01 — features

Built for how developers actually work

SlimWin targets the exact caches, artifacts, and bloatware that accumulate on development machines. Not another generic disk cleaner.

developer_caches

60+ Dev Tool Caches

npm, NuGet, pip, Cargo, Maven, Gradle, Go, Composer, and dozens more. Package managers accumulate gigabytes over time.

docker_wsl

Docker & WSL

Remove unused Docker images, stopped containers, dangling volumes, and build cache. Compact WSL virtual disks.

bloatware

Bloatware Removal

Remove 30+ pre-installed Windows apps: Candy Crush, Xbox apps, Cortana, Copilot, and manufacturer junk from HP, Dell, Lenovo.

ide_editors

IDE & Editor Caches

Visual Studio, VS Code, Cursor, all JetBrains IDEs, Neovim, Vim, Zed, Helix, Sublime Text, and more.

safety_levels

4-Tier Safety System

Every item is color-coded: Safe (auto-select), Caution, Review, or Dangerous. You always know the risk before deleting.

reports

Detailed Reports

See what's using space with charts and breakdowns. Export to TXT, CSV, or JSON. Script it in CI/CD pipelines.

02 — what_it_cleans

Every corner of your dev machine

Typical developer machines recover 10-50 GB. Heavy Docker users often find 20+ GB in unused images alone.

03 — safety

You always know the risk

Every cleanup item is categorized into a safety tier. Safe items auto-select. Dangerous items are never auto-selected and require explicit confirmation.

SAFE

Auto-selected

Regenerates automatically. Zero risk. Browser caches, temp files, build caches.

CAUTION

Not auto-selected

May cause one-time slowdown as packages re-download. Package manager caches, IDE caches.

REVIEW

Manual review

May contain files you need. node_modules, Maven repo, old downloads.

DANGEROUS

Explicit confirmation

Never auto-selected. Potential data loss. Global npm packages, .NET tools, WSL distros.
