  • typer

    Typer, build great CLIs. Easy to code. Based on Python type hints.

    • Typer (https://typer.tiangolo.com/) builds on top of click I think. It is by the FastAPI folk as far as I know. Super easy and worth checking out if you don't know it.

  • docopt

    This project is no longer maintained. Please see https://github.com/jazzband/docopt-ng

    • I am a strong proponent of the philosophy behind http://docopt.org/ . Build the API for your humans, and then let the code come second.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
