Apps is a progressive web app that aims to adhere to the App Shell model. The primary routes are prerendered as static HTML during the build process and are loaded lazily at runtime to ensure a smaller client-side JavaScript bundle. The source code is hosted on GitHub and comprises several components that operate within the Angular framework.

As an example, try the face-detector component below. It is built with TensorFlow.js using a WebAssembly backend. The blazeface model is used for face identification with a webcam or by dragging and dropping images into the drop zone (where the QR code is). All facial detection is completed client-side.
