Does StackAI have any big advantages over Flowise?

Hey.

I am slightly overwhelmed by all the options when it comes to LLM applications.

Does stackAI have any advantages over the free open-source langchain UI “Flowise” ?

And can someone maybe list the different usecases for all the major/relevant applications of these sorts? (Flowise, Botpress, StackAI, VoiceFlow *insert any other relevant thing of this nature.

And perhaps general tips.

Thanks in advance.
