Building on Ilya Saunkin's answer, here's a command that should output your IP address formatted as a hyperlink - just substitute 3000 for whatever your port number is:
ifconfig | grep "inet " | grep -v 127.0.0.1 | sed 's/netmask.*//g' | sed 's/inet//g' | awk '{print "http://"$1":3000/"}'
Depending on where you're running the command, you should be able to (on a Mac) hold the command key and click/double-click to open the links.
