Reproducible Science Made Easy: Package Management with Pixi
Reproducibility is a major underpinning of the scientific method. In scientific computing, this also includes the ability to reproduce your dependencies. Yet, in 2025 this still remains a challenging topic.
Pixi is a modern package manager built on the Conda ecosystem. It integrates very well with all existing packages on conda-forge. Pixi makes package management reproducible, fast and painless – so that scientists can go back to coding instead of dealing with “dependency hell”. Pixi improves the mix Conda and PyPI package management by integrating with uv by astral.sh and streamlines automation with a cross-platform task runner. These features combined with a powerful lockfile make creating reproducible projects trivial.
This talk is for people who are interested in new, fast ways to set up their software (dev) environments on different systems – think your coworker's computer, CI, containers, and more.
