WinBox is a lightweight HTML5 window manager for web applications. Developers can create movable desktop-style windows, control their title, position, size, color, and behavior, and fill them with HTML or mounted DOM content. It is available through npm, bundled files, or separate JavaScript and CSS assets, with community wrappers for frameworks such as Vue and React. Any user-controlled HTML must be sanitized before insertion, because passing it directly into a window can introduce cross-site scripting vulnerabilities.

React NodeGUI is a React renderer for NodeGUI that builds Qt5-based desktop applications for Windows, macOS, and Linux. Developers can compose native widgets with React, style them with cascading CSS and Flexbox, and use Node.js APIs without bundling a Chromium runtime. The repository explicitly states that the project is no longer maintained, so adopting it now means accepting an aging stack or maintaining a fork yourself.

Tauri Controls supplies minimize, maximize, and close controls styled for Windows, macOS, or GNOME in Tauri 2 desktop applications. It can detect the current operating system automatically or let developers select a platform style, with packages for React, Solid, Vue, and Svelte projects. Window actions are handled through Tauri’s JavaScript and TypeScript APIs. The controls are HTML elements designed to resemble native system components rather than wrappers around native UI APIs, and integration requires the corresponding Tauri window and OS plugins plus peer dependencies.

Add-to-Homescreen is a drop-in JavaScript library that shows platform-specific instructions for installing a website or PWA on iOS, Android, Windows, or macOS home screens. It supports more than twenty languages and can redirect users from several in-app browsers to the system browser. The site must already meet basic PWA requirements, including an app icon and web manifest.
