Oniux: Kernel-level Tor isolation for any Linux app
Published on: 2025-06-11 16:46:50
When launching privacy-critical apps and services, developers want to make sure that every packet really only goes through Tor. One mistyped proxy setting–or a single system-call outside the SOCKS wrapper–and your data is suddenly on the line.
That's why today, we are excited to introduce 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.
What are Linux namespaces? 🐧
Namespaces are an isolation feature found in the Linux kernel that were introduced around the year 2000. They provide a secure way of isolating a certain part of an application from the rest of the system. Namespaces come in various forms and shapes. Some examples include network namespaces, mount
