CIDER is a webserver being developed by the Pappu Lab for calculating parameters relating to disordered protein sequences. Specifically, this will calculate various parameters which help translate primary sequence information into better understanding how the unstructured ensemble might behave, as well as annotating your sequence on the diagram of states (from ref [1]), which is shown below.
