Cookie Clicker is a single-player game with no leaderboards or competition element whatsoever. The design philosophy behind the whole game is that it’s built like a regular old desktop program - you should be able to cheat, mod and abuse the game as much as you want. Of course, once you cheat in a gazillion cookies and unlock everything, you’ll have to ask yourself if you can still sleep at night, look your kids in the eye, live with yourself and kiss your mother with that mouth.
