Mastodon, the decentralized social network increasingly positioned as an alternative to Twitter, has eclipsed 1 million active monthly users. That’s according to CEO and lead developer Eugen Rochko, who revealed the milestone in a post on Monday morning.

Germany-based Mastodon has experienced rapid growth since Elon Musk’s takeover of Twitter, with nearly half a million users joining the network since October 27. While a fraction of the size of Twitter’s 238 million daily active users, Mastodon’s user base remains on a steep upward trajectory, growing from 60-80 new user registrations per hour prior to October 27 to thousands of registrations per hour today.
