BuddyBoss

BuddyBoss is a WordPress plugin that brings together community features, course management, and subscription memberships in one package. It includes white-label mobile apps for iOS and Android, so your members can access your content and connect with each other from their phones without seeing your platform's branding.

It's best for organizations already invested in WordPress who want to avoid migrating their site to a separate platform. The combination of forums, activity streams, member profiles, and course content makes it work well for training programs and professional communities that need both education and social interaction.
