very excited to have the @deno_land team and @rough__sea join cloudflare! 🧡 workers and deno have been on a parallel journey over the past (nearly) decade or so in improving the fate of javascript on the server side. we have so so much respect for what the deno team has built and have drawn much inspiration from each other over the years!) one of the big gaps and criticisms of workers over the years has been that it's a platform that locks you in. many people still don't realize that workerd (the workers runtime) is open-source, but that's likely because realistically self hosting it, especially with durable objects has remained cumbersome that's what's been exciting to us about celld! thrilled to welcome the team and get started on making self-hosting workers apps a first-class experience!

it's decision model season 🍂 today, we open sourced clef and clef-flash, our first homegrown models — both now available on @cloudflare workers ai! demo / leaderboard: blog:

open source is core to so much cloudflare does today is the first day of @cloudflare birthday week, so here are a bunch of big updates to open source projects we maintain + some new ones: 1. we introduced forge — a new, free, OSS pipeline for auto generating SDKs, CLIs, docs, and libraries 2. cf cli — forge is in production and cloudflare is the first customer! our CLI now supports so much more than just workers 3. vinext 1.0 — what started out as a slopfork is now powering many organizations' production next.js apps 4. emdash 1.0 — the open source CMS that runs our blog (that we operate our network for) 5. 4 months of voidzero, speeding up the dev (and agent) toolchain — oxc compiles react.js 10x faster, vitest 5 is up to 50% faster, tsgolint is now stable (and up to 18x faster than eslint) and more!! 6. experimental preview of native rust in cloudflare workers! 7. big update to kitesurf — our open source agentic browser that runs on workers. webmcp and all 8. BEACON — open dataset of web performance data for you and your agents to go play with and explore forever blown away for how much cloudflare can ship in one day? as if we didn't ship a bunch of major announcements last week and have a whole week ahead still...

oh and btw this year's @cloudflare connect lineup is stacked. just a handful from the many i'm hyped for: @eastdakota & @zatlyn - @cloudflare @drfeifei - cofounder & CEO @theworldlabs @AdamMGrant - author & org psychologist @Wharton @saranormous - founder, @conviction @steipete - created of openclaw, @OpenAI @QuinnyPig - cofounder duckbill @evanyou, @tannerlinsley, @FredKSchott → web framework trifecta!! @FabianHedin - cofounder @lovable @_dylanga - @tryramp @KentonVarda @threepointone @dillon_mulroy - more good @cloudflare content this is going to be very fun

You can now run @OpenAI Agents API environments on @Cloudflare Sandboxes! Getting a Codex agent harness, available from the same API & SDK you're already using is just 👌 *And* it integrates with the rest of the Cloudflare ecosystem, check out @Jilles' demo 👇

I submitted my talk for Cloudflare Connect but it got declined. This would have been my card though... pretty cool. Come to Connect in SF October 19-21 to listen and talk with the people & companies building the Internet at a ridiculously fast pace.

Opening the Cloudflare dashboard feels like a hardware store. Everything looks useful. Easy to pick a product first and invent a problem for it. I start with a real problem, then use the smallest piece that removes it.

ICYMI, we enabled node modules by default for workers back in august. no more esoteric errors when using packages or frameworks, just good ol' node API support but here's more! today we introduce the new_module_registry flag, giving you access to:

in many ways, workers started out as its own little startup within @cloudflare. it was very fun to get to sit down with @jlengstorf (on a lamborghini in miami no less) and tell that story! and of course, i wasn’t alone on that journey — @KentonVarda’s vision, rethinking compute in the cloud was what started it all. and @dok2001’s leadership in ETI helped us stay on the right track and make sure we stayed customer focused, doing things that didn’t scale until… they did! honestly many companies would have killed the project or tried to find a shortcut to success and abandoned it in favor of short term revenue. of course @eastdakota being a student of disruption and clay christensen has given workers the runway to meet the moment that’s happening today with agents (and wildly enough predicted that it would take 10 years, which it did, almost on the dot!) please watch and thanks @clerk @jlengstorf for having me!

inspired by this I photographed our book towers and had Astra build a 3D model that allows me to pull (and find!) any book. now I’m wondering if I can create an AR app w/ part number overlays for my car…

walked past a chinese restaurant in paris before and they had ravioli on the menu so i thought it was like a chinese buffet we serve everything kinda place then i walked past a lot of chinese places, all of them serving ravioli and realized that’s what they call dumplings

there aren’t enough CPUs to power all the agents, which means sandbox architecture requires a rethink (isolates!!!) watch my investor day talk (apologies in advance for making you go to linkedin but that’s the best link i got):
