Installation

Install and configure Miku Miku Beam on your system

Prerequisites

Before installing Miku Miku Beam, ensure you have the following tools installed:

Go

Version 1.21 or above

Node.js

Version 18 or above

npm

Node Package Manager

The project uses Go 1.24.5 in the source code. Any Go version 1.21+ should work, but newer versions are recommended.

Installation steps

1. Clone the repository

   Clone the Miku Miku Beam repository from GitHub:

   git clone https://github.com/sammwyy/mikumikubeam.git
   cd mikumikubeam
   
2. Install dependencies

   Use the Makefile to install both Go and Node.js dependencies:

   make prepare
   

   This command runs:

   • go mod tidy - Downloads all Go module dependencies
   • npm install - Installs Node.js packages for the web client

   If you encounter “module not found” errors, ensure you’re in the project root directory and have internet connectivity.

3. Create required data files

   Create the data directory and required configuration files:

   mkdir -p data
   touch data/proxies.txt
   touch data/uas.txt
   

   Proxies file (data/proxies.txt)

   Add one proxy per line in any of these formats:

   # With authentication
   http://user:[e-mail]:8080
   socks5://user:[e-mail]:1080
   
   # Without authentication
   http://proxy.example.com:8080
   socks5://proxy.example.com:1080
   
   # Shorthand (defaults to http protocol)
   proxy.example.com:8080
   
   # Port defaults to 8080 if omitted
   proxy.example.com
   

   If no proxies are configured, you must use the --no-proxy flag in CLI or set ALLOW_NO_PROXY=true for the server.

   User agents file (data/uas.txt)

   Add one user agent string per line:

   Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36
   Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36
   Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36
   
4. Build the project

   Build all components (web client, CLI, and server):

   make all
   

   This creates:

   • bin/mmb-cli - Command-line interface binary
   • bin/mmb-server - Web server binary
   • bin/web-client/ - Built React frontend

   You can build individual components using make cli, make server, or make webclient.

Configuration (optional)

Miku Miku Beam uses sensible defaults but can be customized with a TOML configuration file.

Default configuration

# data/config.toml
proxies_file = "data/proxies.txt"
user_agents_file = "data/uas.txt"
server_port = 3000
allowed_origin = "http://localhost:5173"

Configuration options

Option	Default	Description
proxies_file	data/proxies.txt	Path to proxies list
user_agents_file	data/uas.txt	Path to user agents list
server_port	3000	Web server port
allowed_origin	http://localhost:5173	CORS allowed origin

Using a config file

# CLI with custom config
./bin/mmb-cli --config data/config.toml attack http_flood http://example.com

# Server with custom config
./bin/mmb-server --config data/config.toml

Verify installation

Verify that everything is installed correctly:

CLI version

./bin/mmb-cli --help

You should see:

• Help output from CLI and server binaries
• Three items in bin/: mmb-cli, mmb-server, and web-client/

Makefile commands reference

The project includes helpful Makefile commands:

make prepare      # Install all dependencies (go mod tidy + npm install)
make all          # Build everything (web client + CLI + server)
make webclient    # Build React frontend only
make cli          # Build CLI binary only
make server       # Build server binary only
make run-cli      # Run CLI with example attack
make run-server   # Run web server
make clean        # Clean build artifacts

Troubleshooting

”concurrently” error on startup

This is a Node.js/React issue. Ensure you have Node.js v18+ installed and run:

cd web-client
npm install
cd ..
make webclient

Build fails with “module not found”

Run make prepare to download all dependencies:

make prepare

Web client doesn’t load

Make sure you’ve built the web client before starting the server:

make webclient
make run-server
