Deco.cx – realtime TypeScript web editor
Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years.

In plain words
Deco.cx is an open-source web editor designed for TypeScript developers, built on JSX, HTMX, TypeScript, Tailwind, and Deno. It provides a visual interface for editing and managing TypeScript-based websites in real time, allowing both developers and content creators to modify configuration and content through a collaborative admin UI. The tool functions as a git-based configuration management system, letting teams manage hundreds of enterprise-grade React websites without needing to write code for every change.

Hi, HN. Gui, Lucis, and the deco.cx team here — we're a bunch of Brazilians building an open-source, all-in-one web editor for the modern TypeScript dev. Check out our GitHub at https://github.com/deco-cx/deco and discover more at our site https://deco.cx/. We built frontend tools at a hyper-growth e-commerce platform for 9 years. Deco.cx is the thing that we wish existed when we were managing hundreds of enterprise-grade React-based websites. The gist is: JSX, HTMX, TypeScript, Tailwind and Deno. All visually editable in a beautiful, collaborative, REALTIME (!) admin UI. Great for devs, great for content. In essence, we're a git-based TypeScript-first configuration management system. We take TypeScript code that represents your site, your entities, your UI, and we allow anyone to "save" configuration and content based on those types. It's great for developers, because you can code directly on the web, or on your machine, and get instant feedback. You "export interface Props" and boom, an automatic form is generated. It's great for the business users, the content editors, because you just press "." (dot) in your keyboard and you go into a visual edit mode for the page you're at right now. Everything the developer exported in TypeScript is editable. And when you hit "publish", it's already live, with a proper CDN, proper caching, everything already setup and just working. Ready to scale! But you can't fly blind. We're democratizing pro-level tools for web analytics and observability by bundling in our Pro plan: fully-managed Plausible analytics and HyperDX observability. Check them out — these are great tools on their own, and they shine in the deco.cx platform bundle. We don't want to be the only answer, we don't claim to be right about anything, we just want to make the friendly and accessible open-source tool that we wish existed when we were junior developers. If you want to participate, please join our discord community at https://deco.cx/discord on open-source: our admin UI core is not ready for prime time, we're working to open-source it this year. but basically everything else, our integrations, templates and configuration management runtime are all open-source already! take a look at these: https://github.com/deco-cx/deco https://github.com/deco-cx/apps https://github.com/deco-sites/storefront Making the admin UI core extensible and open source is a MAIN OBJECTIVE for this year, so expect news here soon! Thanks for your support!
