Instead of providing a demo version of Castor CDMS, we want everyone to be able to directly experience the system and available features.

This means that you can register an account with Castor CDMS and create a test study for free - only when your study goes live, you will be invoiced for any applicable costs based upon your study design. Click on one of the buttons below to create an account on one of our servers:
