Need help: accessing all my containers by name

I’m to the point now where my little home device has enough services and such that bookmarking them all as http://nas-address:port is annoying me. I’ve got 3 docker stacks going on (I think) and 2 networks on my Synology. What’s the best or easiest way to be able to reach them by e.g. http://pi-hole and such?

I’m running all on a Synology 920+ behind a modem/router from my ISP so everything is on 192.168.1.0/24 subnet, and I’ve got Tailscale on it with it as an exit node if that helps.
