GoKawiilRouler tool lets Windows users route each app's traffic through a different network interface
Rouler is a new Windows utility that allows users to assign individual applications, or specific IP addresses, to separate network interfaces at the same time. For example, a browser could use a privacy VPN, a work app could use a corporate tunnel, and other traffic could go through the normal connection simultaneously. The developer describes it as working purely at the network layer, distinct from a VPN or firewall.
