Open Source How I Speed Up My Asset Store Publishing Process (2026)

If you are a Unity asset developer, this is a must-read for you.

If you’ve ever published an asset to the Unity Asset Store, you probably know that the last step, packaging your work, can be surprisingly slow. For me, this step became such a bottleneck that I decided to completely rethink it. The result was a faster, automated way to create Unity packages without even opening the editor.

In this article, I explain the problem, how my workflow changed, and how Unity packages work behind the scenes.

The traditional way to create a .unitypackage is through the Unity Editor and the Asset Store Publisher tools. While this works, it comes with a lot of waiting.

Unity can take minutes just to start and prepare a project. After that, it refreshes assets, recompiles scripts, and finally lets you open the export window. Only then can you select your assets and pack them.

If you’re releasing frequent updates or maintaining multiple assets, this waiting time adds up fast. I realized I was spending more time waiting for Unity than actually improving my assets.

Instead of relying on the Unity Editor, I analyzed how Unity packages are built and how this process could be automated. Based on that, I built a tool that packages assets without launching Unity at all. It runs from the command line and can be fully automated.

Breaking the process into steps makes the difference very clear:

With Unity, even a small change can cost multiple minutes just to create a package. With the automated approach, the same task takes about 10 seconds.
