24 alternatives to React.js LLM Agent (open-source)
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…

I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

Locofy.ai▲720Hey there, I am Honey - Co-founder at Locofy. We, along with other makers, have been building Locofy.ai to help massively accelerate the builders - the designers, developers, product managers & founders, and we're excited to share it today with the HN Community. Locofy.ai simply converts designs into production-ready frontend code for web and mobile apps. It adapts to your preferred design tools, tech stack, and workflows with ease and lets you launch upto 4x faster, while letting designers design the way they want and giving high-quality responsive code that developers love. With this…

Hi HN, Yesterday I live streamed myself for 6 hours building this from scratch. It’s an AI agent that uses Llama 2 (so far the 13b chat model) to generate a full react codebase from a single prompt. It had a “dev loop” that iterates on your feedback and resolves dependencies. In the end it kinda worked and I got excited so wanted to post here haha. Long story short a viewer on my discord suggested I build in of these and I just had to look into how these work (inspired by GPT Engineer and AutoGPT) I wanted to work on a more specific downstream task so I focused on web dev. Llama 2 isn’t the…

Hey Hacker News! Launching gptengineer.app into beta today. It's like Claude Artifacts, but: - you can edit the code in your fav IDE (two-way github sync) - installs npm packages - automatically picks up build and runtime errors and fixes them - very fast, built with rust The full stack capabilities are built on supabase (prefer to not have to handle auth + user data at this point so this is owned by the user) The seed for this project was an open source experiment, posted about that previously here: https://news.ycombinator.com/item?id=36422730 Would love feedback if you give…

This started out as an experiment - we were interested if, given a short description in plain English, GPT can generate a functioning full-stack web app in React & Node.js.

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! I made a React compatibility library for a Virtual DOM library (https://github.com/aidenybai/million). The idea is to have much faster rendering (a compiler optimizes virtual DOM beforehand) while ensuring the same developer experience React provides. This is very, VERY early stage, so be prepared for weird bugs / plugin incompatibility / etc. If you have any suggestions, I'd be more than happy if you replied in a comment with it! You can spin up the demo here >> https://stackblitz.com/github/aidenybai/million-react-compat

Everyone's shipping AI tools right now, and here I am with a visual editor. Still, I think many teams are very familiar with the problem of "marketing wants to change the landing page again." I've run into this for years. Campaign pages come in, engineers get pulled in, and tickets stack up. It's usually the same components, just rearranged. A few years ago, at a startup I worked at, we built an internal tool to deal with this. You register your existing React components, they show up as drag-and-drop blocks, and the result is a JSX string. No schema to learn, no changes to your component…

I’m building an experimental tool that can generate a UI component from a high-level text description, i.e. “Design a card for viewing goals in a goal tracking application”. Basically, stable diffusion but for user interface components instead of images. This tool is at best a proof of concept. It currently only generates a single type of component (small cards that have basic info about an object), but the goal is to be able to design entire applications (either in one fell swoop or by piecing together components that the tool generates). The components it generates can be exported as react…

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…

Hello everyone, For the past several months, I have been building multiple React/TailwindCSS components for my projects. I have decided to bundle and document them so that I can share them with the community. The entire UI kit is written in Typescript on top of the class-variance-authority library. Although I am already using these components in production, the project is still in beta since it lacks a full test suite and dark mode. Please feel free to take a look and provide feedback if you have a moment to spare. Thank you!

gptengineer.app lets you prototype, deploy and iterate on web apps using plain english. Here is a video of how I use it: https://www.loom.com/share/abda1d8e33134d0e944297afd3a51664 We designed it around the principles: 1. Leverage LLMs where they work best: LLMs are faster than humans at putting together prototypes of a few hundred lines of code. By using them early on, and give high level change request commands when the project is small, and then let human devs take over, it’s a productivity boost. 2. non-technical + programmer collaboration: All changes from the app is…

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.
