crazy to see whos actually using MCP and my baby never thought id see fortune 500s on it now testing with them the newer version powered by @CloudflareDev 🧡 any names look familiar 😉?

@fashiongiik @Lovable let's gooooo, use fractal!!!

Apps inside ChatGPT are the way to get your business discovered by 900M+ people using it, but building them is still too hard. So we built Fractal: @Lovable for ChatGPT Apps It’s the fastest way for business owners, with or without a technical team, to ship exceptional ChatGPT apps

@kentcdodds @ctatedev Looked at the code, but its more of a library that can easily be added to a MCP Apps compliant server I think at a minimum, we can expose a template / resource to take in the tool input to generate these on demand from what the AI sends it given the catalog

Looks awesome! Is this built with the MCP Apps spec? In ChatGPT at least it seems that your MCP server needs to list out available templates (resources) at connection time (so you can't generate those on demand). Do you have a generic shell template and then the tool accepts the json which is passed to that app?

Introducing Generative UI for MCP Apps One server. Infinite interfaces. Instead of building views, define a component catalog. The AI assembles the right UI based on your API, CLI or MCP server tools. Works in Claude, ChatGPT, VS Code, Cursor and more

@dsp_ so clean, just bringing in any components into ur catalog and Claude or any AI just builds it with the components

That’s very cool

@thsottiaux too genius

Yesterday we launched subagents in Codex. Today we released GPT-5.4-Mini, which is SoTA in its category. Coincidence or genius move?

@rauchg yeah been exploring this so much with Generative UI, did some research at schools, and just with the UI + response, it went from "yeah im used reading chat essays" to "wait it can do that now!? i need this" its definitely a nice addition in terms of UX for some ppl

Every month I periodically see the recycled take that “something better than chat” is coming for AI. That chat is temporary. In fact, I predict the opposite. More of our work and life will happen through chat and voice interfaces of increasingly intelligent agents. 🦞 OpenClaw is the lobster in the coal mine of this. It’s true that as humans we consume with all the senses. When we use our internal company agent at @vercel, it can answer any question in English, but also plot data and richly visualize it. All in the chat medium. You start with any question, and receive periodic reports, much like an enterprise claw, on @slackhq. If the chat is not enough, you’re one click away from more depth and refinement on a web page. I don’t believe web pages are going anywhere. Many will evolve to accept natural language, which is the lingua franca of AI, and stream both text and complex data. We call this Generative UI (eg: json-render.dev). And web pages will also be crucial in enriching the conversations that happen elsewhere, whether you’re chatting with your agent on WhatsApp or Slack. We’re building chat-sdk.dev to make this universal interface as easy to deploy as possible.

@gdb been trying, it's too delish

gpt-5.4 has ramped faster than any other model we've launched in the API: within a week of launch, 5T tokens per day, handling more volume than our entire API one year ago, and reaching an annualized run rate of $1B in net-new revenue. it's a good model, try it out!

@shawnbuilds I'm coming 🫡

Hey everyone! We're excited to announce the Vancouver hackathon, “Build Canada 🇨🇦”. Join us with founders, developers, operators, and curious builders for a day of creating and shipping ideas, not just talking about them. Here are the details: When: March 22, 2026 (Sunday)   Where: Vancouver, BC   Who: Builders from across the city   Prizes: $1000 Cursor Credits Let’s get together, build something cool, and show it off!  Hope to see you there!

@dok2001 @threepointone he the kinggggg

. @threepointone is a class act and a pretty cool guy.

no hate please, lets have peace in world

@youyuxi @wesbos makes total sense, been building with cloudflare + @RedwoodJS so completely understand how DX here is so good even with the lock in

@wesbos x.com/youyuxi/status…

Vite just announced the Laravel/Rails for JavaScript DB, auth, KV, queues, storage, ai ++ React/Vue/Svelte/Solid and Integrates with existing metaframeworks as it's just a Vite plugin The more interesting part is they are launching their own framework with it which feels a lot like tanstack start. Has routing/loaders/actions/islands/ISR and is inspired by Inertia.js By default it's tightly bound to Cloudflare workers — which is where all the bindings come from — and will include deploying without a cloudflare account Uses better auth and drizzle under the hood

@thsottiaux literally everything I'm doing 🤭

It will all come together and it will be beautiful

@Infoxicador ayyy this is so beautiful, MCP Apps make it so easy to build the experiences

This is an MCP App This is a native capability of Claude. They could have custom built it into, but decided not to. It proves the MCP Apps architecture is so solid that you can also use it in your own 1st Party UI

@coreyching it's beautiful

Codex themes are live. 🎨 Productivity gains: TBD. Vibes gains: immediate.

@tokifyi I'm down, need to meet other lowkeyz

hey founders & builders! after months of building solo, i’m hosting a lowkey builder happy hour in vancouver + drinks, stories, real human connection (something ai can’t do) no pitches, no panels, just builders hanging out irl spots are tiny, reply/dm if you want to join and i’ll send you the rsvp form

@ZeffMax what if it was spatial coding x.com/i/status/20314…

New: OpenAI saw the AI coding revolution coming years ago, but was beat to market by Anthropic. This is how OpenAI got in this position, and how a small Codex team spent the last year racing to build a billion-dollar competitor to Claude Code. (yes Codex now has >$1B in ARR)

@whoiskatrin @garrytan ☝️this

@garrytan just use code mode blog.cloudflare.com/code-mode-mcp/

MCP sucks honestly It eats too much context window and you have to toggle it on and off and the auth sucks I got sick of Claude in Chrome via MCP and vibe coded a CLI wrapper for Playwright tonight in 30 minutes only for my team to tell me Vercel already did it lmao But it worked 100x better and was like 100LOC as a CLI

@stuffyokodraws raw text file 😂😅 but definitely agree, we need a good solution for this

Someone needs to build a better vault for agents. 1Password could work, but the setup experience for using the CLI and the constant need to re-auth with the most expensive tool call -- asking a human, is not agent friendly at all.

@appfactory Loving this journey boss. Totally agree with the Developer Cage and focusing on the "why" Congrats on the launch everyone, been having a blast using RedwoodSDK 🫡

RedwoodSDK v1.0 is released, and we're on HackerNews! Read about my journey here: rwsdk.com/blog/redwood-v…

@thedavidprice @RedwoodJS @mojombo @appfactory @cannikin Loving this, people coming together and saying "lets make it better", so freaking exciting Thank you team for starting this story Super happy on the 1.0 launch, will keep using and contributing 🥳

❤️ The journey of @RedwoodJS is the story of the people behind the project. Working at the beginning with @mojombo, @appfactory, and @cannikin is a personal life highlight. I couldn't be more excited and inspired by @appfactory as he leads the next chapter of the story. rwsdk.com/blog/redwood-v…

@karpathy how about spatial 🤯 x.com/gching/status/…

Expectation: the age of the IDE is over Reality: we’re going to need a bigger IDE (imo). It just looks very different because humans now move upwards and program at a higher level - the basic unit of interest is not one file but one agent. It’s still programming.
