Mastodon is a federated microblogging engine. An alternative implementation of the GNU Social project. Based on ActivityStreams, Webfinger, PubsubHubbub and Salmon.

The core ideals of this project are:

  • Independence of legacy Twitter APIs - we don't want to be compatible with Twitter clients, we want our own clients
  • In that vein, a strong and clean REST API and OAuth2
  • Minimalism. Just because you can do almost anything with ActivityStreams doesn't mean you should. Limit the set of possible functions to what makes sense in a microblogging engine. This will make federation as well as UI design a lot easier
  • Ease of deployment. The end-goal of this project is to be distributable as a Docker image.

Current status of the project is early development. Documentation, licensing information &co will be added later


  • LOCAL_DOMAIN should be the domain/hostname of your instance. This is absolutely required as it is used for generating unique IDs for everything federation-related
  • LOCAL_HTTPS set it to true if HTTPS works on your website. This is used to generate canonical URLs, which is also important when generating and parsing federation-related IDs
  • HUB_URL should be the URL of the PubsubHubbub service that your instance is going to use. By default it is the open service of Superfeedr
