FAQ

Good to know

Project Cleaner shows you what it found for review. It only removes files after you approve the deletion.

Can I run scans from code?

Yes, the public API lets you trigger Issues, References and Cleaner scans from your own editor tools or CI.

In their words

★★★★★

Essential in every project!

This tool is really useful and is something should have been included with unity from the get go! I use it in every project and it really helps especially when working on large projects with multiple people editing and ensuring that nothing got screwed up before a build or deployment.

Exactly what I looked for

It did clean up my project from stale assets in a few clicks and it does good job navigating references. Issues finder now runs as part of our CI/CD to validate critical issues are not getting into production. This is my go-to asset for the new projects from now on, thank you for the quality product with long lasting support.

Should be bundled with Unity

Maintainer has been crucial for keeping track of prefabs scattered about many scenes. It keeps an index of all references throughout all project scenes, which it builds and accesses super quickly. I gave some feedback on some UX issues I was having in the discord and the developer quickly fixed it and deployed it in the next update. Highly recommend this asset for virtually any project!
