PackageLens – Package Import Review Tool

PackageLens is an Editor-only Unity tool that helps you inspect .unitypackage files before importing them into your project.

Importing packages can be risky when a project already contains files with the same paths, matching GUIDs, modified scripts, changed prefabs, or local edits you do not want to overwrite. Unity’s default importer is useful, but it does not always give enough context about what changed or why a file may be risky to import.

PackageLens gives you a safer review step before import. It compares the incoming package contents against your current project and clearly shows which files are new, modified, identical, binary, conflicting, or potentially moved and modified. You can review differences, inspect file status, and choose which files should be imported.

It is useful for Unity developers who frequently import asset packages, update third-party tools, test package revisions, manage local modifications, or want more confidence before bringing external files into a project.

PackageLens is not a replacement for Git, Plastic SCM, or a full source-control workflow. It is designed as a focused package import review helper that gives you more visibility before files are added or overwritten.

Because it is Editor-only and render-pipeline independent, it can be used in projects of any genre, including games, simulations, tools, prototypes, educational projects, and production workflows.
