Mastodon is a free, open-source social network server based on ActivityPub. Follow friends and discover new ones. Publish anything you want: links, pictures, text, video. All servers of Mastodon are interoperable as a federated network, i.e. users on one server can seamlessly communicate with users from another one. This includes non-Mastodon software that also implements ActivityPub!

No vendor lock-in: Fully interoperable with any conforming platform

It doesn’t have to be Mastodon, whatever implements ActivityPub is part of the social network! Learn more

Real-time, chronological timeline updates

See the updates of people you’re following appear in real-time in the UI via WebSockets. There’s a firehose view as well!

Media attachments like images and short videos

Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos are looped - like vines!

Safety and moderation tools

Private posts, locked accounts, phrase filtering, muting, blocking and all sorts of other features, along with a reporting and moderation system. Learn more

OAuth2 and a straightforward REST API

Mastodon acts as an OAuth2 provider so 3rd party apps can use the REST and Streaming APIs, resulting in a rich app ecosystem with a lot of choices!


Tech stack:

  • Ruby on Rails powers the REST API and other web pages
  • React.js and Redux are used for the dynamic parts of the interface
  • Node.js powers the streaming API


  • PostgreSQL 9.5+
  • Redis
  • Ruby 2.4+
  • Node.js 8+

The repository includes deployment configurations for Docker and docker-compose, but also a few specific platforms like Heroku, Scalingo, and Nanobox. The stand-alone installation guide is available in the documentation.

A Vagrant configuration is included for development purposes.
