Play with friends on a "server" that's really your own machine — with NAT traversal handled for you — and keep your favorite servers one click away on the home screen.
Opening a Minecraft server to friends normally means port forwarding, static IPs, or renting a host. XMlauncher's P2P mode tunnels friends straight to your world using UPnP automatic port mapping with a relay fallback when your router refuses — you just host, they just join.
The home screen keeps a live list of servers you can join in one click — no copy-pasting IPs. Pinned favorites surface first, and the list refreshes so entries are current, not stale.
When this feature detects the problem, these are the actions it can apply for you.
