blfp-client

Project Overview

BLFP Client is an all-in-one multiplayer client for Minecraft Java Edition. The host creates a room with one tap and gets a 6-digit room number; friends simply enter the number to join, with no public IP required. Game traffic travels over an EasyTier virtual network that tries P2P connections first and falls back to relay nodes, while an frp fixed relay serves as a backup channel.

Let friends join your Minecraft world quickly with a 6-digit room number, no public IP needed.

Key Features

• Smart networking: built on EasyTier, each room uses its own temporary credentials, tries P2P first and relays automatically on failure
• Node selection and speed test: specify an EasyTier node, or let auto mode pick the lowest-latency one
• frp relay mode: a backup option that forwards through a fixed public node with a random tunnel name and reports connection info
• Room number: the host gets a 6-digit room number on creation, and friends join with a single entry
• LAN discovery: scans open ports automatically and broadcasts the MOTD so the room is easy to find in game
• Members and status: shows the member list, latency and online count
• Update check: checks GitHub Releases for new versions

Target Audience

• Minecraft Java Edition players who want to play with friends but lack a public IP
• Users unfamiliar with port forwarding or NAT traversal configuration
• Players who need a desktop client on Windows or Linux

Quick Start

1. Download the package for your platform from the Releases page
2. Run the .exe installer on Windows, or use the AppImage or .deb package on Linux
3. The host creates a room and shares the 6-digit room number with friends
4. Friends enter the room number to join, then connect to the host's virtual address in Minecraft

Core Advantages

• No public IP needed: no port forwarding or public address required, lowering the barrier to playing together
• Dual channels: smart networking favors direct connections while the frp relay backs up connectivity
• Automatic node selection: auto mode picks a low-latency node, cutting manual tuning
• Transparent status: the member list and latency are visible at a glance to judge connection quality

System Requirements

Item	Requirement
OS	Windows, Linux
Architecture	Windows 64-bit; Linux x86_64 / amd64

Notes

• On Linux, EasyTier needs CAP_NET_ADMIN, so run as root or grant it with setcap
• Connection quality depends on your network; if a direct link fails, it switches to relay or frp automatically
• Only Minecraft Java Edition is supported
