Thanks for the feedback. Happy to discuss how we can resolve the AGPL limitation for your work.
There are a few Ruby gem for PredictionIO, contributed by developers as well as supported by PredictionIO team, that you can choose from. We hope that the UI can assist developers manage the data engineering flow easily.
