It not only supports IPFS, it is "built on top of" it, according to the website.
This makes me wonder if it's usable for regular web browsing or only IPFS sites. The latter would sort of make it a splinternet browser, and way less interesting.
It's definitely the latter. The sites it renders are just markdown files stored on the IPFS network. I don't think it can render HTML let alone a modern web app on the internet
