Good day! Let me clarify how Spine licensing works:
Why multiple purchase buttons?
Spine offers different license tiers (Essential, Professional, and Enterprise) with different features and price points. Each button corresponds to a different license level, so you choose the one that fits your needs.
One-time payment:
For Spine Essential and Spine Professional, it's a one-time purchase - you pay once and receive all future updates for free, for life. There are no annual fees or subscriptions for these licenses.
The only exception is Spine Enterprise, which is required if your business makes $500,000 USD or more in annual revenue. Enterprise licenses are renewed annually.
No restrictions after purchase:
Once you purchase Essential or Professional, there are no time-based restrictions. You own the license permanently and get all updates at no additional cost.
Can you upgrade?
Yes! You can upgrade from Essential to Professional at any time by paying the difference in price.
You can install Spine on up to 2 computers for your own use with a single license.
