What do you mean by is there HTML source? All pages on the internet have HTML source! If you just want to view the HTML source code, open your browser's console (Ctrl+Shift+i in Chrome).

If, however, you are referring to the source editor, which displays the wikitext source code (a simplified version of HTML and some other stuff), you can do that on any page, including user pages, via the source tab in the classic editor.
