Motion with a cause
Roots descend as files are read. A moved file falls as a leaf into the Trash. A file that stays says why.
See what fills your Mac. Clear it safely.
CoreTend reads your whole Mac, shows what takes the space and gives it back in one click — to the Trash, never erased, with Undo. Free, open source, and nothing leaves your Mac.

Undoputs back what went to the Trash
Four spaces, one question each
No dashboard to decode: each space answers one question and has one main button.
HomeYour Mac in one sentence. How much space CoreTend can give back, with the one button that leads to it. Free space as macOS measures it, and what happened lately.SpaceSee what takes the space. Scan your home folder in one click: every folder becomes a block as large as what it takes. Walk in, search, sort, preview — and find exact duplicates in the same place.CleanClear it safely. Caches, logs, Xcode and simulator files, npm, pnpm, Gradle and Cargo caches, Mail attachments: read at once, grouped, each with its risk. Safe items are ticked; one review, one click, and Undo puts everything back.AppsUninstall completely. Every app with its size. Uninstall moves the app and the files it left in your Library — support files, caches, preferences, containers — to the Trash, after you see the list.
Ready in three screens
What CoreTend promises, Full Disk Access explained in one sentence (CoreTend notices when you allow it), and you start.
A greenhouse that lives
Alive, never busy
Leaves sway and pollen drifts while the window is in front — drawn by macOS itself, for almost no energy — and everything rests the moment you look away.
Calm on request
Reduce Motion, Low Power Mode or one switch in Settings: the greenhouse stands still, every piece of information still in place.
What CoreTend will never do
Erase for good
Every move goes to the macOS Trash, after your review. Undo puts it back.
Scare you
No health score, no alarm, no invented figure. Only what macOS measures, explained in plain words.
Watch you
No account, no telemetry. The only network request asks the site whether an update exists — and you can turn it off.
Give your Mac its space back.
