Products that do what React.js LLM Agent (open-source) does

I've been working in the couple of months on an experiment, trying to make GPT-4 much more useful for web development / React, writing production code that is relevant to any repository without copy pasta from ChatGPT or having small snippets of auto-complete from Copilot that are not in your context. The agent is taking a user story text and generating and composing multiple react components to generate the relevant screens, based on atomic design principles, with Typescript, TailwindCSS and RadixUI. Is is still experimental but very interesting results, I would like to get your…

    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…

    We've just released the first version of GPT React Designer. A live editor that can generate React components. Copy and pasting code before you see how it would look is tedious. The goal is to extend this into an app that supports different styling frameworks (Chakra, Bootstrap, ...). Potentially integrate it directly into a codebase to perform tasks and so on and allow non-developers to simply utilize this to copy & paste code.

    Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

    I wrote a small "game" to showcase concurrent agents (via a library) working in a React app. It demonstrates how a React program can be written with DOD-inspired pattern to make it easy to reason about, straightforward in re-render instruction semantic. Thus as the side effect the program is performant. You're invited to view the source to examine the neat design pattern underneath as well as the agent management library that powers the app. Caveat: it doesn't work well in mobile yet, so switch to desktop site mode.

    Hey HN! I built Experiment to solve a common frustration in LLM development: the lack of proper tools for prompt engineering experimentation. Here's what makes it different: Key Features: - Load and edit chat completion logs from CSV files - Fork and modify specific conversation entries - Run inference via Anthropic, Mistral, and OpenAI - Define custom tools using JSONSchema format - Visual tool usage analysis with collapsible, sorted key-value pairs - Full mobile support and available as installable PWA Technical Highlights: - Built with React using custom isomorphic architecture -…

    I built Cossistant as a lightweight, open-source alternative to Intercom/Zendesk for NextJS/React devs. You can embed it with a simple NPM command and under 10 lines of code. The goal was so far to be a very very good human to human support platform, the next goal is to enable AI agents to auto-handle 80% of queries (train on your docs and knowledge) and eventually escalate to humans when needed. Everything is customizable with Tailwind or your custom React components. Support tools are bloated, pricey and never FEEL / LOOK like your product, this is why it's being shipped as…

    Hi! My name is David and I wanted to show you a react (and solidjs) library I've built over the last months. The intention behind it is, that there are some actually useful use cases for AI on the frontend that are largely unexploited still. LLMs are particularly good at extracting structured information from unstructured text and thats really useful for any types of forms - which can be multimodal. Setting up server side logic for AI usage can take time. Streaming data to the frontend and parsing it there to make it usable can be frustrating. Imho thats one of the reasons why people…

    Howdy friends! Tell me if this is an atrociously terrible idea - I've been working on building a leetcode for clientside devs so we can practice React and Javascript interview questions in a more concise way, I call it clientside.dev I just finished a beta version of it yesterday and plan on releasing it with many more problems on Jan 1st but it's there if you wanna play with it open to any ideas / feedback however mean or nice it may be :)

    A few weekends ago I was bored looking for a small project. I decided to make a small chat app that supports SSL and can be deployed easily. Front-end: ReactJS, Redux, Websockets Back End: Node.JS, Redis, Websockets Here is the source: http://www.github.com/lgse/react-chat Here is a demo: http://chat.lgse.net username: pick whatever you like! server: chat.lgse.net:1337 encryption: SSL/TLS There are still a lot of todos, but very functional for a small weekend project. Comments welcomed!

    Hi HN, Added a raw 45-second demo showing the DOM re-architecture in real-time: https:&#x2F;&#x2F;streamable.com&#x2F;vw133i I got tired of the "Context Problem" with static portfolios—Recruiters want a resume, Founders want a pitch deck, and Engineers want to see architecture. Instead of building three sites, I hooked up my React frontend to Llama-3 (via Groq for <100ms latency). It analyzes natural language intent from the search bar and physically re-architects the Component Tree to prioritize the most relevant modules using Framer Motion. The hardest part was stabilizing the Cumulative…

    Hi HF, I'm Terrell, and we built an open-source app that lets developers create their own Operator with a Next.js&#x2F;React front-end and a flask back-end. The purpose is to simplify spinning up virtual desktops (Xfce, VNC) and automate desktop-based interactions using computer use models like OpenAI’s There are already various cool tools out there that allow you to build your own operator-like experience but they usually only automate web browser actions, or aren’t open sourced&#x2F;cost a lot to get started. Spongecake allows you to automate desktop-based interactions, and is fully open…
