About Eurosky
The social internet, rebuilt in Europe, under European law
Eurosky runs the accounts, relays and identity services that open social apps depend on, as a non-profit and in the public interest. Anyone can build on them. We build on them too: apps for people, tools for publishers, and a way for organizations to launch social apps of their own.
