    Hello, I'm working on a web browser that focuses on being truly lightweight and designed for privacy. At some point I've realized that much of the complexity and resource requirements of web browsers comes from JavaScript. This is because every part needs to be dynamic and optimized for speed. So a few years ago I've started to work on a web browser that intentionally doesn't implement JavaScript, instead it contains an updated set of scripts that fix and improve various websites. I've been using this approach using a proxy server for a few years as my primary way of web browsing with good…

    Hey HN, We got tired of browser frameworks restricting the LLM, so we removed the framework and gave the LLM maximum freedom to do whatever it's trained on. We gave the harness the ability to self correct and add new tools if the LLM wants (is pre-trained on) that. Our Browser Use library is tens of thousands of lines of deterministic heuristics wrapping Chrome (CDP websocket). Element extractors, click helpers, target managemenet (SUPER painful), watchdogs (crash handling, file downloads, alerts), cross origin iframes (if you want to click on an element you have to switch the target first,…

    Hi HN, I'm excited to share my open source project, a browser orchestrator. It's purpose is to make it easy to manage many browser profiles on one system. Currently it only works on MacOS, but since I've built it using Tauri (which is a Rust backend and TypeScript frontend), I expect to add Linux and Windows support in the future. I've built it primarily for myself as I use a lot of browsers and having an easy way to manage all of my profiles would make (have made, actually) my dock less cluttered haha. Also, part of why I built it is because as someone who doesn't really care about…

    Hello HN! I'm the creator and solo developer of Extension.js, a development tool for browser extensions with built-in support for TypeScript, WebAssembly, React, and modern JavaScript. Developers use it to spend less time configuring the compilation config or learning new frameworks and more time actually writing code. Most projects similar to Extension.js rely on some sort of abstraction or configuration to get started, making the initial development process slow given the extra learning curve and setup guidelines. By using Extension.js, adding the package to your npm scripts is all it…

    Hey HN, I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling. It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools. Hasn't this been done a lot of times? Good question, as a general…

    (spoiler: its XSLT) I've been working on a little demo for how to avoid copy-pasting header/footer boilerplate on a simple static webpage. My goal is to approximate the experience of Jekyll/Hugo but eliminate the need for a build step before publishing. This demo shows how to get basic templating features with XSL so you could write a blog post which looks like My Article some content hello hello Some properties which set this approach apart from other methods: - no build step (no need to setup Jekyll on the client or configure Github/Gitlab actions) - works on any webserver…

    Hey HN, we're excited to have people try out our framework! When we built out a Chrome extension earlier this year, we noticed that the config was too imperative. You had to constantly tell Chrome via the manifest.json file where your files were, what your permissions should be, etc. So we thought it might be interesting to build a more declarative framework. When we built a proof of concept, we enjoyed working with it and decided to invest more time into making it usable and adding more features. We're still pretty early in building it out, and there's a bunch more we want to add, but this…

    I built a web-based app for building websites. The main unique features are: 1. The ability to copy and paste any HTML and CSS into the editor with no limits. I was never able to find another app that could do this without some form of limitation. 2. CSS filtering, which means you can click on an element to view and edit the CSS selectors and rules that apply to that element alone. In many cases I've found CSS naming conventions like BEM to become irritating at certain scales, so this is an alternative solution. This part of the app needs some more development work but the concept is there.…
