Flatline Server

Independent server implementation for the Signal protocol, enabling secure communication and data encryption at rest.

Product Information

Description
Flatline Server provides a standalone implementation of the Signal protocol's server-side components, allowing organizations and developers to deploy private, secure communication infrastructure. It enables end-to-end encrypted messaging by managing user registration, key distribution, and message routing while ensuring all stored data remains encrypted at rest. Key features include support for secure group messaging, forward secrecy through regularly rotated keys, and compatibility with existing Signal clients through standardized APIs. This server solution is particularly valuable for enterprises requiring controlled communication environments, privacy-focused applications needing custom infrastructure, or researchers studying secure protocol implementations without relying on centralized services.
