Even before XProc 1.0 was finalized, EMC published the interactive XProc Designer [EMCXProcDesigner] that ran in the browser. It was built using the Google Web Toolkit [GWT]. The editor was visually appealing, but lacked an important feature: It was not possible to import other steps or step libraries. This and other features are mentioned in a feature “pipeline” but development seems to have stalled since many years.

Another recently developed visual XProc editor is GProc [GProc]. It is written in Python with a GTK+ interface, therefore it does not run in the browser. Similar to xprocedit, it is the result of a master’s thesis.
