Social Network Stack

A social network stack is a software architecture designed to support user identities, social relationships, content sharing, realtime interaction, community engagement, and personalized content delivery at scale. These architectures power social media platforms, professional networks, creator ecosystems, online communities, discussion platforms, and applications with social features.

The primary goal is to enable meaningful interaction between users while managing identity, relationships, content distribution, engagement, moderation, and realtime activity across growing communities.
