Conda-forge is a community-led collection of recipes, build infrastructure and distributions for the conda package manager. Our GitHub organization contains repositories of conda recipes. Thanks to some awesome continuous integration providers (AppVeyor, CircleCI and TravisCI), each repository, also known as a feedstock, automatically builds its own recipe in a clean and repeatable way on Windows, Linux and OSX.
Conda-forge is the preferred way to install large parts of the PyData and R ecosystem. It is used throughout a disparate set of scientific computing domains, from Physics to Biology to Financial Technology and everything in between.
