ClearDisk

Your Mac is hiding 50–500 GB of developer caches. ClearDisk finds them in seconds.

A free, open-source macOS menu bar app that monitors and cleans developer caches, Xcode, npm, Homebrew, Docker, pip, Cargo, Go, Gradle, and more. No data collection. No analytics. Network access is limited to signed update checks.

Why ClearDisk?

Your Mac's SSD is full of developer caches you forgot about. Xcode DerivedData alone can eat 200 GB. Add npm, Homebrew, Docker, pip, and Cargo — and you're losing hundreds of gigabytes to files that can be safely rebuilt.

Existing tools don't solve this:

• DaisyDisk ($10) — shows what's big, but doesn't know what's safe to delete
• DevCleaner for Xcode (1,500 ⭐) — only cleans Xcode. Ignores npm, pip, brew, Docker, Go, Cargo, Gradle
• CleanMyMac ($40/yr) — bloated, expensive, trust issues
• SquirrelDisk — dead (3 years, no updates)

ClearDisk scans 79 developer cache paths in one tool. Lives in your menu bar. Alerts you when disk gets full.

Features

• 79 Developer Caches — Xcode (DerivedData, Archives, Simulators, Caches, Device Support, Logs, Previews), Swift PM, CocoaPods, Carthage, Homebrew, npm, Yarn, pnpm (store and cache), Bun, Deno, node-gyp, TypeScript, pip, UV, Conda, Poetry, pipenv, Gradle, Maven, SBT/Ivy, Gradle Wrapper, Docker, Terraform, Composer, .NET NuGet, Go (modules and build cache), Rust Cargo, Bazel, Flutter/Pub, JetBrains, Ruby (Gems, rbenv, mise, RVM, Bundler), Android (Emulators, System Images, NDK), Testing (Playwright, Puppeteer, Prisma), AI Tools (Claude Desktop, Claude Code, Ollama, HuggingFace, ChatGPT, Cursor, Windsurf), VS Code (Cache, CachedData, Extensions, Chromium Cache, Logs, Updater), Game Engines (Unity, Unity Hub, Godot), Version Managers (nvm, pyenv, mise, rustup), Cloud (AWS CLI)
• Project Artifact Scanner — Finds stale per-project caches in your project folders, including repositories kept directly in your home directory. Detects 23 project types: Node.js / JS (incl. .next, .nuxt, .svelte-kit, .angular, .turbo, .vite, .parcel-cache, .yarn/cache, dist, build), *Python (`.venv`, `venv`, `__pycache__`, `.pytest_cache`, `.mypy_cache`, `.ruff_cache`, `.tox`, `.egg-info)**, Rust, Swift PM, **CocoaPods (Pods/)**, **Carthage**, **Xcode (in-project build/, DerivedData/)**, Go, Gradle (Java + Kotlin), Maven, PHP/Composer, Ruby, Flutter/Dart, CMake, Terraform, **.NET / C# (bin/, obj/)**, **Godot (.godot/, .import/)**, **Unity (Library/, Temp/, Logs/)**, **Unreal (Binaries/, Intermediate/, DerivedDataCache/)**, Haskell, Elixir, Zig, Crystal. Each project can expose multiple artifacts (e.g. a Next.js project shows node_modules *and* .next *and* dist` separately).
