Disclaimer: I work for Polars Inc, but my opinions are my own.
Polars itself is FOSS and will remain FOSS.
Self-hosted/on-site Polars Cloud is something we intend on developing as there is quite a bit of demand, but it is unlikely to be FOSS. It most likely will involve licensing of some sort. Ultimately we do have to make money, and we intend on doing that through Polars Cloud, self-hosted or not (as well as other ventures such as offering training, commercial support, etc).
Yep I totally get it and would probably go the same route in Polars' situation. Just sharing how some of the data teams I'm familiar with would likely be thinking about the tradeoffs.
