I'm sharing this because I think the idea is great and can also be leveraged to launch environments of other languages. From the article:
"When you use wp-now from a directory, we create a php-wasm instance, download the selected WordPress version and mount the necessary directories in a virtual file system (VFS). Then, we initiate a NodeJS express server that listens and proxies all requests to the php-wasm. As a result, wp-now can easily log you into WordPress automatically, activate plugins and themes, and automatically configure your WordPress site."
