The Buckaroo lowcode UI is capable of working with Polars, but I don't currently have any commands plumbed in. I will work on that.
I'm aware of Data Wrangler and they did nice work, but it's closed source and from what I can tell non-extensible. What features do you like in Data Wrangler, what do you wish it did differently?
I need to make some updates to the polars functionality, I just completed some extensive refactorings of the Lowcode UI focussed on pandas, time to clean that up for polars too.
Also the python codegen for polars is non-idiomatic with multiple re-assignments to a dataframe, vs one big select block. I have some ideas for how to fix that, but they'll take time.
