It very much used to be, before Github delivered where SourceForge couldn't (and still doesn't). But the history is still written in project names like GForge, FusionForge; and of course the contemporary SourceHut refers to itself as a "hacker's forge".

I know whatever's written in Wikipedia doesn't necessarily have to be authoritative, but it's worth to check out https://en.wikipedia.org/wiki/Forge_(software)#History
