Pleroma is a lightweight, decentralized social networking platform that allows users to create and join their own social communities, known as instances. Built with a focus on performance and usability, Pleroma is designed to be flexible and easy to host, making it accessible for users who wish to maintain control over their data. It supports ActivityPub, enabling seamless interaction with other federated platforms such as Mastodon and Friendica, thus promoting an open and interconnected social experience. Pleroma's interface is customizable, and it offers various features like rich media support, user timelines, and an extensive API for developers.
As an open-source project, Pleroma encourages community contributions and offers detailed documentation for users interested in self-hosting or customizing their own instance. Its architecture is built to be efficient, allowing even modest hardware to effectively handle significant user traffic. By providing a compelling alternative to mainstream social media, Pleroma champions the principles of decentralization, user agency, and privacy in online communication.
