Kestrel
Simple, distributed message queue system (inactive)
Kestrel is a simple, distributed message queue system built originally by Twitter. Its design is relatively lightweight and is engineered for speed and simplicity. Kestrel supports queuing patterns such as enqueue, dequeue, and delayed re-enqueue (for example, when a consumer fails to process a message). It stores messages persistently on disk with a memory-backed cache, allowing recovery in case of failures. Because it is intended for relatively simple use cases, it does not provide the full feature set of some enterprise messaging systems, but is often sufficient for many asynchronous or buffered workloads. Over time, the project became inactive and is now archived. Its minimalism and ease of integration made it appealing for smaller or more controlled message-queueing needs. -

Signal Server
Server supporting the Signal Private Messenger applications on Android
Signal Server is the official backend server component that supports the Signal Private Messenger ecosystem on Android, iOS, and desktop platforms, serving as the trusted message relay, contact discovery, and push notification hub while the clients handle end-to-end encryption. Built in Java and licensed under the AGPL-3.0 license, this server software handles protocols for delivering encrypted messages, synchronizing user metadata like public keys and push tokens, and providing REST and service APIs for the client apps to interact with. Although cryptographic operations and message confidentiality are managed by the client side using the Signal Protocol, the server ensures message routing, user registration, and group updates without having access to the decrypted contents. Its codebase is public to ensure transparency and auditability for a security-focused community willing to inspect how message metadata and delivery mechanisms are implemented. -

libsignal
Home to the Signal Protocol and other cryptographic primitives
libsignal is the foundational cryptographic library that implements the Signal Protocol and other essential primitives used across the official Signal clients and servers, enabling secure end-to-end encrypted communication. Written primarily in Rust with bindings and APIs surfaced for Java, Swift, and TypeScript, this library encapsulates critical algorithms like the Double Ratchet, prekey mechanisms, secure key storage, and zero-knowledge group primitives, along with additional utilities for media handling and device key transfer. libsignal abstracts complex cryptographic constructions into reusable components that client applications can adopt to ensure forward secrecy, authentication, and integrity without re-implementing core security logic. Although its primary use is within the Signal ecosystem, its documentation and exposed interfaces allow developers to explore modern secure messaging primitives or use pieces of the protocol in experimental applications. -
