Do web applications count? Most systems can view websites somehow :)
No, because that uses a web-browser, and the computer doesn't directly execute that, it's executed by the browser.
Sorry, but nice try :)
I think that counts somehow if you prerequisite a graphical interface like a desktop environment which brings a webbrowser.
Otherwise I think he's searching for something which is compiled directly to code that machines can read like, c, c++, Delphi or Fortran :)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
