DbVisualizer is licensed per USER -- not per machine. We’ve done this so that you can benefit from our product at home and in your office without paying more than a single subscription fee. 

DbVisualizer is from January 2022 made available as a subscription. With an active subscription, you have access to security and software upgrades, as well as support. If you choose to end your subscription, you can continue to perpetually use any version made available during your active subscription term. 

Check the EULA for more details.
