Kylie Jenner -- Destroying Kim, Kendall and Khloe Online

The people have spoken ... and Kylie Jenner is the undisputed Queen of the Kardashian/Jenner clan.

Kylie, Kim, Kendall and Khloe all launched their new pay websites this week ... allowing users access to their world for the low price of $2.99/month.

We found out Alaxic Smith -- CEO of communly.com -- poked around all 4 sites and unearthed subscriber numbers.

The numbers are staggering ... 891,340 people signed up for the four sites within 24-hours and here's the breakdown:

74% KYLIE

11% KHLOE

9% KIM

6% KENDALL

Smith says the loophole that allowed him access to all the subscriber info has now been closed ... not that it matters, because Kylie's already popping off on IG about her #1 status.
