RB WEB apps this is just console-safe apps.

As I remember in this mode are disabled methods that returns pictures via
RAM, i.e. preview methods of VREPORT classs

But save PDF or JPG or HTML into disk file will work

Yes, there is no special limits from our side

Valentina Reports exists in two modes:
    a) as Valentina Reports ADK  -- single user mode
    b) part of Valentina Server -- then multi-user mode
    
So you need 

1) V4RB ADK -- and use here InitReports, then Vproject + Vreports classes

2) and Valentina Server (you can start with free version of VServer)
    
3) Valentina Studio Pro  to design your reports in GUI

I do not think so :)

They are developed in C++, and are as effective as possible.

Yet couple years ago, our developer did profiling and benches vs other
report engines. Valentina Reports was super fast.
