OS.js is an open-source JavaScript web desktop platform with a window manager, application APIs, a GUI toolkit and filesystem abstractions. You can run the packaged distribution, or use the base repository as a template to build your own browser-based desktop OS.

Key Features

• Window manager — draggable, resizable and minimisable application windows in the browser.
• Application APIs — build and integrate in-browser apps with a documented framework and GUI toolkit.
• Filesystem abstractions — a virtual file system layer so apps can read and write consistently.
• Extensible base — the OS.js repository is a template for your own distributions and installations.
• Official Docker image — quick self-hosting with docker run osjs/osjs.
• Bundled applications — file manager, code editor, drawing tool, calculator, settings and a system tray.

Why Use OS.js?

OS.js gives developers and sysadmins a mature platform rather than a one-off toy. With its app framework, Docker image and long history, it is well suited to building a custom web desktop for internal tools or a product.

Use Cases

• Building a custom-branded web desktop for a SaaS product or internal portal.
• Housing multiple web apps inside one consistent browser environment.
• Learning how a full web desktop platform is architected.
