Unity Licensing: What You Need to Know
When it comes to Unity licensing, there are a few key points that you need to be aware of. Unity is not an open-source software, meaning that its source code is not freely available to the public. However, there are different licensing options available for Unity.
Unity Personal License
For individuals and small businesses, Unity offers a free license called Unity Personal, which allows you to use Unity for free as long as your annual gross revenues or funds raised do not exceed $100,000.

It’s important to note that none of these licenses grant you access to the source code of Unity. The source code is not available to the public, and you cannot modify or distribute it.
So, is Unity open source? No, it is not. Unity is a commercial product with different licensing options available for users, depending on their needs and budget.

The Unity engine itself is available for free, but it does have a license that users must agree to. This license allows users to create games and applications for personal use without any cost. However, if you want to distribute your game commercially or use certain premium features, you will need to upgrade to a paid license.
While Unity is not open source, meaning the source code is not publicly available, the engine does offer a free version called Unity Personal. This version is free for personal use and provides access to all the core features of Unity.

One limitation of the free version is the revenue cap. If you earn more than $100,000 in annual gross revenue from your Unity projects, you will need to upgrade to a paid license. This helps Unity provide continued support and development for their software.
Another limitation is the lack of certain advanced features that are available only in the paid versions. For example, the Unity Personal version does not include features like real-time shadows, render-to-texture, or custom splash screens. These features can greatly enhance the visual quality and customization options of your game.
Additionally, Unity Personal does not have the same level of customer support as the paid versions. While there are forums and community support available, direct technical support from Unity is not accessible for free license holders.
It’s important to note that Unity Personal is not open source. While Unity has made the engine’s source code available to the public, it does not have an open source license. This means that developers cannot freely modify or distribute the source code of Unity itself. However, developers can still create and distribute their own games using Unity Personal.
In summary, the free version of Unity, Unity Personal, does have some limitations. It has a revenue cap, lacks advanced features, and has limited customer support. It is important to consider these limitations when choosing the right version of Unity for your game development needs.
