Yabs has currently beta status.

Yabs is a command line tool, that runs a sequence of tasks in order to test, build, and deliver a Python software project.



  • Define a custom workflow definition using YAML syntax.
  • Check preconditions to prevent unwanted or failing releases.
  • Run external tools like linters and check their return values.
  • Bump version number in Python or text files.
  • Create source and built distributions by running setup.py.
  • Tag, commit, and push to git repository.
  • Publish releases on PyPI or GitHub.
  • Comes with prebuilt activities, but can be extended by custom task-plugins.
  • This is a command line tool that runs on Linux, macOS, and Windows…
  • … and a library for use in custom Python projects.


Releases are hosted on PyPI and can be installed using pipenv (Python 3.6+ is required)

$ pipenv shell
