Install mStream Binaries for Win/OSX/Linux

This is the easiest way to install mStream. They have no dependencies so you can just download and run them. These releases come with an additional set of UI tools and features:

Install mStream From The Command Line

If you just want the core part of mStream without all the UI tools, you can install mStream from the NPM or Git repositories.

# Install From NPM
npm install -g mstream
# Install From Git
git clone
cd mStream
npm install --only=production
sudo npm link 

Running & Configuring mStream

To test your installation, run the command mstream. This will boot an mStream server on port 3000 and will use the current working directory as your music directory. Command line flags can be used to test different mStream configurations

# change port (defaults to 3000)
mstream -p 4999

# setup user
# the login system will be disabled if these values are not set
mstream -u username -x password

# set music directory
# defaults to the current working directory if not set
mstream -m /path/to/music

## lastFM Scrobbling
mstream -l username -z password

Configure mStream with a JSON file

mStream can also be booted using a JSON file using the -j flag. Using a JSON config file allows for more advanced configuration options, such as multiple users and folders. When booting with a JSON config file, all other flags will be ignored. An example config with multiple users is shown below.

mstream -j /path/to/config.json
  "port": 3030,
  "folders": {
    "blues": "/path/to/blues",
    "metal": "/path/to/metal"
  "users": {
    "dan": {
      "vpaths": ["blues", "metal"]
    "james": {
      "vpaths": ["blues"],
      "lastfm-user": "username",
      "lastfm-password": "password"

Editing a JSON config by hand is tedious. There's a number of special flags that will launch a prompt to guide you through editing the config

# Set a blank config
mstream --init config.json
# Add Folder
mstream -j config.json --addpath /path/to/folder
# Add a User
mstream -j config.json --adduser
# Change the Port
mstream -j config.json --editport
# Generate a Secret
mstream -j config.json --makesecret
# Add SSL Key/Cert
mstream -j config.json --addkey <ssl key>
mstream -j config.json --addcert <ssl cert>

# Delete Users
mstream -j config.json --removeuser
# Remove Folders
mstream -j config.json --removepath

Android/iPhone Apps

mStream has an Android App in progress. The app is currently in the alpha stage of development, but it works well enough for public use. The app will be released to Google Play once it's no longer an alpha.

For now you can download it from the git repo


mStream uses a JSON based REST API. The API is documented here
