The Open Social Layer

Your data, your server

Store posts, likes, and follows on a Personal Data Server you control. Move freely between hosts without losing anything.

Algorithms you can inspect

Browse the open feed marketplace or write your own ranking logic in a few hundred lines.

Identity that follows you

Your handle works across every app on the network. No walled gardens, no migration headaches.

Made to be extended

Open lexicons and a public API let teams ship new social experiences in weeks, not quarters.
