IBM MQ

RabbitMQ is an open-source messaging and streaming broker for communication between distributed applications and microservices. It supports open protocols including AMQP 1.0 and MQTT 5.0, with client libraries for multiple programming languages. Applications can publish messages to queues or streams, route and filter them to consumers, acknowledge delivery, replicate messages across clusters, and connect deployments using shovels or federation. Common uses include decoupling services, remote procedure calls, event streaming, and IoT messaging; in the cited video, it transports events between booking services. The software is available under the Mozilla Public License 2.0, and Broadcom offers a commercial Tanzu RabbitMQ edition with enterprise support.

The system is intended for self-hosted payment platforms, SaaS payment middle offices, and merchant payment systems, and provides Java, Python, and PHP integration resources. Its backend uses Spring Boot and Spring Security, with an Ant Design Vue frontend and configurable RocketMQ, ActiveMQ, or RabbitMQ messaging.

Mu is a self-hosted personal-agent platform that provides one home for agents, tools, services, and collected data. Its server can be accessed through a web app, email, MCP, HTTP, and a command-line interface, and supports bringing your own model. Mu exposes services for mail, chat, news, video, markets, search, files, calendars, and small web applications. These services are available through APIs, the CLI, the web, or as MCP tools. Data collected by the services is archived locally so it can be searched across sources. Users can define agents by name, prompt, and permitted tools, then chat with them through the web, mail, or XMPP. The platform also provides a unified inbox for email and chat threads, including access through IMAP.

WhatsApp is a cross-platform messaging and voice/video calling application owned by Meta Platforms.
