A private self-hosted Mastodon instance

For myself

Yet another private Mastodon instance.

A social platform tailored towards tech enthusiasts and multimedia content creators, however everyone is welcome!

Self-hosted Mastodon Instance for people I know.

The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!

Derzeit (noch) nur zu Test- und Entwicklungszwecken eingerichtet! (Noch) keine öffentliche Instanz!

A mostly Single-User Sharkey instance.

Mastodon.ngo gives NGOs, nonprofits, and their communities a safe, trusted home in the fediverse.
