We also have a blog post on using indicator saturation to detect breaks discussing the Autobox comparison.

Try interactive indicator saturation using isat online – select a dataset (e.g. flow of the river Nile at Ashwan) and use indicator saturation to find sudden shifts (structural breaks) and outlying observations at a chosen level of significance:
