Welcome to gwf

gwf is a flexible, pragmatic workflow tool for building and running large, scientific workflows. It runs on Python 3.5+ and is developed at the Bioinformatics Research Centre (BiRC), Aarhus University.


To get a feeling for what a gwf workflow looks like, have a look at a few examples.

Getting started

To quickly get started writing workflows in gwf you can read the Tutorial.


We don’t have the backend you need to run your workflow on your cluster? See the Writing Backends section to roll your own.


We aim to make gwf a community developed project. Learn how to contribute.
