Cloudflare

Cloudflare runs a global network that handles web performance, DDoS protection, DNS, content delivery and Zero Trust network access for websites, apps and companies. Its developer platform lets teams deploy code, including AI agents, to servers spread across more than 330 cities. Many large companies use its security and delivery services, and it offers a free tier for small projects.

The company is headquartered at 101 Townsend Street in San Francisco. Its products are sold through a plan-based pricing page, and larger customers work with a sales team. Free accounts can be started online without a credit card, and the company also sells a range of paid plans for growing sites and organizations.
