Clairic is a new model from Cloudflare that is a System One extraction modeI, capable of extracting, computing, estimating, and forecasting data from unstructured inputs.

So a good while ago I added a fun curl version of my site, meant for viewing in the terminal. Try running these commands! (sorry Windows users, not my fault that ANSI escape codes are disabled-by-default in cmd.exe. And not my fault that in Powershell you have to use curl.exe ins

Putting ourselves in the best place to build the future of the web

I asked two agents to collaborate to defuse a bomb. Agent A could observe the bomb's display and cut wires; agent B could interpret the contents of the display to determine which wires needed to be cut. Cutting the wrong wire caused an explosion. Thus the two agents needed each o

We’re announcing the closed beta of a self-serve Cloudflare OHTTP Gateway. We’re also renaming our Privacy Gateway to Cloudflare OHTTP Relay to better distinguish the two products.

God damn it, we're back in the room again. Yes, that sound in your ears is screaming. The footgun has gone off again, shockingly, and we are yet again dealing with a situation where the entire world apparently knew about Citrix NetScaler CVEs before Citrix had woken up or

We are releasing cf, our new command-line tool that mirrors the entire Cloudflare API and supports programmatic TypeScript configuration. We are also open-sourcing Forge, our internal SDK generator.

You've probably heard me complain about the "AI crawlers" before, but now I actually have some hard numbers I can put up to show their im...

Machines are now the majority of consumers of web content. AI agents will soon be the largest consumers of search. Agents need search because the information required to complete real tasks is often too fresh (”Who won the Dodgers game yesterday”) or too niche (”Can the same GM s

Thomas Sauvin’s archive of discarded family negatives captures an era when 36 photos could document years of birthdays, travel, and everyday life.

Hosting Git repositories at scale is a nightmare. When Linus Torvalds designed the first version of the information manager from hell (that's actually the tagline for Git, look it up), he had a very specific use case in mind: his own. He wanted to replace BitKeeper, the distribut

I recently started thinking about VCRs, as you do. I'll spare you the train of thought that led me to this, but it started with a conversation about worsening eyesight and then it escalated from there. Anyway, VCRs. I still remember the first VCR my dad bought when I was a kid. A

Andrew Oram asked why programming languages rise and fall, and quoted the answer without noticing. Programming is a vocation, an art, and a job. Make any of those harder than they need to be, and your language survives exactly as long as it can't be replaced.

Cloudflare is shifting bot mitigation from point-in-time Risk assessment to continuous Trust evaluation. Learn how new good and bad behaviors from bots and agents are assessed by our systems, including BotBase and Precursor — and try out our Precursor Trace simulation to see how

Blitz is currently in a pre-alpha state. It already has a very capable renderer, but there are also still many bugs and missing features. We are actively working on bringing it into a usable state but we would not yet recommend building apps with it. Check out the roadmap issue f

One of my personal philosophies is that one’s personal site should feel like a digital home. As someone who stops to enjoy the light a lot, I felt it was very important that my digital home have nice lighting too.

November 2014 It struck me recently how few of the most successful people I know are mean. There are exceptions, but remarkably few. Meanness isn't rare. In fact, one of the things the internet has shown us is how mean people can be. A few decades ago, only famous people and prof

I propose an approach for highly personalized LLMs, for near-future productivity gains and personal info/cybersecurity against increasingly powerful LLMs: they should, in the spirit of uploading, try to emulate the user’s values and preferences in order to amplify the principal—n

Watch dictionary compression in action. JavaScript bundles compressed at the edge by Cloudflare using RFC 9842.

Today, we’re excited to give you a sneak peek of our support for shared compression dictionaries, show you how it improves page load times, and reveal when you’ll be able to try the beta yourself.

Metrics don't just measure encoder performance; decoding matters too, and even after decoding, not all post-processing is created equal.

Agents can write code faster than we can absorb it. Here's why it still matters for humans to understand what they build — and some techniques for doing that efficiently: explainer docs, quizzes, micro-worlds, and shared spaces.

Quattron is the brand name of an LCD color display technology produced by Sharp Electronics. In addition to the standard RGB (red, green, and blue) color subpixels, the technology utilizes a yellow fourth color subpixel (RGBY) which Sharp claims increases the range of displayable

Precursor, our new continuous behavioral validation engine for bot management, offers visibility into how humans and bots actually interact across the full user journey. By turning session-level behavior into bot detection signals, it identifies advanced automation with higher pr

The most practical way to measure quality is to test with many different people, and have many experts take a look. If thorough testing and 100 experts can’t find a problem, the thing is probably perfect. Perfection is impossible. The agreed-upon best-designed software in the ind

Essay I of Upstream of Everything

I am a software engineer, and I used to enjoy arguing with people for technical correctness. Code reviews, design meetings, mailing-list threads, dinner tables. If someone was wrong, I wanted them to know it, and I wanted them to know exactly why. I collected counterarguments the
