Im not familiar with rclone. Similar to syncthing?
Discussion
rclone is a mature command line program that supports over 70 cloud storage providers. Runs on Linux, Windows and Mac OS.
I use it for backup purposes, but this also makes the vault data available to my phone via Cryptomator app access to Onedrive (or Google Drive).
Note I have only tested unidirectional sync. That is, as I push from my laptop to cloud, the vaults are accessible on my Android phone, but I never push changes from my phone back to the laptop. rclone would be able to handle it, I just don't do it due to concern on the Cryptomator conflict resolution handling it properly.
In case I do want to push from phone to laptop, I have a dedicated "From_Mobile" vault for that.
