history
Project history and usage
Nyx is the Tor Project's command-line monitor for Tor relays. It gives relay operators a curses interface for bandwidth, connections, logs, Tor configuration, torrc inspection, and controller access through Stem.
Project history
Nyx is the renamed and redesigned successor to arm, the older command-line Tor monitor by Damian Johnson. The Tor Project blog post published on 2017-11-08 introduced Nyx as an overhaul of arm, highlighting Python 3 support, startup bandwidth graph improvements, IPv6 connection support, and connection viewing without toggling DisableDebuggerAttachment.
Adoption history
Nyx's adoption is tied to Tor relay operation rather than general shell use. The project page says version 2.1.0 was released on 2019-01-12, and package metadata shows it distributed through Homebrew plus Linux distributions including Alpine, Debian, Fedora, Arch, Ubuntu, and Nix. Homebrew reported 401 installs over the 365-day analytics window queried on 2026-07-01.
How it is used
Users install Nyx on the machine running Tor, enable a Tor ControlPort such as 9051 with cookie authentication, and run nyx in a terminal or SSH session. It is especially useful for relay operators who want top-like live status without a graphical desktop.
Why package nerds care
Nyx is significant because it is specialized operational tooling for a privacy network. Packaging it correctly matters: it depends on Python and Stem, needs terminal/curses behavior to work over SSH, and is part of the practical toolbox for people running Tor infrastructure.
