RocketMQ is a distributed messaging and streaming platform designed for building event-driven applications. It serves as middleware to decouple services using publish-subscribe and request-reply patterns, and functions as a transactional messaging system that ensures atomicity by linking message delivery to local transaction outcomes. The platform includes specialized capabilities as a Kubernetes-native message broker for container orchestration environments and an MQTT broker for ingesting event data from mobile applications and hardware terminals. The system covers high-throughput data str

Postal is an open-source email infrastructure and self-hosted delivery platform. It functions as an SMTP mail server and inbound email gateway, providing the tools necessary to send and receive email through a privately managed infrastructure. The system manages SMTP infrastructure for outgoing message delivery and provides capabilities for custom email receiving. It allows for the routing of incoming external emails to internal applications or websites for automated processing. The platform includes support for multi-tenant domain mapping, event-driven webhook notifications, and plugin-base

libzmq is a C++ based asynchronous messaging engine and networking core designed for routing non-blocking messages between distributed nodes. It functions as a distributed message queue that implements the ZMTP wire-format framing protocol to standardize how data moves across different network transport layers. The library provides a multi-transport abstraction that allows a single interface to route data across TCP, IPC, and in-process memory. It incorporates a cryptographic layer to encrypt and authenticate transmissions between nodes and employs topology-based messaging patterns, such as p

Maddy is a modular mail server that assembles a complete email system by connecting small, single-purpose modules through a declarative configuration file. Rather than a monolithic stack, it lets operators compose message processing, storage, authentication, and security enforcement from interchangeable building blocks, with each module handling a specific function like receiving SMTP connections, verifying credentials, or applying policy checks. The server distinguishes itself through its flexible authentication and security architecture. It delegates user verification to external systems in

Console ist ein webbasiertes Management-Tool zur Überwachung und Administration von Kafka-Clustern. Es bietet eine grafische Oberfläche zur Verwaltung von Topics, Consumer-Groups und Echtzeit-Datenströmen. Das Projekt umfasst dedizierte Manager für Kafka Connect und die Schema Registry, was das Deployment von Daten-Connectoren und die Governance von Datenschemata ermöglicht. Es bietet ein Cluster-Dashboard zur Verfolgung von Broker-Gesundheit, Speichernutzung und Rack-Status sowie eine Schnittstelle für rollenbasierte Zugriffskontrolle und die Prüfung von Audit-Logs. Die Plattform deckt das Durchsuchen und Filtern von Daten, die Koordination von Consumer-Groups und den Aufbau von Datenpipelines ab. Zudem unterstützt sie die Überwachung von Datentransformationsaufgaben und die Verwaltung von Nutzerberechtigungen über eine zentralisierte Policy-Engine.
