A GNOME Shell extension with an indicator in the task bar displaying status of entered web server URLs using emojis:
initializing...
server down/unresponsive
malformed URL
server up and responding
The task bar shows the worst status from the set of all server statuses in the popup menu. Server down is considered worse than bad URL.
To customize, the four .svg files in the assets folder can be swapped out with your own icons. Just keep the same filenames.
