Streamsheets enable users to build simple and complex apps and services that process, visualize, connect, and control data streams without writing a line of code. Typical Streamsheets applications include the visualization, analysis, simulation, and control of IoT devices via MQTT or REST as well as the real-time processing and analysis of data from event streaming platforms such as Apache Kafka. Streamsheets run in any cloud, on-premises as well as in hybrid infrastructures and not only fully support but also communicate between all common IoT protocols, such as OPC UA, MQTT, REST, and Kafka.
