Agents can write code faster than teams can review, deploy, and maintain it. Today we’re introducing the Agent Development Lifecycle and the Cloudflare primitives that underpin it

Agents need more than just a container to scale. We're introducing @cloudflare/computer, an agent runtime that dynamically orchestrates between fast, efficient isolates and full Linux containers to give every agent a computer of its own.

One coding agent can write a Python Worker and another can write a JavaScript Worker. At runtime, those Workers can exchange references to live objects and call their methods without defining APIs, schemas, or serialization code

Serving frontier models like Kimi and GLM means fighting for GPU memory. Here's how we quantize KV caches, compress model weights, and add integrity checks to serve them faster, cheaper, and safely.

Cloudflare has launched a new Billable Usage API for accounts, giving developers and FinOps teams single-endpoint programmatic visibility into cost and usage across all self-serve products. Built around the FOCUS specification, track spend seamlessly alongside the rest of your cloud stack.

Cloudflare Workers now support inbound TCP connections via Spectrum, allowing direct socket forwarding to Durable Objects and Containers. Developers can run full-duplex gRPC applications or leverage automatic gRPC-to-gRPC-web translation directly within Workers.

Agents Week explores how cloud infrastructure must evolve to serve autonomous agents rather than human browsers. Join us as we unpack the storage, execution, and security primitives needed for an agent-native web.

Last year we made every Cloudflare server a Media over QUIC (MoQ) relay. Now the new provisioning API lets you create your own isolated relay and control who can publish and who can only watch.

We moved cdnjs, serving 9 billion requests a day, entirely onto Cloudflare's Developer Platform. That means we’re running one of the Internet's busiest open-source CDNs on our own building blocks, and we pushed Workflows and Workers limits higher for everyone.

Cloudflare now supports post-quantum (PQ) authentication when connecting to customer origin servers via Authenticated Origin Pulls and Custom Origin Trust Store. This is the first step towards providing PQ authentication for all Cloudflare products.

Cloudflare Radar tracked Internet disruptions driven by natural disasters, government-mandated shutdowns, and DNSSEC key rollovers over the last quarter. This post analyzes traffic telemetry to explain how these events impacted global connectivity.

pvcli is a curl-like tool designed to simplify the testing of complex privacy protocols like OHTTP.

By doing in-depth testing, we found nearly 70% of BGP paths experience ORIGIN attribute rewrites by transit providers seeking traffic advantages. We examine the global impact of this practice and argue for deprecating ORIGIN in route selection.

Perhaps you’ve seen something that should sail out of cache get dragged back to the origin by a stray Set-Cookie or Cache-Control, headers that can be difficult to change on the origin itself. Cache Response Rules is the fix, applied at the right time.

We analyzed global HTTP traffic to explore how kickoff times, streaming habits, and hydration breaks reshaped online activity worldwide. From late-night traffic surges to halftime browsing spikes, here is how the world connected during the global tournament.

Cloudflare Internal DNS brings authoritative and recursive DNS for private networks to the same global network and control plane that runs Cloudflare's Zero Trust, networking, and public DNS.

Cloudflare has deployed two WAF rules in response to high-severity vulnerabilities disclosed to us by the WordPress security team. The new rules protect all Cloudflare customers using affected WordPress versions, but customers should still update immediately to a patched release

When a failed DNSSEC key rollover took down the .al TLD, we deployed a Negative Trust Anchor to restore resolution. This time, though, clients didn't have to take our word for it: 1.1.1.1 returned EDE 33, a new DNS error code that signals directly in the response that DNSSEC validation was bypassed.

Precursor, our new continuous behavioral validation engine for bot management, offers visibility into how humans and bots actually interact across the full user journey. By turning session-level behavior into bot detection signals, it identifies advanced automation with higher precision — while reducing friction for legitimate users.

Smart Tiered Cache allows for precise upper tier selection for origins hosted on AWS, GCP, Azure, and Oracle Cloud with customer-provided cloud region hints.
