Traffic Cop limits how fast each app may download and upload, and shows how much each one is using, including UDP (video calls). Useful on slow or metered connections: keep a video call usable while updates download, or stop one app from using the whole connection.
Apps are recognised by their systemd unit, which snap and flatpak apps always have; desktop apps get one when the desktop launches them in their own scope (GNOME does). Limits are applied with nftables and tc (CAKE).
After installing, connect the interfaces the background service needs:
sudo snap connect wasta-traffic-cop:network-control sudo snap connect wasta-traffic-cop:firewall-control sudo snap connect wasta-traffic-cop:system-observe sudo snap restart wasta-traffic-cop.daemon
Then open Traffic Cop from the menu, or in a terminal:
wasta-traffic-cop status what's limited and running wasta-traffic-cop rates -w live rates wasta-traffic-cop pause|resume turn the limits off and on
Administrators (members of sudo, admin or wheel) can change the apps and their limits; everyone can watch.

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 Traffic Cop, simply use the following command:
sudo snap install wasta-traffic-cop --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
