Nextcloud is amazing, I just don't have the resources or time to self host right now so I'm currently not using it. Big problem for me is that most cloud providers don't actually support syncing to the filesystem through Android's Storage Access Framework and instead keep all of the data in the app data, requiring me to manually export from the cloud application, and re-import into the password manager.
That's amazing, I'm going to try it out since they added support for my current cloud provider at the start of this year. Another poster here has also talked about pass, which I'm going to try out too I knew it synced with Git, but I wasn't aware that the mobile applications available would do the sync through Git too.
