1.4.0 — optional cloud-folder backups
Released on latest/stable · revision 6 · November 7, 2026. Operoso 1.4.0 is the current stable release, available from the Snap Store. This is the same package accepted with an existing Google-synced folder and released to beta on November 5, promoted without rebuilding.
The working database stays local. Your sync client handles cloud upload: a local save does not confirm remote upload. No backups run while Operoso is closed. Copies are not encrypted by Operoso. This is backup, not simultaneous multi-device editing. Read the cloud-backup guide.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install Operoso, simply use the following command:
sudo snap install operoso
Browse and find snaps from the convenience of your desktop using the snap store snap.
