If your .vimrc is minimal, you will have a pretty good time using systems that implement "vim like" text editing. Take Overleaf for example, no vimrc is available, but I'm quite happy with what I got, and sometimes I even forget I'm in the browser.

This has not been my experience, fwiw. Everywhere implements "most" of what I do, but I still wind up hitting something in the unimplemented portions pretty frequently.
