Cloudflare and the Internet’s Builders

Cloudflare has spent well over a decade positioning itself around a single, deliberately broad phrase: helping to build a better internet. That framing sits at the center of the company’s own branding, most recently distilled into the tagline for its annual Cloudflare Connect conference, described as the place “where the Internet’s builders connect.” This article looks at who those builders actually are, how Cloudflare’s infrastructure and developer platform serve them, and how a company that started as a spam-fighting side project became one of the load-bearing pieces of infrastructure underneath a meaningful share of the modern web.

From Spam Research to Internet Infrastructure

Cloudflare’s origins trace back further than the company itself. In 2004, Matthew Prince and Lee Holloway built Project Honey Pot, a system that let website owners track how spammers harvested email addresses from their sites, an early exercise in turning raw threat data into something website operators could actually act on. Prince later met Michelle Zatlyn while pursuing his MBA at Harvard Business School, and the two, together with Holloway, refined that original spam-fighting insight into a broader idea: a “firewall in the cloud” that could protect and speed up any website without requiring its owner to install hardware or write new code. The company, officially founded on 26 July 2009 and headquartered first in Palo Alto before relocating to San Francisco, launched publicly in 2010 with exactly that pitch.

The core mechanism has remained conceptually consistent ever since, even as the product lineup built on top of it has grown enormously. A website or application using Cloudflare routes its traffic through Cloudflare’s network before that traffic reaches the origin server, and Cloudflare’s infrastructure filters, accelerates, and protects that traffic along the way. What began as a relatively narrow security and performance service has since expanded into a genuinely broad platform spanning content delivery, DDoS mitigation, DNS resolution, Zero Trust network security, and, increasingly, a full serverless application development platform. Cloudflare went public on the New York Stock Exchange in 2019 under the ticker NET, and reported 2.168 billion dollars in revenue for fiscal year 2025.

The Scale That Makes “Internet Infrastructure” Not an Exaggeration

Cloudflare’s own positioning as internet infrastructure, rather than merely a large technology vendor, is grounded in genuinely enormous scale. The company operates data centers and network points of presence in more than 335 cities around the world, placing its security, connectivity, and compute services within roughly 50 milliseconds of an estimated 95 percent of the world’s internet-connected population. This global network effect underpins essentially everything else Cloudflare offers: because traffic for such a large share of the internet already flows through Cloudflare’s infrastructure by default, the company has built a uniquely broad, real-time view of internet traffic patterns and emerging threats, insight it feeds back into its own security products for every customer on the network simultaneously.

A deliberate early strategic choice shaped how this scale actually came about. Cloudflare committed early on to a substantial free tier of its core services, a decision that prioritized broad network growth and visibility over near-term revenue. That free tier gave Cloudflare’s network genuine reach into an enormous number of the internet’s smaller, independently run websites, the personal blogs, small business sites, and independent projects that make up the long tail of the web, while its paid enterprise tiers fund the business itself. This is precisely the dynamic behind the earlier observation that a single relationship between Cloudflare and a platform like a website builder can end up shielding hundreds of thousands of small business websites at once, with individual site owners often having no idea that Cloudflare is protecting their traffic at all.

Who “The Internet’s Builders” Actually Are

The phrase itself is worth unpacking, because it deliberately spans several genuinely distinct groups of people and organizations, all of whom Cloudflare serves through different parts of its product stack.

Individual developers and small teams

At the most fundamental level, Cloudflare’s developer platform, built around a serverless compute product called Workers, targets individual developers and small engineering teams who want to build and deploy applications without managing traditional server infrastructure themselves. Workers runs JavaScript, TypeScript, and WebAssembly code directly at Cloudflare’s network edge, inside lightweight V8 isolates rather than full virtual machines or containers, allowing code to start executing with minimal delay compared to the slower cold-start times typical of more traditional serverless platforms. Alongside Workers, Cloudflare has built out a genuinely complete supporting data layer for developers: R2 for object storage that specifically eliminates the data egress fees that make comparable storage services costly at scale, D1 for SQLite-based relational databases distributed at the edge, and a globally replicated key-value store called KV, together giving a solo developer or small startup a full application stack without needing to separately assemble compute, storage, and database infrastructure from multiple different vendors.

Startups and growing businesses

For startups and scaling businesses, Cloudflare’s pitch centers on removing infrastructure complexity that would otherwise require a dedicated platform engineering team to manage. The company markets its platform explicitly around eliminating capacity planning entirely, letting a growing application scale across Cloudflare’s global network without its own engineers needing to provision additional servers, configure new regions, or manage load balancing infrastructure by hand. This matters enormously for smaller organizations specifically, since it lets a lean engineering team focus its limited time on product development rather than operational infrastructure management, historically one of the more resource-intensive and specialized parts of running any growing internet business.

