Self-Hosted Social Media

Self-hosted social media refers to social networking platforms that users or organizations deploy and manage on their own servers or infrastructure, rather than relying on centralized third-party services. This approach gives users full control over data, privacy, and customization, often using open-source software like Mastodon or PeerTube. It enables decentralized, federated networks where instances can interoperate while maintaining independence.

Also known as: Self-hosted social network, Federated social media, Decentralized social media, Fediverse, Self-hosted Mastodon

Why learn Self-Hosted Social Media?

Developers should learn self-hosted social media to build privacy-focused, customizable platforms for communities, organizations, or personal use, especially in contexts where data sovereignty and control are critical, such as for non-profits, educational institutions, or activist groups. It's also valuable for contributing to the decentralized web (Fediverse) and avoiding vendor lock-in, with use cases including creating niche social networks, internal communication tools, or censorship-resistant platforms.
