The best problem-solving writing in software engineering — databases, performance, security, frontend and distributed systems, in one feed.
Cloudflare just turned 15! Birthday Week 2025 celebrated innovation at scale: Rust-powered core systems, post-quantum upgrades, developer access for students, PlanetScale integration, open-source partnerships, and our biggest internship program ever — 1,111 interns in 2026.
Alignment might be one of the more confusing (or misunderstood) parts of CSS. I love having a thorough explanation from someone like Temani Afif who has it
Safari 26 adds:75 new features, 3 deprecations, and 171 other improvements. Here's all the CSS goodness you'll want to know about.

Imagine being able to use AI to create 3D virtual worlds using prompts as easily as you can generate images. The intersection of AI and VR was one of the biggest topics at Meta Connect this year. In his keynote, Mark Zuckerberg shared his vision of a future where anyone can create virtual worlds using […]
Over the past 21 years, Meta has grown exponentially from a small social network connecting a few thousand people in a handful of universities in the U.S. into several apps and novel hardware products that serve over 3.4 billion people throughout the world. Our infrastructure has evolved significantly over the years, growing from a […]
Today, we announced that Stripe is powering OpenAI’s new commerce experience, Instant Checkout in ChatGPT, and we released the Agentic Commerce Protocol, a new open standard that enables programmatic commerce flows between AI agents and businesses.
Claude Sonnet 4.5 is now available on Vercel AI Gateway and across the Vercel AI Cloud. Also introducing a new coding agent platform template.
Cloudflare is using its vast traffic to send responses faster than ever before, by learning the characteristics of each individual network and tuning our congestion control system.
We’ve replaced the original core system in Cloudflare with a new modular Rust-based proxy, replacing NGINX. It’s not only substantially faster for all our customers, it’s also more secure, and lets us ship new products quicker than ever before.
Cloudflare Radar offers two new features: regional Internet traffic visibility for a more local perspective on trends and disruptions, and a new dashboard bringing insights into Certificate Transparency, the ecosystem which ensures that all website certificates are publicly visible & auditable.
We reduced Cloudflare Workers cold starts by 10x by optimistically routing to servers with already-loaded Workers. Learn how we did it here.
Today, we’re announcing two enhancements to our Application Performance suite. Observatory and Smart Shield allow you to see how the world sees your website, and make it faster with one click. Available inside the Cloudflare Dashboard today!
Cloudflare will soon automatically create an AI-optimized search index for your domain, and expose a set of ready-to-use standard APIs and tools including an MCP server, LLMs.txt, and a search API. For AI builders, Cloudflare will offer a new way to discover and retrieve web content.
AS-SETs, for better or worse, are critical data sources that help build BGP route filters across the Internet. Because these AS-SET objects are based solely on trust, they can be misused. We will cover some of the reasons why operators need to monitor the AS-SET memberships for their ASN, and now Cloudflare Radar can help.
On the Internet, being fast is what matters and at Cloudflare, we are committed to being the fastest network in the world. In this post, we will share how our network performance has changed since our last post in September 2024, and discuss the tools and processes we are using to assess network performance.
It turns out we've all been using MCP wrong. Most agents today use MCP by exposing the "tools" directly to the LLM. We tried something different: Convert the MCP tools into a TypeScript API, and then ask an LLM to write code that calls that API. The results are striking.
John Rhea challenged himself to recreate the fancy button using the new CSS shape() function sprinkled with animation to get things pretty close.
This post demonstrates how to perform a point in time recovery(PITR) for a PostgreSQL cluster on cloud environment using CNPG
Why the U.S. Supreme Court case Cox v. Sony matters for developers and sharing updates to our Transparency Center and Acceptable Use Policies.
For this year’s Cybersecurity Awareness Month, GitHub’s Bug Bounty team is excited to offer some additional incentives to security researchers!
AI is everywhere and, as network engineers, we are right in the thick of it: building the network infrastructure for AI. This year, at our largest @Scale:Networking ever, engineers from Meta, ByteDance, Google, Microsoft, Oracle, AMD, Broadcom, Cisco, and NVIDIA came together to share our latest experiences in architecting, designing, operating, and debugging our AI […]
The protocol is the API.
What if your best AI prompts didn’t disappear into your unorganized chat history, but came back tomorrow as a reliable assistant? In this article, you’ll learn how to turn one-off “aha” prompts into reusable assistants that are tailored to your audience, grounded in your knowledge, and consistent every time, saving you (and your team) from typing the same 448-word prompt ever again.
