About Echo

Echo is a simple GTK app that pings a website or host from a graphical window, so you can check reachability without opening a terminal.

It is distributed through Flathub. On some systems ping permissions are restricted, and the project documents a sysctl change that allows unprivileged users to send pings.

Strengths

Graphical ping without the terminal
Lightweight and single-purpose

Limitations

May need a system setting changed to allow pings
Only does ping, no traceroute or port checks
