The UI is super intuitive, it's easy to install & use for small teams or individuals as well! It integrates with GitHub so I could easily make my own contributions using Git commands if required (which was not an issue).
Would love more options like "rebase" which would be easier than having two repos at once when working in multiple branches simultaneously - but that might just me being picky :) Also don't bother installing this software yourself unless you're willing go through manual setup every time there are release upgrades from PyUp itself! Have been very happy overall since we started integrating Pipenv into our development workflow back then also had other benefits too ;).
