Mastodon
๐ฉ๐ชby Mastodon
Mastodon is a decentralized social network created in 2016 by Eugen Rochko in Jena, Germany. It operates on the ActivityPub protocol, meaning anyone can run their own server (instance) that federates with the broader network โ similar to how email works. There is no central company, no ads, and no algorithmic feed. Mastodon grew to over 10 million users after Twitter's acquisition by Elon Musk, and is governed by a German non-profit (Mastodon gGmbH).
