SpacePeek
A read-only Quick Look inspector for folders and archives.
＋ SpacePeek: Strengths

- Peeks inside folders and archives with Finder-style Quick Look
- Very cheap Pro unlock
－ SpacePeek: Weaknesses
- Read-only means no cleanup workflow at all
- No sunburst or treemap overview of a whole drive
- Niche tool, not a full disk analyzer
