Who do these guidelines apply to?

These guidelines apply to any developer who is offering a package (tools, extension, SDK, etc) to be used in the Unity Engine. In addition, if you are an Industry or Enterprise customer, you will need a custom agreement and/or separate grant of rights to distribute your package. Please reach out to your Unity representative for more information.

Do Unity Core Standards apply to third-party AI tools and MCPs?

Are there additional standards that apply for package creators to be listed in the Unity Asset Store?

Yes. In order to list your package on the Unity Asset Store, you also need to adhere to the Asset Store Submission Guidelines. You can learn more about the Unity Asset Store publisher program here.

Do these guidelines apply to me if I distribute my package outside of the Asset Store?

Any package to be used in the Unity Engine - regardless of how it's distributed - must always be compliant with our Terms of Services and must sign packages.

Unity Core Standards

Build Better Together

Unity Core Standards (UCS) brings transparency and increased trust to the Unity ecosystem. With UCS, package providers are equipped with the knowledge and tools to showcase their offering's value, and Unity developers and advertisers can make informed decisions.

In working together with our community to advance UCS, we’re making our ecosystem stronger and Unity games faster and easier to develop, deploy, and grow.

Trust and Transparency for Unity Developers and Advertisers

Make confident, informed decisions about the tools powering your game, and better understand the quality of the inventory you are buying through upstream signals on how ads render and behave.

Guidelines and Tools for Packages

Showcase the value you bring to Unity games, meet trusted package and compatibility guidelines, and build lasting credibility with the developers and studios who rely on your tools every day.

“The gap between time spent in games and ad dollars flowing into games is not an audience problem, it's a trust and infrastructure problem. Dentsu is proud to help shape the standards that close that gap, because when gaming advertising works better, it works better for game makers, for players, and for our clients.”

Brent Koning - Dentsu
