Python Workers are now generally available
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.
Open-Sourcing Rebalancer: A Generic, High-Performance Library for Solving Assignment Problems
We’re open-sourcing Rebalancer, the assignment-problem solver that has been used to solve resource allocation problems throughout Meta for over nine years. Rebalancer separates several related concerns: how to specify an assignment problem, how to store it efficiently in memory, how to solve it, and how to debug it. This separation of concerns is crucial to [...] Read More... The post Open-Sourcin
Inside Petal: Building the World’s First Petabit-Class Transoceanic Subsea Cable
Petal, the next step in Meta’s subsea innovation, will be the first subsea cable to deliver petabit capacity at transoceanic distances, connecting France and the United States over approximately 7,000 km (4,300 mi). Expected to enter service in 2029, it will be the first subsea cable system to deploy multi-core fiber technology at scale, doubling [...] Read More... The post Inside Petal: Building
Notes on discrete-time Fourier series and transform
The following are my notes on discrete-time Fourier series (DTFS), as well as the discrete-time Fourier transform (DTFT). These topics serve as an important theoretical underpinning to the digital processing of signals by computers using the DFT (which will be covered in a future post). For discrete-time signals, we use …
Saving another 100TB of RAM with math (and Rust)
Cloudflare's global network is immense but not limitless. As we look for small ways to trim our resource usage, we sometimes get lucky and we can cut significantly more. Here’s how we reduced one of our Pingora-based service's RAM usage with statistics.

When scanners miss the attack: how Cloudflare Client-Side Security protects storefronts
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.
Stop Treating CSS Container Queries Like Traditional Media Queries
Despite broad browser support, container queries remain surprisingly underused and frequently misunderstood. Let’s look at how they differ from media queries, when to reach for each, and how container queries help reusable components respond naturally to the contexts in which they appear. - CSS - Tools - Techniques

Quality and reliability have always been a point of pride for Spotify. We run an extraordinarily complex...
Have it both ways: stay discoverable in search while disallowing AI training
Cloudflare is giving site owners a way to stay discoverable while disallowing AI training. New controls and an Accountable designation establish a shared model with Apple, Google, and Microsoft.
Give every teammate and agent the right level of access to your Workers
You can now scope access to individual Workers and assign narrower Developer Platform roles, so teammates, CI tokens, and agents get only the access they need to debug, deploy, or monitor safely.
