Does SCP SL cost money?

Could you please clarify for me if there is a cost associated with SCP SL? Are there any fees or charges that I need to be aware of before I start using this service? Is it a free platform or do I need to make a payment to access its features? It would be great if you could provide me with some insight into the financial aspect of SCP SL so that I can make an informed decision about whether or not to use it.
