Mastodon gGmbH is a non-profit in Germany (HRB 230086 B)

If you are a business/enterprise sponsor and need invoices for tax purposes, you can sponsor Mastodon through our own portal (Gold tier and higher only)

We are working on Mastodon, a free, open-source, decentralized social network based on the open web protocol ActivityPub. The social focus of the project is creating viable alternative to commercial social media silos that returns control over global communication back to the people. The technical focus of the project is a good, friendly user interface, a clean REST API for 3rd party apps and robust anti-abuse tools.

The entire network is like an unlimited number of different Twitter websites, operated completely independently, users of which can follow each other and interact regardless of which Twitter website exactly they are on. This has obvious benefits as there is no single company that has a monopoly.

The code of the project is available on GitHub. Besides the development of Mastodon itself, we develop and maintain:

Official Mastodon app for iOS
Official Mastodon app for Android
Mastodon server mastodon.social, currently hosting over 693,000 users
Mastodon server mastodon.online, currently hosting over 93,000 users
joinmastodon.org, the homepage of the project and related APIs
docs.joinmastodon.org, the documentation for the project

By supporting this Patreon you help pay for the hosting and maintenance of the above resources, as well as the development of the project, expansion of the team and other related projects.
