Mastodon is a free, open-source social network. A decentralized alternative to commercial platforms, it avoids the risks of a single company monopolizing your communication. Pick a server that you trust — whichever you choose, you can interact with everyone else. Anyone can run their own Mastodon instance and participate in the social network seamlessly.
