Mac OS Monterey Web is an open-source Preact-based template that replicates the macOS Monterey desktop experience in the browser using standard web technologies like HTML, CSS, and JavaScript.
What is Mac OS Monterey Web?
Mac OS Monterey Web is an open-source project that recreates the macOS Monterey desktop interface as a web application. It renders a dock, menu bar, windows, and icons in the browser, built entirely with HTML, CSS, and JavaScript. The project is authored by PuruVJ and lives on GitHub at the macos-web repository. A live demo is hosted at macos.now.sh. This page documents the legacy version; the project has since been rewritten in Svelte and relocated to PuruVJ/macos-web.
What makes Mac OS Monterey Web stand out?
- Preact framework with performance focus — The project originally used React and was swapped to Preact for runtime performance gains, as stated in the readme.
- Vite bundler — Development and builds are powered by Vite, described as "super fast development" in the project's own words.
- Custom styling pipeline — Uses SCSS and CSS Modules for styling, with no component library, meaning every visual element is hand-coded.
- TypeScript typing — The GitHub topics list TypeScript, so the codebase is type-safe.
- Fully open source — The source code is available for inspection, and the project invites users to open issues and submit pull requests.
- Web-based accessibility — Since it runs on HTML/CSS/JS, the desktop can be accessed from any modern browser without installing software.
Who should use Mac OS Monterey Web?
- Front-end developers who want to examine a complex, real-world implementation of a desktop UI using Preact and CSS Modules, and who might contribute bug fixes or improvements.
- UI/UX designers who want an interactive, browser-based mockup of the macOS Monterey interface for demos or usability testing.
- macOS enthusiasts who don't own a Mac but want to experience a faithful recreation of the Monterey desktop in their browser.
What can you do with Mac OS Monterey Web?
- Customize a desktop shell: Developers can adapt the code to build their own web-based desktop with custom apps, using the existing dock and window manager as a foundation.
- Prototype macOS interactions: Designers can use the interactive UI to test how users react to macOS-like navigation patterns before building a native app.
- Learn modern front-end architecture: Students and developers can study how a large application is organized with Preact components, SCSS, and CSS Modules, with the roadmap and source code available as learning material.
