01 · The problem
Your disk is full, and nothing tells you why.
Developer Macs don’t fill up with documents. They fill up with things that can be rebuilt: .next and .turbo folders, Rust targets, iOS and Android builds, node_modules in worktrees, caches and Docker images. General cleaners either miss them or offer to delete things they can’t explain.
02 · What I built
Built for the mess developers make.
Docker
Shows images, volumes and build cache, and how much each one takes.
Ports
Lists what’s running on which port, so a stuck dev server is one click away.
Disk map
A visual map of where the space has gone, plus leftovers from apps you’ve removed.
Growth watch
Notices when a folder starts growing fast, before the disk fills.
Same engine, two ways
The SwiftUI app and the plumb command line share one engine, so scripts and the app always agree.
03 · Key decisions
Safe by design, not by luck.
Three levels of safe
Everything is sorted into Safe, Check first or Your call, with the reason in plain words. Your call items are never ticked for you and go to the Trash.
Five checks, twice
A build folder is only suggested if it hasn’t changed in two days, no dev server is running, it’s a name tools always generate, it isn’t a link and git ignores it. Every check runs again just before removal.
