    Hey HN, I'm Nate, the creator of Tamagui. One is a React framework that does two things differently in hopes of simplifying how we build websites and apps: 1. It unifies React Native and React web with typed file system routing by making Vite able to serve RN. This lets you share (or diverge) your code in a simpler way for cross-platform apps. 2. We've partnered with Zero (https://zerosync.dev) to make local-first work well. We've been building a solution in One that makes Zero supporting server rendering, without waterfalls, and with seamless server/client handoff. ---…

    Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

    Hey HN. Eric Seidel here (former lead of Flutter & Dart at Google, prev. YC S06). I founded Flutter and led the team for almost a decade. One of the constant questions we got was would we support code push like the web/react native: https://github.com/flutter/flutter/issues/14330 I left Google about a year ago and set out to build a company around Flutter and decided to start with code push. It took us a year to build. We had to build a new toolchain for Dart and a custom interpreter (for store compliance). But it works! Our beta has already been used by…

    Hello HN! The day has finally come to stop adding features and start sharing what I've been building the last 5-6 months. It's a bit of CrewAI, OpenDevon, LangFuse/Cloud all in one, providing devs who prefer TypeScript an integrated framework thats provides a lot out of the box to start experimenting and building agents with. It started after peeking at the LangChain docs a few times and never liking the example code. I began experimenting with automating a simple Jira request from the engineering team to add an index to one of our Google Spanner databases (for context I'm the…

    Hey HN, I’m Kiet, and I’m one of the co-founders of Onlook – an open-sourced desktop app that lets you visually edit your locally running React app, then write your changes back to code in real time. I posted the repo a few months ago [1] when it was just 2 weeks old. Since then, we’ve made some big changes/improvements. I wanted to share some of the updates we’ve made and add more technical details. Here are the three big ones: • Inserting new elements - Draw elements in the live page like a design tool and write them back to code. • Component detection - Detect when an element is a…
