Is there anything like that?
How hard would it be to extend joplin to write a service driver to sync via Git(-hub / -lab / your own server)?
After trying out multiple note taking apps this is what I settled on. You can use it as simple as a note taking app or configure it to do lots of complicated things like managing your to-dos, appointments, agendas. And my favorite feature is inline code-block that I can execute.
I spent years in the same position we've all been in, searching and hoping for the perfect note taking app to boost my productivity, have a "second brain", write down my fleeting inspirations, etc. etc.
After finding Emacs last year, I feel like I've been under a spell my whole professional life that's been broken. I'm a little embarrassed of the time I've spent griping and pining for the perfect note app. It took me far less time to learn Emacs than it did to try out the 20+ todo and notebook apps on the market.
To all who are still on the hunt: there is no perfect app, and we're all kidding ourselves. You're looking for someone to give you a fish. This is just text we're talking about, it's easy enough to learn to wield it, manipulate it, and organize it, and soon you become the man who has been taught to fish on his own. Plus, when you have the epiphany of how much more quickly you can manipulate text with the control of Emacs and/or Vim, you'll wonder how you spent so much of your life in typing in software without these capabilities.
Learning Emacs has been one of the most rewarding experiences of my computing journey, I highly recommend checking out a well-configured distribution like Spacemacs.
I'm using clients for Mac, Android and linux (manjaro) and all work well. There are also clients for the other major platforms.
One of the things I really like about it is I can do a screenshot on both Mac & linux, saving to the clipboard rather than a file, and paste it directly into an editor and inkdrop handles everything, including creating a file and corresponding markup. And that all syncs too.

Basically, you have your notes in a git repo, and this app keeps committing the changes to your remote repo.
If you feel adventurous, you can try it here: https://github.com/tanin47/git-notes (still in early alpha)
This might not be an ideal solution, but if you find an editor you really like, its an easy way to add git and backup to your notes.
