The BeeWare suite of projects was not pulled out of thin air. There are a number of projects we use as a basis, and we are humbled to be able to perch atop the shoulders of these giants.
CookieCutter
CookieCutter is a command-line utility that creates projects from cookiecutters (project templates), e.g. creating a Python package project from a Python package project template.
Chaquopy
Chaquopy is a Python SDK for Android that offers integration with the standard Gradle build system for Android Studio, simple APIs for interoperability with Java/Kotlin, and a variety of third-party Python packages. It is used as the foundation for BeeWare's tooling on Android.
Lektor
This website has been created using Lektor, a flexible and powerful static content management system for building complex and beautiful websites out of flat files — for people who do not want to make a compromise between a CMS and a static blog engine.
octohatrack
All contributions count, not just code. octohatrack allows you to see all the contributors to a GitHub repo, not just the ones GitHub says are 'contributors'. Also available in a shiny website.
