Which UML editor to choose?

Question

UML

I'm using StarUML, I ran into the problem of too many classes and the need to allocate modules.
Recommend an editor in which you can develop modules and links between them in the form of a black box, followed by detailing each module (well, or something like that, if possible opensource, preferably for Linux). Are there any such editors?

Answer 1

you want opensource whenever possible and preferably for Linux.
As far as I know there is Umbrello.

and of course Visual Paradigm is the best and most convenient, after it you no longer want to use other tools.

Answer 2

Visual Paradigm, but it is paid (although there used to be a trial that was easily reset, now I don’t know how it is).
You can use a more universal one - draw.io, but there are no checks on the connection, there are all simple graphic components (but there is more freedom). As for the details of the modules, you can add a link to the page to the block
