Terminal dashboard for ports, processes, and Docker containers

A terminal dashboard for ports, processes, and Docker containers.
Like htop but focused on network ports.

What is whosat?

whosat is a terminal-based system monitor that answers one question: "who's sitting on that port?"

It scans all listening ports on your machine, groups them by process, enriches them with CPU/memory stats, and displays everything in a rich interactive TUI. Think of it as htop meets netstat — you get a live, searchable, themeable dashboard showing every port, the process behind it, and what resources it's consuming.

Whether you're debugging a port conflict, hunting down a runaway process, or just want a quick overview of what's running on your system — whosat gives you the answer in one command.

Install

pip install whosat

With Docker support:

pip install 'whosat[docker]'

Usage

whosat

That's it. whosat will scan your system and display all listening ports and their processes.

• Port & Process Monitoring — See all listening ports with owning processes, CPU/memory usage, and uptime
• Memory View — System-wide process memory usage with GPU memory tracking (NVIDIA)
• Docker Integration — Optional container monitoring alongside system processes
• Group & Flat Views — Group processes by name or view as a flat list
• Detail Panel — Expand any process to see full network info, open ports, resource usage, and CPU sparkline
• Actions — Ping, curl, and kill processes directly from the TUI
• Live Refresh — Configurable auto-refresh (15s / 30s / 1m / 2m / off)
• Theming — 6 built-in themes (matrix, nord, dracula, tokyo-night, gruvbox, solarized)
