CodeSandbox

Browser-based development environment for React, Vue, Angular, and more. Instant previews, collaborative editing, deploy with one click. Ideal for prototyping and sharing demos. It boots a full npm dependency tree in the browser, so a shared link opens a running project rather than a snippet.

Progressive Web App

A demonstration progressive web app that shows core PWA capabilities working together: offline support, push notifications, background sync, a splash screen, and add-to-home-screen installation. Useful for developers who want to try these behaviors in a live app before implementing them in their own projects.

Serwist

A set of JavaScript libraries described as a Swiss Army knife for service workers, with this site hosting its documentation. Serwist helps web developers add precaching, runtime caching, and offline behavior to their sites, continuing the approach popularized by Google's Workbox.
