CDN (it serves copies of pages from servers near the visitor), encrypts traffic with SSL, and filters attacks with DDoS protection, a web application firewall and bot management. Turnstile replaces CAPTCHA puzzles: a code snippet on a form checks in the background that the visitor is a real person, without collecting data for ad retargeting. Web Analytics counts visits with a small JavaScript beacon or from Cloudflare's server logs, without cookies or other data stored in the browser. A developer platform adds Workers (serverless functions on the same network), R2 file storage and D1 SQL databases.

Cloudflare is a hosted service. The free plan includes the CDN, SSL and DDoS protection; paid plans add features for a monthly fee, and developer products are billed by use. Turnstile and Web Analytics are free.
