The work started in 2017* and a name Waltz was selected by voting at Tango Users meeting #32. Waltz is the result of joint efforts of Tango Community, HZG and IK. This paper gives an overview of Waltz as a platform for Tango web applications, the overall framework architecture and presents an end result of real-life applications**. The work shows that having Waltz platform web developer can intuitively and quickly create full web application for his/her needs. Different architectural layers provide maintainability. The platform has a number of abstractions and ready-to-use widgets that can be used by web developer to quickly produce web based solutions. Among Waltz features are user context saving, device control and monitoring, plot and drag-n-drop interface solutions. Communication with Tango happens via Tango REST API using HTTP/2.0 and Server-Sent Events. Waltz can be also treated as a system for device monitoring and control from any part of the world.