Large enterprises

At the other end of the spectrum, Cloudflare serves large, established enterprises through its security-focused product lines, most notably its Zero Trust and SASE, or secure access service edge, offerings, marketed together as Cloudflare One. These products replace traditional corporate VPN infrastructure with identity-aware access controls, letting large organizations secure how their employees, contractors, and devices connect to internal applications and data without relying on the perimeter-based security models that have become increasingly outdated as workforces became more distributed. Enterprise customers also rely heavily on Cloudflare’s DDoS mitigation capabilities specifically, given the company’s network scale gives it genuine capacity to absorb and filter attack traffic at a volume most individual organizations could never handle with their own infrastructure alone.

Non-profits and vulnerable organizations

A distinct category of “builder” Cloudflare has specifically targeted since 2014 is made up of non-profits, journalists, human rights organizations, and other groups whose online presence carries real, sometimes safety-critical stakes but limited resources to defend it. Programmes like Project Galileo provide free access to Cloudflare’s security services specifically for these kinds of vulnerable public interest organizations, extending the company’s protective infrastructure to groups that would otherwise have little realistic ability to defend themselves against sophisticated, well-resourced attacks.

AI developers and agent builders

More recently, Cloudflare has increasingly framed its platform around a newer category of builder: developers building AI-powered applications and autonomous software agents. This includes infrastructure specifically designed to avoid paying for idle compute time while an application waits on a slow API call, a large language model response, or a human-in-the-loop decision, a cost structure problem that has become increasingly relevant as more applications incorporate AI components with variable, sometimes lengthy response times built directly into their core logic.

Cloudflare Connect: The Builders, In Person

The company’s positioning around “the internet’s builders” is not purely a marketing abstraction, it is literally the framing behind Cloudflare’s own flagship annual conference. Cloudflare Connect brings together developers, security architects, platform engineers, and enterprise technology leaders for several days of technical training, product announcements, and direct engagement with the engineering teams building Cloudflare’s own platform, organized around tracks spanning application development, developer and AI tooling, networking and security, and platform governance. The event’s own tagline, describing itself as where the internet’s builders connect, captures fairly directly how the company wants to be understood: not simply as a vendor selling infrastructure services, but as a central meeting point and shared foundation for the broader community of people actually constructing the modern internet’s applications, security postures, and increasingly its AI-driven systems.

What This Concentration of Infrastructure Actually Means

It is worth pausing on the broader implication of Cloudflare’s scale, since it carries real weight beyond the convenience it offers individual builders. Because such a substantial share of global internet traffic now flows through a relatively small number of infrastructure providers, of which Cloudflare is among the largest, an outage or a significant policy decision at that layer has consequences that ripple far beyond any single customer. This has occasionally put Cloudflare in a genuinely difficult position, most notably when the company has had to decide whether to terminate service for specific customers whose content raised serious ethical concerns, decisions that Cloudflare’s own leadership has publicly acknowledged sit uncomfortably with the company’s general stated preference for remaining a neutral, content-agnostic infrastructure provider rather than an arbiter of acceptable online speech.

This tension is a direct byproduct of Cloudflare’s own success in becoming genuinely foundational infrastructure for such a broad swath of “the internet’s builders.” A company whose free tier and technical advantages made it the default choice for an enormous number of independent developers, small businesses, and organizations of every kind has, almost as a side effect of that success, become one of a small number of chokepoints whose decisions carry outsized weight across the internet as a whole, a responsibility considerably heavier than the one implied by the comparatively modest, developer-friendly framing of simply helping people build things faster and more securely.

Wrapping Up

Cloudflare’s journey from a spam-tracking side project to a company whose infrastructure sits between a meaningful share of the internet and the rest of the world reflects a genuinely coherent, if ambitious, strategic throughline: give builders of every size, from a solo developer deploying a weekend project to the largest global enterprises, the same underlying network, security, and compute infrastructure the company itself relies on, and let network effects and free-tier accessibility do the work of making that infrastructure genuinely ubiquitous. The framing of “the internet’s builders” captures something real about who actually uses Cloudflare’s platform today, a genuinely broad coalition spanning individual developers, growing startups, large enterprises, resource-constrained non-profits, and now a fast-growing wave of AI and agent developers, all served through the same underlying global network. Whether that concentration of infrastructure ultimately serves the internet’s long-term health as well as it serves any individual builder’s convenience remains a genuinely open question, one Cloudflare’s own leadership has shown a real willingness to grapple with publicly rather than waving away, even as the company’s practical importance to how the modern internet actually functions continues to grow.
