Imagine you never needed an app again. Every screen on your phone, generated live the moment you ask. No app store. No downloads. No predefined screens. You ask for dinner, and the screen to order it gets written - right then, just for you. We're calling it AppLess.

We built a better alternative to json-render & A2UI Up to 3x faster rendering & 67% fewer tokens. Far fewer broken outputs. We've been shipping Generative UI interfaces to 10,000+ developers for the past year. We know where JSON-based rendering breaks in production. So we built a new format - one that works with how models actually generate, not against it. And today we're open sourcing it: openui [dot] com

Today we're launching OpenUI Cloud We've spent months arguing AI deserves more than text. The uncomfortable truth is Generative UI in production needs much more than just rendering. The boring parts - validation, error correction, fallbacks, versioning, audit trails - eat up 80% of the time and become the critical factor in deciding whether your Generative UI agent reaches production or dies trying. OpenUI (open source) handles the rendering. OpenUI Cloud handles that 80% nobody should have to rebuild. > npx @openuidev/cli@latest create

Introducing Generative UI for Eve powered by OpenUI Building this was a real joy. Vercel has done a great job with Eve - minimal yet an elegant abstraction. I'm excited to see where it goes next but a simple filesystem based agent feels like right directionally

Replacing dashboards with a chatbar was step one Here's what step two could look like (Inspired by Basedash - they've been building in this space for a while)

Someone shared a fascinating visual of an AI agent moving through a real codebase - reviewing structures, making decisions, and committing changes. It’s a reminder that software development is quietly entering a new phase. Not automation in the traditional sense, but systems that can understand context, navigate complexity, and contribute meaningfully. We’re still early, but the trajectory is unmistakable: coding is becoming more collaborative between humans and intelligent agents than ever before.

We turned OpenClaw into a workspace A cron handles my morning brief from PostHog, GitHub, and Stripe That part's solved. But I'm obsessed with those metrics - which means I'm reprompting all day I just wanted one place to see them all I've been making the case all year that AI needs more than chat. Had to put our money where our mouth is. Built it for myself first. Now can't work without it. So we generalized it and shipped it as open source. This is what SaaS 2.0 should feel like

Love what Claude shipped with Cowork Artifacts but generating code for Generative UI is the wrong architecture Wasteful: A single dashboard costs 2k boilterplate React/HTML tokens before any meaningful pixel is streamed Inconsistent: Two dashboards generated 5 mins apart don't feel like the same product. No design system. No shared components. Every output is a one off Security Liability: Today its a single-user sandboxed demo. But real software has shared dashboards, team views, embedded reports - LLM generated code for one user running in another user's session. Sandboxed or not, that's OWASP LLM05 territory. Multi-surface: A dashboard generated for desktop never works reliably on mobile. Want to render it on an iPhone? Your only option is an iframe. Yuck. Unstreamable: Partial code is extremely hard to stream meaningfully. What you get is hundreds of chunks of broken renders that flash and flicker. That's not progressive UI - that's broken UX. Code generation is a great starting point. It's not a production architecture. Generative UI in production needs an abstraction layer. The model describes intent. The renderer owns the pixels. Everything else is a liability.
