System requirements

newsic's backend is based on Python 3 and the Flask framework, while the frontend uses Plyr (which comes bundled with this repository). Required Python packages are listed in the requirements.txt.

Optional dependencies

Starting with version 0.3 newsic offers support for caching, compressing and minifying - based on Flask Caching, Flask-Compress and htmlmin. The packages are installable with pip install -r requirements-performance.txt. See config.py.example for all available options and module documentation.

For using .env and .flaskenv newsic supports python-dotenv. Installable with pip install -r requirements-env.txt or, more directly: pip install python-dotenv.


  1. Clone this repository: git clone https://github.com/newsic/newsic.git
  2. Go to newsic/newsic and create a config.py from config.py.example
  3. Add your API keys (YouTube, Vimeo) to config.py
  4. Install the minimal requirements with pip install -r requirements.txt; you might want to use a virtual environment
  5. Set newsic as Flask app with export FLASK_APP=newsic and start it with flask run. The script is now running at


For running newsic on your server (or a shared hosting provider) you would like to use a deployment script. There are many different options for running Flask on a server.

As an example have a look at the FCGI script powering the newsic demo (hosted proudly on Uberspace) in the deployment repository.
