Your Mac is full of build output you forgot you made.
DevSweep finds the caches, dependency trees and build artefacts your tools quietly leave behind, works out what each pile of bytes actually is, and tells you which ones are safe to remove — with the evidence for saying so.
One-time purchase, no subscription, no account. 30-day refund, no questions asked.
What it does
Why the numbers are different
It measures what you get back
Sizes come from blocks actually allocated, not the length a file claims. Docker's disk image on the machine this was built on reports 994 GB and occupies 17 GB. A cleaner that reads the claimed size is wrong by a factor of 58.
It counts shared files once
pnpm hard-links one copy of a package into every project that uses it. Counting each link separately multiplies the total by the number of projects and promises space that does not exist.
It reads Git before it touches a project
Uncommitted changes, unpushed commits, stashes, files that are tracked rather than ignored, whether a lockfile pins what a reinstall would fetch. Age alone is not evidence that work is safe to remove.
It says what it could not see
Locations it could not read are named, not quietly dropped from the total. A smaller number presented as the truth is worse than an honest gap.
What it never touches
- Source files and Git history. Never offered, never selected, never removed. No setting changes this.
- Anything it cannot justify. Removal works from a list of permitted locations, not a list of forbidden ones. A path that is not on the list is refused, whatever asked for it.
- Credentials.
.ssh,.aws,.gnupg,.kube, keychains and.envfiles are refused wherever they appear — including inside a cache it was otherwise allowed to clear. - Docker's disk image. Space is reclaimed through Docker's own commands. Deleting that file by hand destroys every image and volume at once.
- A project that is still in use. If something wrote to it minutes ago, cleanup is blocked and the reason is shown.
Every decision is explained
Price
For comparison: the smallest storage upgrade Apple sells costs several hundred, and 2 TB of iCloud is about $11 every month, forever.
- The scanner is free forever, with or without a licence
- Unlimited cleaning
- Project intelligence and Git evidence
- Scheduled scans, menu bar and notifications
- Every toolchain module added from here on
- Works offline. No account, no subscription, no server
Your licence key arrives by email straight after payment and is shown on screen. 30 days to change your mind, no justification required.
Privacy
Scanning, hashing and cleanup all happen on your Mac. No filenames, paths or source code are ever uploaded. There is no account and no activation server: your licence is a signed file the app checks by itself, offline.
The one exception is the update check, and it is off until you turn it on. It fetches a signed list of releases and sends nothing about you or your machine. Full privacy statement.
