HeyPuter/puter ? reverse-engineered prompt

Build me a personal cloud computer that runs entirely in the web browser. It should feel like a complete desktop operating system where I can store all my files and apps and access them from anywhere. I want it to be a private, self-hostable alternative to services like Dropbox or Google Drive, but with a full graphical user interface.

The main idea is to have an open-source "internet OS" that I can run on my own server. It should be feature-rich and fast. The project is based on JavaScript. Let’s get it set up and running, maybe using Docker since that seems like a good way to self-host it. The goal is to have a working remote desktop environment that I can log into from any browser.
