How these tools were selected
Selections compare documented features and the job described in this guide. We did not run a common benchmark, assign performance scores, or audit every app’s code. Official sources appear under “Sources and how we compare.” Requirements and prices can change.
NullDisk is proprietary. It is not an open-source recommendation; its free direct Mac edition is listed separately in the free-tool guide.
Common questions
Is NullDisk open source?
No. NullDisk is proprietary and is not included in this open-source shortlist. Free use is a licensing/pricing choice, not source-code availability.
Is JDiskReport open source?
Its vendor describes it as no-charge freeware. That is not an open-source license, so it is excluded here.
Does open source guarantee privacy or safety?
No. Review the implementation, dependencies, network behavior, and removal actions of the version you install. Source availability permits inspection; it does not guarantee it occurred.
