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!)

The goal of this project is to simplify the installation process of Mastodon to give everyone the ability to host their own fully functional (micro) instance of Mastodon without requiring any prior knowledge of the technology behind it. This all-in-one snap package also includes a database and support for ACME to automatically obtain SSL certificates for HTTPS.

Installation

sudo snap install mastodon-server

sudo mastodon-server.setup
sudo mastodon-server.get-certificate

mastodon-server.tootctl accounts create administrator --email admin@example.com --role Owner --confirmed

See the README on GitHub for more information.

Themes

Coming from Twitter/X and wanting a familiar look? Then the included Mastodon Bird UI and Tangerine UI themes might be for you. You can change the theme in Preferences/Appearance.

If you have a severe visual impairment, an accessible version of the Bird UI theme is included by default. This theme is indicated by the phrase High contrast++, which contains two plus signs and is translated into your selected language. In addition, this theme is marked with the ♿ emoji representing a person in a wheelchair as the International Symbol of Access.

This is a community developed snap and is not officially supported or released by Mastodon gGmbH.
