Toolchains and IDEs
The classics that quietly accumulate tens of gigabytes of build artifacts and package caches:
- Xcode, including DerivedData, archives, DeviceSupport and the Swift Package cache
- iOS simulators via the Simulator Slimmer, with a per-device and per-runtime breakdown and one-click removal of unavailable simulators
- Android Studio and the Android SDK
- JetBrains IDEs (IntelliJ, PyCharm, WebStorm and the rest)
- VS Code caches, crash reports, workspace storage and file history
- CocoaPods, Homebrew, npm / Yarn / pnpm, Python, Flutter, Rust, Go, Maven, Composer and Unity
- Custom folders you add yourself
AI coding tools
The newest disk hogs. DevCleaner separates throwaway caches from things you might want to keep:
- Claude (the desktop app and the Claude Code CLI)
- ChatGPT, Gemini CLI, Cursor, Windsurf and Antigravity
- Ollama and LM Studio
Editor and app caches are rated SAFE. Downloaded LLM model weights in Ollama and LM Studio are rated WARNING and are never pre-selected, because re-downloading them is slow. Session transcripts and workspace storage are opt-in too.
Docker and containers
DevCleaner reads sizes straight from Docker, OrbStack and Colima, and can clear:
- The build cache
- Dangling and unused images
- Stopped containers
- Unused volumes
Volumes can hold databases and other persistent data, so they are rated DANGER and never touched unless you explicitly select them.
How ratings work
Across every tool, the same three levels apply: SAFE regenerates for free, WARNING is slow to rebuild, and DANGER can break your setup. Read more in how DevCleaner keeps you safe.
