Designed to integrate with WordPress user roles and capabilities, it can restrict access to posts, pages, categories, tags, URLs, BuddyPress and bbPress areas, downloadable files, streaming media, and selected portions of site content. Configuration uses WordPress shortcodes, with options for custom login and membership pages and registration or profile fields.

The free Framework offers content protection and PayPal Standard payment buttons for one-time or recurring payments. The paid Pro versions add one-step registration and checkout forms, unlimited membership levels, coupon and gift codes, and integrations with Stripe, PayPal Pro, Authorize.Net, and ClickBank. Pro is available under single-site and unlimited-site licenses, each with lifetime access to new versions. Files can be stored locally or integrated with Amazon services. The plugin also provides documentation, video tutorials, APIs, a knowledge base, and community forum resources to support implementation and ongoing management.
