Mastodon is a free, open-source, decentralized social networking service. It empowers users to host their own server nodes (instances) or join existing ones, forming a global federated network known as the 'Fediverse'. Unlike traditional social media, Mastodon prioritizes chronological timelines, user control, privacy, and an ad-free experience. The project is spearheaded by Mastodon gGmbH, a German non-profit organization, with joinmastodon.org serving as the official gateway for users to discover the platform, find instances, and learn about its development and community.
Serves as the official legal and administrative base for Mastodon gGmbH. Key functions include coordinating core software development, managing community engagement, handling finances and fundraising, and ensuring legal compliance for the non-profit entity.
The registered address is primarily for administrative and legal purposes. As a remote-first organization, there isn't a traditional large physical headquarters with notable architectural features. The 'heart' of Mastodon lies in its distributed team and global community.
The work culture at Mastodon gGmbH is deeply rooted in open-source principles, emphasizing transparency, collaboration, and community participation. Team members, largely remote, are passionate about building an ethical, user-centric alternative to commercial social media.
The Jena headquarters provides the necessary legal framework for Mastodon gGmbH to operate as a non-profit, employ developers, accept donations, and steward the Mastodon open-source project, which powers a significant part of the decentralized social web.
Mastodon gGmbH's global impact is achieved through the worldwide adoption of its open-source software, which powers thousands of interconnected Mastodon instances across diverse regions and languages. The non-profit supports this global ecosystem by developing and maintaining the core Mastodon software, fostering an international community of users, developers, and instance administrators, and promoting open standards for a decentralized web. The team itself is internationally distributed, collaborating remotely.
