Getting started

Prebuilt binaries for Linux, Windows and OS X can be found on the release page.


Below are the available command-line options. Note that when running without any command-line switch (ie from a file browser), a launcher window will spawn to help setting them.

Preferences are stored in the user's home folder in a file named .open-stage-control (hidden under Linux / macOS)

Option Description
-s --send default targets for all widgets (ip:port pairs)
-l --load session file to load
--state state file to load (osc messages will be sent, unless there are other clients connected)
-b --blank load a blank session and start the editor
-c --custom-module custom module file to load
-p --port http port of the server (default to 8080)
-o --osc-port osc input port (default to --port)
--tcp-port tcp server input port
--tcp-targets tcp servers to connect to (ip:port pairs), does not susbtitute for --send
-m --midi midi router settings
-d --debug log received osc messages in the console
-n --no-gui disable default gui
-g --gui-only app server's url. If true, local port (--port) is used
-t --theme theme name or path (mutliple values allowed) see theming
-e --examples list examples instead of recent sessions
--url-options url options (opt=value pairs)
--disable-vsync disable gui's vertical synchronization
--disable-gpu disable hardware acceleration
--read-only disable session editing and session history changes
--instance-name used to differenciate multiple instances in a zeroconf network
--fullscreen launch the default client gui in fullscreen mode (F11 to exit)

Command-line only :

Option Description
-h --help print available options
-v --version print version number


open-stage-control --send --port 7777

This will create an app listening on port 7777 for synchronization messages, and sending its widgets state changes to ports 5555 and 6666.

open-stage-control --no-gui --load path/to/session.js --port 9999

This will create a headless app available through http on port 9999 with session.js loaded automatically.

What about HTTPS ?

Security is out of the app's scope. If you are concerned about safety, using a private - protected - network should be enough.

Run from sources

Running the app from the sources slightly differs from using built binaries : we'll build and launch the app with npm (node package manager).

1. Requirements

2. Download sources

git clone
cd open-stage-control/
# uncomment next line if you want the latest release
# instead of the current development version
# git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
npm install
npm run build

Updating from sources

git pull
npm install
npm run build

3. Run !

npm start [ -- options]

A double hyphen (--) is used here to tell npm that the options are to be passed to the app.

Build from sources

1. Requirements

2. Download sources & build package

git clone
cd open-stage-control/
# uncomment next line if you want the latest release
# instead of the current development version
# git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
npm install

# TARGET_PLATFORM can be linux, win32 (windows) or darwin (os x)
# TARGET_ARCH can be ia32, x64 or armv7l

npm run package

# For raspberry-pi / armv7l, run this instead
npm run package-rpi

# Do one of the following if you want a deb package for debian/ubuntu
npm run deb32
npm run deb64
npm run debarm

This will build the app in dist/open-stage-control-PLATFORM-ARCH.

Building the app for windows from a linux system requires wine to be installed.*

Running in a headless context

Electron, Open Stage Control's engine, is based on chromium and can't run out of the box without a display server. However, using a virtual framebuffer does the trick. Detailed instructions can be found in Electron's documentation.

In short: install xvfb and prepend your command with xvfb-run:

xvfb-run open-stage-control -n

Running without Electron

It is possible to run the server in headless mode without Electron using node (v6 or higher) :

node /path/to/packaged/open-stage-control/resources/app/ -n
node /path/to/sources/open-stage-control/app/ -n
