Cloudflare

Cloudflare provides cloud services for securing websites, delivering content, connecting employees, and running applications. Its global network combines CDN, DDoS protection, web application firewall, and bot management services with Zero Trust controls for workforce access. Developers use Cloudflare Workers, storage services, and built-in AI inference to build applications and agents without managing servers. These services run on the same network, bringing application delivery, security, and development into one platform for startups and enterprises.

Founded in 2009 by Matthew Prince, Michelle Zatlyn, and Lee Holloway, Cloudflare grew out of Project Honey Pot’s work tracking Internet abuse and publicly launched in 2010. Prince remains CEO, while Zatlyn is president. Its engineering contributions include workerd, the open-source JavaScript and WebAssembly runtime underlying Workers. It supports web-standard APIs and runs multiple services in separate isolates within one process, reducing communication overhead. Developers can also use it to self-host Workers applications or test them locally.

Cloudflare combines free entry tiers with paid website plans, workforce subscriptions, and usage-based developer services. It reported that more than 45% of Fortune 500 companies were paying customers as of June 2026. Its completed acquisition of Replicate in December 2025, for $57.4 million in total cash purchase consideration, added a platform that lets developers deploy and run AI models.
