This isn't WebVM specifically, but one example using WebContainers we've built is https://demo.graphweaver.com/

This runs a NodeJS server and frontend in your browser so you can see what Graphweaver can do without having to install or run anything more than a browser on your computer. The example has an SQLite database joined to a REST API. Graphweaver serves a GraphQL API with the result.
