What is the product
Hyggshi OS Web Edition is a simulation operating system (OS simulator) that runs entirely in the browser, built with pure HTML/CSS/JavaScript, requiring no installation or additional building — just open the link and you can use it.

Problem solved
The product allows users to experience what it feels like to use a real operating system (desktop interface, terminal, file management...) without the need for a virtual machine or installing real Linux, making it suitable for demos, learning, or simply for entertainment.

Main features

• 9-step welcome wizard on first boot
• Virtual file system (VFS) simulating file/folder operations
• Window manager with multiple application windows
• Custom terminal (nexrun) along with a simulated package manager
• Multiple simulated desktop environments: Default, XFCE, GNOME, KDE
• Unique easter egg: typing rm -rf /* will trigger a series of "kernel panic" events → GRUB rescue → reinstall wizard

Who should use it
Suitable for those who love Linux/operating systems wanting a quick experience without installation, students/learners wanting to get familiar with the command line interface and desktop environment, or anyone curious wanting to "play" with a simulated OS right in the browser.

How to get started
Just access the product link using any modern browser (Chrome, Edge, Firefox...) on your computer — no installation required, no account needed.

What sets it apart
Unlike other OS simulators that usually only offer a static interface, Hyggshi OS Web Edition has a truly interactive terminal, a VFS that simulates file system logic, and a series of intricately designed easter eggs — creating a sense closer to that of a real operating system than just a simple UI demo. The product is also part of the larger Hyggshi OS (HORT) ecosystem including Linux distros, IDEs, custom programming languages...
