But non-paid plan currently disables "Search engine indexing" of that sharing, so it's useless. There's an "Allow duplicate as template" button though which is nice.

URLs are horrendous however, e.g.: lofty-flower-be4.notion.site/aa-2274c59a06124d5b974b781a67340670 Only the aa in that came from us. They don't even have the guts for a fixed subdomain.

Also it does not work without JavaScript, no SSR, everything is dynamic.

They don't show multiple input pages on the same render, e.g.: lofty-flower-be4.notion.site/aa-2274c59a06124d5b974b781a67340670 does not contain the child lofty-flower-be4.notion.site/bb-45df7212a2e14e04b3f9604035c7acf4 as already implemented on OurBigBook Web Dynamic Article Tree.

Cross page links to work fine. But you don't link to explicit IDs, only internal hidden IDs. This can be even slightly confusing to users as multiple identical options can show up when you start creating a link. They do try to disambiguate with the parent page however.

So this is a reasonable single-person publishing platform for your notes.

Someone made and sold a helper for it:
