Create and deploy multi-page web app prototypes using chat
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…
In plain words
GPT Engineer is a web development tool that allows users to create and deploy multi-page web applications using plain English instructions through chat. The platform is designed for both technical and non-technical users to collaborate, with changes tracked as git commits. It uses large language models to quickly generate initial prototypes of a few hundred lines of code, which developers can then refine and extend. The tool targets teams looking to accelerate early-stage web app prototyping and iteration.

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 made as git commits, so that non-technical people (via chat) and programmers are able to contribute to the same code. LLMs are expensive, but we left it open over the christmas holidays for anyone to try it out: https://run.gptengineer.app/ Would love to hear what you think!

- CAClaude Artifacts but creating real web apps2024 · gptengineer.app · ▲189
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…

Hello Hacker News community, Wanted to share a project I started working on during my spare time and was then discovered by many in the open source community last week. GPT Engineer’s mission: Be the open platform for devs to tinker with and build their personal code-generation toolbox. I believe it's key for us devs to engage in how building software can and will change. You can find more info about the flexible technical "philosophy" to make it work well, and the community we want it to become on github: https://github.com/AntonOsika/gpt-engineer The project is still in…

Hi HN! I’m proud to share that we have built a real 3rd party iMessage client for Android. We did it by reverse engineering the iMessage protocol and encryption system. It's available to download today (no waitlist): https://play.google.com/store/apps/details?id=com.beeper.ima and there's a technical writeup here: https://blog.beeper.com/p/how-beeper-mini-works. Unlike every other attempt to build an iMessage app for Android (including our first gen app), Beeper Mini does not use a Mac server relay in the cloud. The app connects directly to Apple…

Hey! I made Heynote entirely for my own use case. For many years, I always had an Emacs instance running with the scratch buffer open, even long after I had abandoned Emacs as my programming editor in favor of more recent IDE:s. The simplicity of having just one big scratch buffer appeals to me, but I still want to separate the different things I jot down somehow (without using tabs or similar). Previously, my solution was to insert a bunch of blank lines between the notes, but hitting C-A would still select the entire buffer. That's why I came up with the concept of "blocks", which turned…
