I am not sure it is like sourceforge. The UI of sourceforge was always bad. Github's UI is quite solid. I actually started to hate gitlab recently because of their UI. I always feel in utter confusion when it comes to gitlab.

Same. UI "improvements" and LLM slop features instead of improving the developer experience
Compared to installing Apache, Wiki, Roundup, CVS, and Mailman on your own server, SourceForge's UI was fantastic.
