--- title: Distributed Flow-Based Programming via Message Queues layout: frontpage --- MsgFlo is an implementation of the [Flow-Based Programming](http://en.wikipedia.org/wiki/Flow-based_programming) using message queues as the communications layer between different processes. Currently supported message queue transports are [AMQP](http://en.wikipedia.org/wiki/Advanced_Message_Queuing_Protocol) and [MQTT](http://mqtt.org). With MsgFlo you can build robust polyglot FBP systems spanning multiple computers/devices. A node can be implemented in any language, to reuse existing code, libraries and developer know-how. In FBP each component is a black-box that processes and produces data, without knowledge about where the input data comes from, or where the output data goes. This ensures that a service is easy to change, and facilitates automated testing. MsgFlo is designed to enable partial and gradual integration into existing systems; by using standard broker/transports, not placing restrictions on message payloads, allowing to use existing queue names, and integrating non-MsgFlo nodes seamlessly.
