Introduction to publishing Asset Store packages

The Asset Store supports packages in the asset package (.unitypackage) format, and in the Unity Package Manager (UPM) format. The UPM package publishing workflow is currently a beta workflow for approved developers who want to publish free packages.

Both package types have their advantages, as follows:

• Asset packages: Best for one-off imports or sharing assets without setting up a package registry and requires fast one-off iterations. It is suited for content assets such as 3D models, UI elements that end players interact with. For more information about publishing asset packages, refer to Publish an asset package on the Asset Store.
• Unity Package Manager (UPM) packages (Currently in beta testing): Can be versioned, and excluded from source control. Use UPM when you need version control, dependency management, or plan to maintain the package across multiple projects. For more information about publishing UPM packages, refer to Publish a UPM package on the Asset Store (Beta).

Both workflows require you to create an Asset Store publisher profile before you can publish your package to the Asset Store.
