Domphy – plain-object UI for tool apps, AI-correctable output
I built a UI framework named Domphy because I could not learn React although I tried many times. I mean I could not understand React code which is hidden behind multiple layers, especially when some of them use React ecosystem libs. Maybe I am an architect turned developer, so I had no foundation of programming, or I expected something clear and clean. I just think that UI should be simple — HTML and JS are enough and just need some way to make it stateful instead of making it more complicated. My idea: just using JS objects to reflect HTML, and using functions for state. When I need to…
In plain words
Domphy is a UI framework that uses plain JavaScript objects to represent HTML, paired with functions for state management. Designed for developers who find React's complexity overwhelming, it eliminates deep component nesting by using "patches" to add properties to base objects. The framework keeps interfaces simple by building directly on HTML and JavaScript, avoiding multiple abstraction layers while maintaining stateful functionality.

I built a UI framework named Domphy because I could not learn React although I tried many times. I mean I could not understand React code which is hidden behind multiple layers, especially when some of them use React ecosystem libs. Maybe I am an architect turned developer, so I had no foundation of programming, or I expected something clear and clean. I just think that UI should be simple — HTML and JS are enough and just need some way to make it stateful instead of making it more complicated. My idea: just using JS objects to reflect HTML, and using functions for state. When I need to reuse a component I had one more concept — just make a partial (I call it a Patch) to add props to the main object (but native props still win). With a component-based approach you get deep nesting and exploding props, but with patches you don't. The example below: import { ElementNode, toState } from "@domphy/core"; import { tooltip } from "@domphy/ui"; const count = toState(0); const App = { div: [ { h3: (listener) => `Count: ${count.get(listener)}` }, { button: "Increment", onClick: () => count.set(count.get() + 1), $: [tooltip({ content: "Add one to the count" })], }, ], style: { display: "flex", gap: "8px", alignItems: "center" }, }; const root = new ElementNode(App); root.render(document.getElementById("app")!); Right now I am the only one using Domphy, for around a year, for creating SketchUp and Revit plugins in the AEC (Architecture, Engineering, Construction) industry. I created Domphy before AI code generation took off, to make code humans can read and understand clearly, but now AI can build UIs with React well, so sometimes I feel my work is meaningless. But I still use Domphy for my apps, because I feel more confident when I need to read and edit UI code when the AI gets stuck.

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.

Hey HN, Henry from Cactus here! We previously released Cactus Needle, a 14MB agentic LLM for tool call, device use, and structured extraction for phones, wearables, smart homes, small robots and microcontrollers. We got really great feedback here, and have now incorporated the suggestions to release Needle 2. The whole model is a single 14MB binary that runs a full session in 28MB of RAM; 45m parameters at 2bit compression. Needle hits 500 tokens/sec decode speed on a Raspberry Pi 5, sits between 400-1,500 tokens/sec on VR devices like Meta Quest 3S and Apple Vision Pro, and ranges…

- H6Homebrew 6.0.0▲1,481
Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
