From the very beginning, interaction with other control systems has been a key requirement for Karabo [1], particularly with DOOCS [2], which is in use for the XFEL accelerator at DESY. Hence, different interfaces were developed for bi-directional communication between Karabo and DOOCS. The most recent one offers a user-friendly generic GUI for exposing any DOOCS location to the Karabo system. Later on, we followed the same approach (i. e., a generic interface) to develop interfaces to other well-established control systems, namely Tango [3] and EPICS [4]. The purpose was to ease the integration of new hardware devices, including user-provided ones, but also to encourage the use of Karabo outside the European XFEL facility. On top of that, we developed the Karabo WebProxy, an HTTP server to expose parts of a Karabo ecosystem to any other software, and its companion Karabo-Proxy [5], an open source Python client to interact with it.
