NEX OS comes pre-loaded with more than 25 built-in applications, ranging from system utilities and developer tools to multimedia players and productivity suites. Every application runs inside its own draggable, resizable window managed by WindowManagerContext — the central kernel of the OS. Each app is a self-contained React component rendered inside the Window Higher-Order Component, which provides drag, resize, snap layouts, minimize, maximize, and z-index management without any app needing to implement those behaviors itself.

​
App Categories

File Explorer

Navigate the Virtual File System with tree and list views, drag-and-drop, breadcrumb paths, and .nex executable launching.

Terminal & CMD

Two terminal emulators — Windows CMD-style (Cmd.tsx) and Bash-style (Terminal.tsx) — with npm, pnpm, and .nex runtime support.

Task Manager

Real-time CPU and memory monitoring powered by a WebAssembly engine written in AssemblyScript and Rust, delivering near-native performance.

NEX Browser

NexBrowser Pro: an integrated multi-tab browser with YouTube playback, per-tab history, bookmarks, and private mode.

Productivity Apps

Notepad 2.0, Paint, Photos gallery, Calculator, Calendar, Clock, WordPad, VS Code clone, Dev-C++ 2026, SpotifyMini, and more.

App Isolation Model

Each NEX OS application operates in its own React component scope. No application accesses another app’s state directly — communication happens exclusively through the shared context layer (WindowManagerContext, FileSystemContext, SettingsContext). This mirrors the micro-frontend architecture pattern: every app is independently mountable, and the Window HOC wraps each one to provide system-level capabilities. 
// Every app is opened through WindowManager — never rendered directly
const { openWindow } = useWindowManager();

openWindow(
  'notepad',             // Unique window ID
  'notepad',             // App type (appId)
  'Notepad 2.0',         // Window title
  <Document24Regular />  // Window icon
);
When a window is minimized and later restored via restoreWindow(), the app’s internal React state is preserved — the component is never unmounted and re-mounted.

​
Registering New Applications

All taskbar and start menu applications are declared in src/constants/apps.tsx. To add a new app to NEX OS:
1

Create the component

Add your new app file to src/components/apps/MyApp.tsx and export a default React component.
2

Import in the registry

Open src/constants/apps.tsx and import your component at the top.
3

Register the app entry

Add an entry to the APPS array with a unique id, an icon, a display label, and the component factory:
import MyApp from '../components/apps/MyApp';
import { Star24Regular } from '@fluentui/react-icons';

{ id: 'my-app', icon: <Star24Regular />, label: 'My App', component: () => <MyApp /> }
4

(Optional) Add to Start Menu

For the app to appear in the Start Menu, also add an entry to StartMenu.tsx.
You can also expose your app as a .nex executable in the Virtual File System by adding a VirtualFile with ext: 'nex' and a nexPayload object pointing to your app’s registered id. Users can then double-click it in File Explorer or run it from the terminal.
