Technical Overview

Syrinx is a federated, peer-to-peer inspired social platform for closed communities where the server never holds your posts in plaintext. Traffic is encrypted end-to-end before leaving the sender. It relies on small independent communities connected in a mesh via federation to bypass web surveillance.

Frequently Asked Technical Questions (Syrinx)

How does Syrinx protect post privacy?

Posts are encrypted for their intended reader before leaving the author's device, ensuring the relay server never stores readable content.

What does P2P-ish mean in this context?

Because NAT makes direct peer connections difficult, a relay server forwards traffic, but that traffic remains fully encrypted between peers.

Can I self-host a Syrinx node?

Yes, it is built for small, independent servers to form closed communities interconnected in a mesh through federation.
