Hyperspace
↗
Hyperspace is a macOS utility that reclaims disk space by deduplicating identical files using clone operations, keeping all files intact while sharing storage at the filesystem level.
For engineers working on macOS systems with large duplicate file accumulations, build artifacts, backups, media libraries, this provides a non-destructive deduplication path that preserves file paths and metadata. The active development cycle suggests the tool is maturing past early reliability concerns, particularly around abort handling and clone consolidation edge cases.

Hyperspace uses filesystem clone operations to deduplicate identical files without removing any of them, meaning all original paths remain valid while sharing underlying storage.
Recent releases focused heavily on reliability improvements for abort handling, clone consolidation of three or more identical file families, and verification of resource fork storage sharing after reclamation.
The tool includes Shortcuts support and scan source validation, indicating it is intended for automated or scripted workflows alongside manual use.
