MoonOS Preview v1: Just the Beginning
Hey everyone, I’m launching MoonOS—a web-based operating system that runs entirely in your browser and adapts to whatever hardware you’re using.
Here’s the thing: it detects your CPU, RAM, GPU, and battery, then automatically adjusts its visual fidelity. Got a powerful machine? Full glassmorphism and particle effects. On a budget laptop? It strips down gracefully. No configuration. It just works.
You get a real window manager with drag, resize, snap-to-edges, virtual workspaces, a Spotlight-style launcher, a command palette, and keyboard shortcuts that feel native. There’s persistent storage with IndexedDB, so files you create actually stick around. Nine built-in apps: Terminal with a real filesystem, Notes with markdown preview, Files browser, Tasks, Calendar, Settings, Task Manager, Theme Editor, and a Browser.
The tech is intentional—Vite, React 19, TypeScript strict mode, TailwindCSS, Zustand, all bundled at just 137KB gzipped. Tested with Vitest and Playwright.
But here’s what matters most: this is v1, and I’m just getting started. I’m going to make this beautiful. Every detail, every interaction, every visual is going to be refined. MoonOS is going to look and feel incredible.
