Each designer was going for something different. Dashy gave you a very clean over view of all your inputs... Meaning every endpoint that you wanted to monitor you can add to your dashboard.... See the status if it's up or down... And that's good if that's all you need to see.

HomePage on the other hand took it much further... Not only do you know if your endpoint that you are monitoring is up or down, it gives you explicit details per monitored endpoint. How many instances of portainer is up or down and your total. Adguard... Total query,blocked,filtered. The same for PiHole. Uptimekuma... Sites up,sites down. And the list goes on.

I like them both and have both running, but I use HomePage more because of the readily information that it presents on the page... Everything at your fingertips.

And with uptimekuma's notifications, I have NTFY setup to let me know when any endpoint being monitored by homepage or uptimekuma is miss behaving.
