new here and need some help working my way around

Hello im new here, im not sure if this is the right place to ask if its not please delete it and i apologise in advance.

Im looking for a xp/leveling system for my deathrun server but i cant see any on the leaks is this because its all custom and you can not just steal one?

it is something i would even be willing to pay for but again im not sure if this is possible or not.

thanks for your time.
