The problem
Your Mac had room, and now it does not. SpaceTrace is being built to explain what filled it and what probably caused the change.

Interactive website example · Actual development UI uses sample data
Give the growing folders a name.
See measured totals for the folders you choose. Logical size, allocated space and available disk space are different measures.
Development interface · Sample data. Scroll the image on a small screen.Yesterday was smaller. Here is the difference.

SpaceTrace is read-only. It helps explain storage; you decide what to do in Finder. Measurement coverage matters.

Understanding before acting
A large item is not automatically safe to remove. The preview does not instruct you to delete system folders, application data or backups.
Release documentation
Exact scan coverage, permissions and supported macOS versions will be published with the app. The cartoon illustrates the problem, not a measured scan result.
