diskreap

Reclaim disk space from build artifacts and dependency caches — across every language, in one scan. node_modules, .venv, target, .next, __pycache__, .gradle, dist/build, and more — diskreap finds them all, shows you what's eating your disk, and deletes only what a single command can rebuild. Zero dependencies, pure standard library.

# Run without installing:
pipx run diskreap                 # scan the current directory

# Or install it:
pip install diskreap
diskreap clean ~/code             # reclaim (asks first)

Why

Every project you've ever touched left a node_modules or a target/ behind. Across a ~/code folder with dozens of repos, that's easily tens of gigabytes of stuff you never think about — until the disk fills up.

The existing tools each cover one corner: npkill is node_modules-only, kondo needs a Rust toolchain. diskreap is one zero-dependency command that reaches every ecosystem at once and refuses to touch anything that isn't safely regenerable. (A byte-for-byte twin also ships on npm as diskreap for npx users.)

What it reclaims

Safety by design: generic names like target, dist, build, vendor are only ever matched when a sibling project file proves their origin — a bare build/ folder of your own files is never touched. Symlinks are never followed, and clean always asks before deleting (unless you pass --yes).

Usage

diskreap [path]                 # scan (default: current dir)
diskreap scan ~/code            # explicit scan
diskreap clean ~/code           # delete (confirms first)

Scan

diskreap scan ~/code

Filters

diskreap scan ~/code --min 100MB        # ignore the small fry
diskreap scan ~/code --older 30d        # only stuff untouched for a month
diskreap scan ~/code --only node_modules,target
diskreap scan ~/code --json             # machine-readable

Clean

diskreap clean ~/code --dry-run         # preview exactly what would go
diskreap clean ~/code --older 60d       # reap only long-idle projects
diskreap clean ~/code --yes             # no prompt (scripts / CI)

clean accepts the same --min / --older / --only filters as scan.
