## 1\. Web containers API

Stackbliz, an online IDE has introduced a WebAssembly-based OS which allows to run web runtimes on the fly on the browser.

Battle-tested (Sveltekit tutorial uses Webcontainers), this opens up opportunities to make highly interactive web tutorials using the API. Other use cases given on their site include AI applications to run OpenAI directly on the browser as well as No code platforms.

### Features

1. Inbroowser filesystem: An ephemeral filesystem to load files/dirs and do UNIX-like operations on them.
    
2. Node.js CLI on the browser
    
3. Dev server: Spin up HTTP servers on the browser which works even user looses internet connection thanks to virtualized TCP inside the browser's Service Worker
