Cloudflare Workers

Cloudflare Workers is adding opt-in support for post-quantum-resistant algorithms ML-KEM and ML-DSA. You can try it today.

You can now use built-in error monitoring in Cloudflare Workers to group production failures and send stack traces, logs, traces, and application context directly to a coding agent to investigate further and open a pull request.

We’re building CryptoLabe, an internal AI-powered tool that discovers cryptography across our codebase, surfaces dependencies, and helps us progress toward a full post-quantum migration by 2029. Here’s what we’ve learned so far.

Vinext 1.0 graduates from an AI experiment to a production-ready framework, letting developers run Next.js apps on Vite. This release brings advanced cache warming, broader compatibility, and an automated testing pipeline.

EmDash 1.0 is a stable, open source CMS built for Astro, with agent-friendly workflows, secure sandboxed plugins, and a decentralized registry that keeps publishers in control.

With the new experimental support for the Emscripten target in Rust Workers, many previously unsupported Rust libraries and applications can now be built and deployed directly to Cloudflare’s global Workers platform, including upcoming support for Tokio async.

Workers now enables Node.js compatibility by default, supports applications up to 64 mebibytes, and adds a URL-based module registry with import.meta, lazy compilation, shared code caches, and clearer errors.

Logan Gatlin and James Snell

We migrated the Cloudflare Blog to EmDash to prove our stack at massive scale. Here is how we stress-tested performance, safely routed production traffic, and redesigned the frontend experience.

Introducing Cloudflare Access for Workers. Attach an Access policy directly to a Worker and it applies everywhere that Worker runs — routes, custom domains, workers.dev, and previews — automatically.

Our latest Agents Week has come to a close. Here’s a recap of all the announcements we made from Wallets to Radar.

Shelley Jones, Ann Ming Samborski, and Kathy Liao

Cloudflare OS is an open-source platform that lets everyone in your company build apps, automate work, and safely access internal systems, shaped around what your organization knows and how it operates

Phillip Jones and Dan Carter

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

Brendan Irvine-Broque

wrangler dev now produces structured traces for every local request. Your coding agent can hit a single API to pinpoint exactly what failed and why — no deployment required.

Zin Khant, Nickhil Pattikonda, and Nevi Shah

By replacing manual issue verification with isolated AI subagents running in GitHub Actions, the Astro maintainers reduced open issue count by 85%. This post explores the architecture behind automated bug reproduction, patch verification, and preview releases.

Matthew Phillips

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.

Matt Carey and Aron Carroll

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.

Mar Witek and Thomas Rubini

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

Dominik Picheta and Gyeongjae Choi

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.
