Mastodon is a free, open-source social network server based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub!)

It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! Learn more
Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!
Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos loop continuously!
Mastodon includes private posts, locked accounts, phrase filtering, muting, blocking and all sorts of other features, along with a reporting and moderation system. Learn more
Mastodon acts as an OAuth2 provider, so 3rd party apps can use the REST and Streaming APIs. This results in a rich app ecosystem with a lot of choices!
The repository includes deployment configurations for Docker and docker-compose as well as specific platforms like Heroku, Scalingo, and Nanobox. For Helm charts, reference the mastodon/chart repository. The standalone installation guide is available in the documentation.
A Vagrant configuration is included for development purposes. To use it, complete following steps:
vagrant plugin install vagrant-hostsupdater
vagrant ssh -c "cd /vagrant && foreman start"
