About
Mastodon is a free, open-source, decentralized social media platform built on the ActivityPub protocol, allowing users across independently operated servers to communicate and follow one another. It offers chronological timelines, no ads or algorithms, and community-driven moderation. Users can join an existing server or self-host their own instance while remaining connected to the broader federated network.
Problem
Mainstream social media platforms control users' data, timelines, and communities through opaque algorithms, ads, and centralized corporate moderation.
For
General internet users seeking privacy-respecting, algorithm-free social media
How it works
Mastodon runs as a federated network of independently hosted servers that communicate via the ActivityPub open protocol, letting users on any server follow and interact with users on any other server.
