Decent tool, I've used it for a project before. You can connect a Notion page and publish it into a live website.

You can add custom separate pages, and do a good bit of customization, but overall you don't get that large a difference between just publishing a Notion page to the web.

It is cheaper to add a custom domain to Super sites though, as opposed to doing it directly through Notion's system.

So if you need a public website built off your Notion page with more customization and a cheaper custom domain, this is perfect.

Admittedly, though, that's a pretty niche situation.
