# An alternative to Onyx focused on storage

Onyx is a general maintenance utility with many system tasks. MacZentra is narrower: it shows where your storage went and cleans caches, duplicates, developer junk and app leftovers, with every removal going to the macOS Trash.

## MacZentra vs. Onyx, side by side

Feature | MacZentra | Onyx |
Pricing model | Free scan, one-time purchase to clean | Free |
Focus | Storage analysis and cleanup | General system maintenance |
Disk visualization | Treemap, Sunburst and Tree View | Not included |

Deletions | Always to the macOS Trash (recoverable) | See vendor |

## Why people switch

### Built for storage

The whole app answers one question: what is using my disk, and what is safe to remove.

### Visual, not a task list

A Treemap and Sunburst show sizes, so you pick what to clean by looking.

### Safe by default

Removals go to the Trash, and scanning never changes anything.

## Frequently asked questions

Is MacZentra a good Onyx alternative?+

If your goal is freeing disk space rather than running system maintenance tasks, yes. Scanning is free in MacZentra.

Does MacZentra change system settings?+

No. Scanning is read-only, and cleaning only moves files you choose to the Trash.

Does it need an account?+

No. The licence is verified offline and doesn’t need an account.

## Scan your Mac for free

Scanning, the Treemap, Sunburst and Tree View are all free. Cleaning is a one-time $49.99 purchase. Anything you remove goes to the macOS Trash, so you can restore it.
