Introducing oniux:

A small command-line utility providing Tor network isolation for third-party applications using Linux namespaces. Built on Arti, and onionmasq, oniux drop-ships any Linux program into its own network namespace to route it through Tor and strips away the potential for data leaks. If your work, activism, or research demands rock-solid traffic isolation, oniux delivers it.
