DbVisualizer licenses are available 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 additional licensing fees.
Plus, DbVisualizer is not a subscription-based service, and your license will never expire. You’ll also receive one full year of upgrades at no additional cost.
After that, you can choose to pay a nominal fee and receive regular maintenance and upgrades, along with the capacity to install the latest DbVisualizer version(s).
Check the EULA for more details.
