   Anytype - Public Beta▲907

   Anytype is built on the open-source AnySync protocol: a local-first protocol based on CRDTs. Users of Anytype can create spaces - graph-based databases with modular UI.

   Anything API▲656

   Hey HN! We built Notte, a browser infrastructure and agents platform. Many of our users automate UI workflows or extract data from sites that don’t have APIs. In practice, we noticed that once an agent understands how a site works, parts of the task can often run without a browser by interacting with the same network requests the site uses. So we built Anything API: describe a browser task, and our agent explores the site, builds a function, tests it against your description, and deploys a callable REST endpoint. No infra to manage. How the build works: - Describe the task (best results come…

   One – A new React framework unifying web, native and local-first▲506

   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. ---…

   Copy React code from any site▲374

   I made this because building React components from scratch is super annoying. Most visual elements already exist on the web, and I figured there should be a way to leverage that. I hope it's useful!

    Nub – A Bun-like all-in-one toolkit for Node.js▲277

    Colin here, creator of Nub. I’ve had the general shape of this in mind for years. Nub runs your code with stock `node`, augmented with a `--require` preload hook[0] that adds a transpiler (oxc-powered, packaged as a Node-API add-on), registers a module resolution hook[1], and injects polyfills as needed for APIs like `Worker`, `Temporal`, etc. All purely additive, your code ultimately runs using Node’s actual engine & stdlib implementations.

    I've been making JavaScript sandbox alone for 6 years▲397

    Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

    Chunk – Code sandbox for back-end devs▲96

    Chunk co-founder here. We spent the last 2 weeks building this to scratch our own itch: As developers, we often have problems that could be solved just by running a few lines of code. Sometimes, running this code on your local machine is fine. But other time, the code need to run automatically reacting to external events or to run continuously, which means, it needs to run on a server somewhere. So now, you have to find a cloud provider, to package or build the code and finally to deploy it. All of that for what could be literally be 4 lines of code. We couldn’t find an easier way to do…
