gotop

Another TUI graphical activity monitor, inspired by vtop and gtop, this time written in Go!
Built with gopsutil, drawille-go, and a heavily modified version of termui which uses termbox-go.

Installation

Go code compiles to a single executable so you just need to somehow get that into your $PATH.

Either manually download the latest release for your OS from the releases tab and move it into /bin, or run this command to do it for you:

sudo ...

If you install this way, starting gotop with the -u flag or pressing u in gotop will check to see if there is a newer version available and automatically update if so.

Windows is currently untested/unsupported but PR's for fixing that are welcome.

Arch Linux

Alternatively, if you're on Arch Linux you can install the gotop package from the AUR.
