Cloudflare K2 is a serverless event streaming service built directly on top of R2 object storage for high-scale data movement and long-term retention. By decoupling producers and consumers at the edge, K2 enables durable, ordered log streams without the operational overhead of traditional broker clusters.

AI Search is now generally available. It embeds image pixels directly for visual search, runs optical character recognition on scanned PDFs, accepts files up to 10 MiB, and works with any chat model. Here's what's new and how pricing works.

AI Gateway User Insights now adds task, model, turn, and user categories to help teams understand AI adoption and make better model decisions. This is available free to AI Gateway users.

Ayush Kumar and Frank Meszaros

Cloudflare Containers now start 6x faster, let your agent choose each sandbox's image and instance type at runtime, and support filesystem snapshots in public beta, all controlled from a Durable Object.

Thomas Gauvin, Rushil Mehra, Gabi Villalonga Simón, and Thomas Lefebvre

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.

Sharon Goldberg and Tiago Silva

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.

James Anderson and Matt “TK” Taylor

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.

Guy Bedford and Mitch Foley

The Internet is changing more today than at any point since Cloudflare launched back on September 27, 2010. As automated traffic surpasses human activity, we reflect on the rise of AI agents, new creators, and how we can help build a fair, sustainable future for the web.

Matthew Prince and Michelle Zatlyn

External security researchers at Accomplish identified a vulnerability in Cloudflare Containers that could expose residual disk data from previous workloads. We explain how the issue worked, how we investigated it, and the steps we took to remediate it.

Rushil Mehra, Cody Roseborough, Avishek Sarkar, and Hrushikesh Deshpande

Python Workers allow developers to run Python web frameworks and AI orchestration libraries natively in the Cloudflare Workers runtime. You can seamlessly integrate with Cloudflare's ecosystem including D1, R2, and Workers AI without writing any JavaScript glue code.

Gyeongjae Choi, Dominik Picheta, and Hood Chatham

A modern storefront can look healthy while malicious JavaScript quietly siphons revenue, hijacks clicks, or rewrites analytics. See how Cloudflare's machine learning models surface evasive client-side attacks for analyst investigation.
