I thought many times about building this kind of self-hosting note taking app, but what's stopping me is that it's not very useful without all the mobile and desktop clients, and that's very hard to develop. That's probably the reason why there's currently no good open source solution for this.

tagSpaces does a fairly decent job of it. its only missing a few hundred features compared to evernote but its mainly just one guy making it for the last few years so its fairly impressive at the same time. hopefully more features will be added eventually like a proper tagging system and stuff like note links, better search etc.
