Cloudflare

Overview

Cloudflare is an internet infrastructure company that provides networking, security, developer platform, and edge computing products. For AI Product Managers, Cloudflare matters because it sits at the intersection of global delivery, APIs, edge execution, and developer tooling—areas that increasingly shape how AI-powered products are built, deployed, and scaled.

In the newsletter context, Cloudflare stood out for two reasons: first, its developer-friendly DNS resolver API for 1.1.1.1 enabled rapid prototyping of a DNS lookup UI; second, it used AI-assisted development to recreate much of the Next.js API surface for its Workers platform, showing how infrastructure companies can accelerate platform compatibility and improve developer experience. This makes Cloudflare especially relevant for PMs building edge-native apps, AI-enabled developer tools, or products that depend on low-latency global inference and APIs.

Key Developments

• 2026-03-03: Cloudflare used AI to rebuild the Next.js API for its Workers platform into V-Next in just three days, reaching 94% API coverage. The result enabled more Next.js apps to run on Cloudflare Workers, with reported gains of up to 4.4× faster builds and 57% smaller bundles.
• 2026-03-23: Simon Willison highlighted Cloudflare's CORS-enabled JSON API for 1.1.1.1, then used Claude Code to build a UI for querying Cloudflare's DNS resolvers (1.1.1.1, 1.1.1.2, 1.1.1.3). The example showed how accessible infrastructure APIs can unlock fast experimentation and useful developer-facing tools.

Relevance to AI PMs

• Validate edge deployment strategy: Cloudflare is a strong reference point for PMs evaluating whether AI features, APIs, or agent workflows should run closer to users at the edge for latency, privacy, and cost reasons.
• Study AI-accelerated platform work: The V-Next example is a practical case of using AI to speed up framework compatibility and developer platform delivery. PMs can apply similar thinking to migration tooling, SDK generation, integration layers, and API surface expansion.
• Prioritize developer-friendly APIs: The 1.1.1.1 JSON API example shows how simple, accessible infrastructure endpoints can create outsized value for developers. AI PMs building platform products should invest in APIs that are easy to test, compose, and turn into tools quickly.
