Is there any CMS for selling subscriptions?

Question

CMS

Comrades, respected.
Tell me a free CMS for selling subscriptions (licenses), preferably with ready-made payment gateways of the main Russian payment systems.
The task is to sell subscriptions (licenses) for access to a specific program. The program makes a request to the server and checks the status of the license and how long it has been paid for.
Thank you.
