HierarchyCleaner

Hierarchy Cleaner is a lightweight Unity Editor tool that gives you full visibility and control over every component in a GameObject hierarchy.

• Assign a root GameObject, click Scan, and instantly see all components grouped by type - with icons and instance counts.
• Missing scripts are highlighted with a per-GameObject breakdown.
• Remove individual components, entire types at once, or strip everything in a single click.
• The tool is designed to be safe and predictable. It respects RequireComponent dependencies: if a component cannot be removed because another component depends on it, you are offered to remove both together.
• Components that Unity re-adds automatically (such as URP companion components) are detected and reported clearly.
• All removal operations support Undo (Ctrl+Z), and a multi-pass dependency resolver ensures the correct removal order even in complex chains.

Hierarchy Cleaner is ideal for:

• Cleaning up imported assets, FBX files, and downloaded prefabs before integrating them into your project
• Stripping unwanted components in bulk (e.g. removing all Colliders or all custom scripts from a hierarchy)
• Finding and removing missing scripts that cause warnings and instability
• Auditing what components exist across a complex hierarchy at a glance

The window updates automatically when the hierarchy changes, so you always see current data without needing to re-scan manually.
