I use a directory structered with a wiki Dir, log Dir, a few others, in which markdown formatted notes are saved, as well as any other kind of file I want to save. You can use many tools to browse a filetree of markdown files, I use QOwnNotes on the desktop and Markor on Android. The Dir is synced, I use Resilio but many tools would do the job. This way I have a privately 'hosted' 'system' which is quite flexible in term of software and longevity; so many tools exist and are bound to exist to interoperate with this I do not worry about lockin or things like that. Been using this setup in various forms for nearly a decade, and I think at least a decade more.
