DiskWise is a native SwiftUI disk cleaner for macOS: node_modules, Xcode DerivedData, Docker volumes, app caches, leftovers. It measures real on-disk usage, not apparent size, and every row says what it is and what deleting it costs. There is no delete code path: everything moves to the Trash and stays undoable until you empty it. Free, open source, no telemetry, ~8 MB, 10 languages. Ships a CLI that doubles as an MCP server, so Claude Code can clean up for you.

Hi Product Hunt — maker here.
I built DiskWise because I kept hitting the same wall: every disk cleaner tells you a folder is 28 GB and then asks you to trust it. Not one of them tells you whether that folder is a cache the app rebuilds in ten minutes, or something with no second copy.
So I started from the other end. Every location in DiskWise carries a written note — what it is, what happens if you delete it, how it comes back. That knowledge base is the actual product; the UI is a viewer for it.
The decision I'm most attached to: there is no delete code path. Not a secure-delete warning, not an rm -rf behind a checkbox — every removal is a move to the Trash, undoable until you empty it yourself. If I misjudge a folder, your recovery is Finder, not a data-recovery service.
It's free and open source, no telemetry, no account. The direct build also ships a CLI that doubles as an MCP server, so Claude Code or Cursor can work the same plan under the same guardrails.
One question for you: when a cleaner says safe to delete, what would actually make you believe it — a written explanation per item, an undo stack, or the source being open? I've bet on all three, and I'd like to know which one carries the weight.
