Related update: organice just got comprehensive documentation (https://organice.200ok.ch/documentation.html).
Good job with organice! I have looked for such a project for quite some time. However, even if it looks great (and has mobile/web apps), it still misses one element from my flow: there is no git backend. Are there any plans to add it?
Thank you for your kind words 🙏
organice already features a huge amount of synchronization options: Dropbox, Google Drive, WebDAV (which opens the door to ownCloud, Nextcloud and Seafile, but also self hosted dedicated WebDAV servers like Apache or Nginx).
I’ll happily merge any PR enabling a different backend and support the development of it and will test it if I have access to a compatible backend.
As for me, I have no plans to build a Git client in the browser as this would be a huge undertaking with uncertain benefits. Personally, I’m happy synchronizing to storage like Dropbox wherein my Org files are sitting in a Git repository. Then, I can properly manage them from a proper Git client (in Emacs).
Got it, however, there are some existing Git clients for browser/node environment like Isomorphic-Git.  I’d be interested to add such to the organice, test it by dogfooding it. ;)
Regarding other features: I have reviewed the current capabilities and they represent very good coverage of my workflow. Almost fitting my sweet spot. ;) Additionally, I am a GSuite user, so GDrive fits perfectly. However, any Linux-based client for it is an abomination, mildly put (paid/free, doesn’t matter), and I do not have any incentive to use Dropbox.
From a quick glance, isomorphic-git looks nice! I’d be happy to support you if you have any questions whilst creating a PR for integration.
NB: I’ve heard people use GDrive as a back-end for NextCloud. I have no experience with that, but find the NextCloud Linux client itself quite good.
