Game Server Hosting

Host Minecraft, Valheim, Terraria, and Factorio game servers from your PC. Let friends join without port forwarding or renting a server.

Want to play Minecraft with friends but don't want to rent a server or fight with port forwarding? Localport creates a public address for your local game server in one command. Share the address, and friends connect directly.

How it works

Most game servers use TCP. Localport gives your server a public address with a dedicated port. Share that address with your friends and they join as if you were running a public server.

Minecraft (Java Edition)

The most popular use case. Here's the full setup:

1. Start your Minecraft server (default port 25565)

2. Open a second terminal and run:

localport tcp 25565 --token YOUR_TOKEN

3. You'll see:

tcp → tcp://abc123.tunnel.localport.dev:47266

4. Send your friends: abc123.tunnel.localport.dev:47266

5. They go to Multiplayer → Add Server → paste the address → Join

That's it. No router config, no firewall rules.

Bedrock Edition

Minecraft Bedrock uses UDP on port 19132. Localport currently tunnels TCP traffic, so Bedrock isn't directly supported. Java Edition (which uses TCP) works perfectly.

Valheim

localport tcp 2456 --token YOUR_TOKEN

Share the address with friends. They join through the server browser or direct connect.

Terraria

localport tcp 7777 --token YOUR_TOKEN

Factorio

localport tcp 34197 --token YOUR_TOKEN

Things to know

  • Latency is minimal — Localport adds single-digit milliseconds. For most games, you won't notice.
  • Reserved ports (any plan) — Keep the same address across sessions so friends don't need a new one every time.
  • Uptime — The tunnel is active as long as the CLI is running. Close the terminal or shut down your PC and the tunnel closes.
  • Works behind any network — University dorms, corporate WiFi, CGNAT, mobile hotspots. If you can browse the web, Localport works.

Tip for regular game nights

Reserve a port so your server always gets the same address. Save it as a server in your friends' game clients once, and it works every time.
