Deletes only what your toolchain can rebuild.

Wipzy is a Mac disk cleaner for developers. It finds node_modules, target, DerivedData and simulators, tells you how each comes back, and moves them to an undoable quarantine.

Review plan opens the list, Move 81.2 GB to quarantine runs it, and the result reads: 67 items, 81.2 GB held in quarantine, nothing was deleted.

It reads your project before it touches it.

composer.json, package.json, Cargo.toml and 300 more markers tell Wipzy what a folder is. You see the stack with versions, the evidence, and every folder it will never touch.

What Wipzy sees in a Laravel project: Laravel 11.31, Vue 3, PHP 8.3, the evidence for each, and what can go with the command that brings it back

Four levels. Only one is ticked for you.

  1. Safe

    Comes back by itself or with one command. Pre-selected.

  2. Your call

    Comes back, but costs time: a simulator, a project you touched last week.

  3. Careful

    Might hold your work. You type clean to include it.

  4. Protected

    Source, .env, anything git tracks. Never offered.

Anything no rule recognises is Protected. Wipzy never follows a symlink.

Clean is a move, not a delete.

Everything goes to a quarantine on the same disk, checked again right before it moves. Undo puts it back, item by item. Space comes back when you press Free now, or by itself after 24 hours with Pro.

Wipzy never sends anything about your files.

No analytics and no telemetry in the app. Signed in, it asks Wipzy for your plan every 6 hours. That is the only request it makes. What an account keeps, and how to delete it

Questions

Can Wipzy delete my code?
No. Only folders a rule recognises can be offered, and source, .env files and anything git tracks are Protected. Even then, Clean moves to a quarantine you can undo.
What does it send over the network?
Nothing about your files. Signed out, nothing at all. Signed in, a plan check every 6 hours with your device token and the app version.
What if I clean something I needed?
Open History and press Undo. Items stay in the quarantine until you press Free now, or until the window you chose in Settings passes (Pro).
Why does macOS ask about Desktop, Documents and Downloads?
Wipzy scans your home folder for projects. macOS asks once per folder; say no and Wipzy skips it.
Is there a Windows version?
It's in the works, on the same Rust engine. Create an account to hear when it ships.
