// 01 — usual suspects

155 GB from one real developer machine

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

The node_modules epidemic

23.94 GB of node_modules from projects you forgot you cloned

// 02 — built for your stack

Not another generic disk cleaner

DevDisk 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

Verdict before rm -rf

Each item is marked Remove, Review, or Keep so you can decide what to delete. Scan for free; unlock Trash and permanent delete with a one-time purchase.

verdict: Remove | Review | Keep

See it in action

One scan. Every dev-sized folder.

DevDisk surfaces the real offenders from an actual developer machine — Docker at 60 GB, Yarn and npm caches in the teens, orphaned app support, and the toolchain install you keep meaning to audit.

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

$ devdisk 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.
