Simple, powerful, and efficient live streaming software built on Electron and OBS.
This application currently only supports 64-bit Windows.
Node is required for installing npm packages and for running various scripts. We recommend the current LTS release, 8.x.x:
In order to ensure you are using the correct version of each node module, you should use the yarn package manager. Installation instructions can be found here:
Visual C++ Compiler
Yarn will install and compile a number of native extensions from source. For yarn to do this, it needs a Visual C++ compiler. The most reliable way to get this is to install:
Visual Studio Community 2015 with Update 3
Make sure you do a custom installation and select Visual C++ from the languages section.
Some of our native addons require CMake for compilation. You can download it here:
Make sure to add CMake to your path. You may have to restart your machine before CMake is available.
Node-gyp requires python 2.7 available in your path to install some native addons. You can download it here:
Install all node modules via yarn:
Install OBS plugins:
Then, compile assets with webpack:
If you are using Visual Studio Code, you can start the app using the built in debugger (default F5).
Otherwise, you can run the app with:
These variables can be used in development to force certain behavior.
SLOBS_FORCE_AUTO_UPDATE: Force the auto-updater to run in development. Normally
this would only run in production.
SLOBS_CACHE_DIR: Force a different location for the user data cache directory.
SLOBS_REPORT_TO_SENTRY: Report errors to sentry in the dev environment
Packaging / Distributing

should make sure that node-obs is compiled correctly with 32-bit
and 64-bit plugins, and works properly with the currently checked
out version of
streamlabs-obs. If you're releasing, that should
probably be the
master branch. You should probably try running
the app from your dev environment to make sure everything is
working before you start the release process.
Make sure the app is not running in your dev environment before you start the packaging process.
You can package the app by running:
This will package a distributable installer
.exe to the
directory. There is also an unpacked version in
