We’ve been working on something new — a platform for running containers across Cloudflare’s network. We already use it in production, for AI inference and more. Today we want to share an early look at how it’s built, why we built it, and how we use it ourselves.

One of the main laws that applies to almost everything in our lives, including building digital products, is Murphy’s Law: “Anything that can go wrong will go wrong.” Our goal is to prevent things from going wrong and, if they do, mitigate the consequences. In this article, Victor Ponamarev explores different strategies for preventing users from making mistakes.

Transforming team dynamics by shifting focus from infrastructure management to innovation and delivering value.

To celebrate Builder Day 2024, we’re shipping 18 updates inspired by direct feedback from developers building on Cloudflare. This includes new capabilities, like running evals with AI Gateway, beta products like Queues and Vectorize graduating to GA, massive speed improvements to KV and Workers AI, pricing simplifications, and bringing key features from Pages into Workers.

Cloudflare’s Startup Program now offers up to $250,000 in credits for companies building on our Developer Platform. The program relaunch uses clear and predictable credits so that you can easily see how usage impacts future pricing.

Today, we’re announcing up to 3x faster KV hot reads, with all KV operations faster by up to 20ms. And we want to pull back the curtain and show you how we did it.

Traditional cloud storage is inherently slow because it is accessed over a network and must synchronize many clients. But what if we could instead put your application code deep into the storage layer, such that your code runs where the data is stored? Durable Objects with SQLite do just that.

Whether you want the fastest inference at the edge, optimized AI workflows, or vector database-powered RAG, we’re excited to help you harness the full potential of AI and get started on building with Cloudflare.

With a new generation of data center accelerator hardware and using optimization techniques such as KV cache compression and speculative decoding, we’ve made large language model (LLM) inference lightning-fast on the Cloudflare Workers AI platform.

What’s a ktls I started work on ktls and ktls-sys , a pair of crates exposing Kernel TLS offload to Rust, about two years ago . kTLS lets the kernel (and, in turn, any network interface that supports it) take care of encryption, framing, etc., for the entire duration of a TLS connection… as soon as you have a TLS connection. For the handshake itself (hellos, change cipher, encrypted extensions, ce

With this public preview, we’re unlocking the context of your code and collaborators—and taking the next step in infusing AI into every developer’s workflow.

For this year’s Cybersecurity Awareness Month, GitHub’s Bug Bounty team is excited to offer some additional incentives to security researchers!

Cloudflare is now verifying WhatsApp’s Key Transparency audit proofs to ensure the security of end-to-end encrypted messaging conversations without having to manually check QR codes. We are publishing the results of the proof verification to https://dash.key-transparency.cloudflare.com for independent researchers and security experts to compare against WhatsApp’s. Cloudflare does not have access t

We’re reintroducing our Make Designs feature with some key improvements, including a new name—First Draft

So far, most attention to Generative Artificial Intelligence (GenAI) in software development is on generating code. But we believe there is as much, if not more, value in understanding existing code - particularly long-lived, large, and complex legacy systems. We have been experimenting with GenAI for modernization with our clients, embodied in a tool called CodeConcise, which combines a Large Lan

I recently launched a brand new version of this blog, and in this post, I share how it’s built! We’ll examine the tech stack and see how all of the pieces fit together, as well as dig into some of the details to see how they work.
