Pleroma

Pleroma is an open-source social networking platform that enables users to create and engage in decentralized online communities. Unlike traditional social media services owned by large corporations, Pleroma operates on a network of interconnected servers, called instances, which communicate using an open standard called ActivityPub. This setup offers users greater control over their data, privacy, and community moderation. Pleroma supports federated interactions, allowing users across different instances to follow, share, and communicate seamlessly, fostering a more distributed and user-empowered social experience.
