Ninode

A powerful terminal-based server monitoring application built with React 19 and OpenTUI

Ninode is a modern, lightweight terminal user interface (TUI) for monitoring and managing Linux-based remote servers via SSH. Monitor multiple servers simultaneously, track system metrics in real-time, manage processes, view logs, and set up custom alerts—all from a single, beautiful terminal interface.
