Paperboy is a production-grade application for scheduling reports. It has a flexible architecture and extensible APIs, and can integrate into a wide variety of deployments. It is composed of various industrial-strength technologies from the open source world.

- [Jupyter Notebooks](https://jupyter.org/documentation) for the reports themselves
    - Jupyter notebooks are an ideal report template, and with [NBConvert](https://github.com/jupyter/nbconvert) support a wide variety of output types, including PDFs, HTML, Emails, etc
- [Papermill](https://github.com/nteract/papermill) to parameterize notebooks
- [SQLAlchemy](https://www.sqlalchemy.org) for Storage (default)
- [Apache Airflow](https://airflow.apache.org) for Scheduling (default)
    - [Dask](https://dask.org) for [Airflow Workers](https://airflow.readthedocs.io/en/stable/howto/executor/use-dask.html)
    - [Luigi](https://luigi.readthedocs.io/en/stable/) as a scheduling alternative for `Airflow` (relies on `cron`) 
- [PhosphorJS](https://phosphorjs.github.io) for the frontend
- Support for Python [Virtualenvs](https://virtualenv.pypa.io/en/stable/) via `requirements.txt` or custom [Docker](https://www.docker.com) images via `Dockerfile`s on a per-notebook level
- Traitlets parameterization of storage and scheduler classes for easy integration with custom storage backends and custom schedulers
- Single click notebook deployment with [Voila](https://github.com/QuantStack/voila) and [Dokku](https://github.com/dokku/dokku)
