Yes and it's free to do so! To create one, simply start a free 14 day trial. No payment is necessary.
If you are an existing customer but you're not yet ready to move to the Annual Service Plan you can still trial the Astute Manager if you haven't already. After the trial ends however, you will need to remain with use of the Unified Installer for installation of your plugins until you are ready to move to the Annual Service Plan.
