vimwiki is pretty good, but it uses a proprietary vimwiki format. You can switch it over to Markdown but you lose a couple features IIRC. I have a pretty extensive vimwiki, but it's only available on my laptops. I sync it via Git and have to remember to commit and push or it won't be available on another device. I did hack up a simple React/Go app a while back to give it a web interface with a simple WYSIWYG editor I could access from my phone, with auto-commit/auto-push, but I ultimately haven't really used it.
