@delrod – That is on our list for this year. We are looking to add our own payment integration with Stripe & Paypal offering basic subscription management.
At this time though it does require using another plugin to facilitate the payment/membership part, our plugin can then be used to lock down your site with more precision than is typically offered.
That said our Pro offering includes ways to restrict content beyond user roles, such as if they have purchased a specific product or have an active subscription with popular WooCommerce & Easy Digital Downloads integrations.
This means you can skip a “membership” plugin to manage adding roles and changing levels etc, and simply sell subscriptions. Our plugin doesn’t have to rely on roles and can work on any conditional user data.
Hope that helps.
