A free, open-source social network server based on ActivityPub for self-hosted, federated microblogging communities.
What is mastodon?
Mastodon is a free, open-source social network server that enables users to create and join self-hosted, federated communities for microblogging. It is based on the ActivityPub standard, allowing interoperability across different servers and software, forming a decentralized social network known as the Fediverse. Users can publish text, links, images, and videos while following others across the network.
Communities, organizations, and individuals seeking to host their own social networks or participate in a decentralized, open alternative to centralized social media platforms.
Developers choose Mastodon for its open-source nature, adherence to open standards like ActivityPub, and ability to self-host without vendor lock-in, fostering user control, privacy, and a federated ecosystem.
