Yes and it's free to do so! To create one, simply start a free 7 day trial! No payment is necessary and at the end of the trial you get to keep 4 free plugins.
If you are an existing legacy customer but you're not yet ready to move to the subscription, 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 subscription.
