diskard

Developer-aware disk cleanup CLI. Scans your machine for reclaimable space from build caches, AI models, package managers, and IDE artifacts.

Why

Developers accumulate tens of GBs of reclaimable space — Xcode DerivedData, npm cache, Ollama models, HuggingFace cache, Docker images, Cargo target dirs, and more. diskard finds them all and lets you clean up safely.

Install

cargo install diskard

Usage

# Scan for reclaimable space
diskard scan

# Scan with JSON output
diskard scan --format json

# Scan only safe-to-delete items
diskard scan --risk safe

# Scan with minimum size filter
diskard scan --min-size 100MB

# Filter by category
diskard scan --category xcode
diskard scan --category node
diskard scan --category rust

# Sort by risk or category instead of size
diskard scan --sort risk
diskard scan --sort category

# Only show items older than 30 days
diskard scan --older-than 30d

# Combine filters
diskard scan --category xcode --risk safe --min-size 1GB

# Clean (move to Trash by default)
diskard clean --risk safe

# Clean with dry-run
diskard clean --dry-run

# Permanently delete (no Trash)
diskard clean --permanent --risk safe

# Clean a specific category
diskard clean --category node --risk safe -y

# List available recognizers
diskard list targets

# Manage config
diskard config init     # Create default config
diskard config show     # Show current config
