Light the way for friends

Open your Minecraft world, share a code, and play together. No relays, just a clear path through your router.

What you’ll need

  • Windows 10/11, 64‑bit
  • 8 GB RAM recommended
  • Home router with UPnP/NAT-PMP/PCP or IPv6 (else manual forward)

Tip: You can use our built‑in server or your own Paper/Spigot install.

Live compatibility demo

We’ll check your OS, CPU bitness, memory estimate, API reachability, IPv6, and a NAT guess (via WebRTC STUN). This runs in your browser; no installs.

Summary:
Note: NAT results are an approximation from the browser. UPnP/PCP and Windows Firewall can’t be tested here.

How it works

1) Start or pick a server

Use the built‑in Paper server or point to your own Paper/Spigot/Vanilla. We keep it private by default.

2) Open for friends

We try UPnP/PCP/NAT‑PMP or IPv6. If that fails, we show simple manual steps. No relays.

3) Share a code

Your friends enter a short code. We never publish lobbies. You stay in control.

FAQ

What if my router doesn’t support UPnP/PCP?

You can still host by setting a manual port forward (we provide step‑by‑step guidance) or using IPv6 if available.

Does this work if my ISP uses CGNAT?

Not without manual help from your ISP or native IPv6. We don’t relay game traffic.

Do my friends need Windows?

They can join from any Minecraft Java client once they have the address. The helper app (for join codes) is Windows‑first in v1.
