It's in the article:

> HTTP also allows the DuckDB-Wasm distribution to speak Quack natively! So DuckDB running in a browser can e.g., directly connect to a DuckDB instance running in an EC2 server using Quack.

Although a maintainer answered you, watch the video from the blog. There's a WASM demo at the end, which is great. It also has a good explainer for those confused about the HTTP decision.

And I appreciate that the Hannes still appreciates the magic of the WASM. [And I keep hearing quark which makes me hungry for tangy creamy German yogurt]

Maintainer here. Yes!
