For software engineers & vibe coders

23.94 GB of node_modules is not a personality trait.

One scan on a real dev Mac found 23.94 GB across 124 node_modules folders — plus Docker, package-manager caches, and leftover app support. Scan for free, review every path locally, and unlock deletion with a one-time purchase.

155 GB from one real dev Mac

Actual scan results — Docker at 60 GB, Claude app support at 21 GB, Yarn and npm caches in the teens. PureMac is built around paths like these, not generic “system junk” lists.

// 02 — built for your stack

Not another generic Mac cleaner

PureMac categories map to how engineers actually fill a disk — prototypes, dependencies, toolchains, and the caches that survive every framework phase.

01

node_modules radar

Find every install tree under your home folder — including the repos you cloned once and never opened again.

find ~ -name node_modules -prune
02

Package-manager caches

npm, pnpm, yarn, pip, and Homebrew caches add up quietly. Surface them with size totals before you nuke.

~/.npm · ~/.pnpm-store · ~/Library/Caches/Homebrew
03

Build artifact graves

.next, dist, build, target, and DerivedData folders from projects at every stage of existence.

.next/cache · DerivedData · target/debug
04

Dev dashboard

Disk bar, category breakdown, and toggles for what the next scan should include — tuned for maintenance sessions.

dashboard.scan({ categories: [...] })
05

Risk before rm -rf

Each item gets a hint: usually safe cache, review first, or leave alone. Scan for free; unlock Trash and permanent delete with a one-time purchase.

See it in action

One scan. Every dev-sized folder.

PureMac surfaces the real offenders from an actual dev Mac — Docker at 60 GB, Yarn and npm caches in the teens, orphaned app support, and the Xcode install you keep meaning to audit.

  • Sortable results with size, path, and risk labels — Review First, Recommended, Safe to Remove
  • Reveal in Finder before you select anything for Trash
  • Free scanning with live progress from the Rust backend while it walks your home folder

$ puremac scan --home ~/ --categories dev,caches,large

// 03 — workflow

Fifteen minutes to free tens of gigabytes

Built for the Sunday reset before you clone another repo or spin up a new Docker stack.

  1. 1

    Check the damage

    Open the dashboard, see used vs free space, and pick categories — node_modules, dev caches, dotfiles, large files.

  2. 2

    Run a scan

    Rust backend walks your home folder with live progress. Go grab coffee; your disk won't.

  3. 3

    Audit the list

    Sort by size, filter by category, reveal in Finder. That 6 GB .next folder from March? Yeah, that's the one.

  4. 4

    Reclaim on your terms

    Unlock deletion with a one-time $9 purchase, then select what to remove and move to Trash. No silent nukes, no cloud upload of your file tree.
