Plus, trilium has a self-hostable sync/web server. The data is stored in a database but you have the option to export as markdown/HTML.

Only issue is that its maintained privately by one person. I take this as a plus but it does mean that theirs a bus factor of one (unless someone else forks it).

yup, there's a legit bus factor question, but it's not totally a one person's job either having a healthy stream of contributions (some even as code). What makes it even less a concern for me is that the scope of the software is clear and finite, its implementation mature with no major feature missing and it has a sound design. Boring is good in this area as far as I'm concerned.
