Janitor: Build Cache Cleaner
Reclaim space from dev builds
Only for Mac
$9.99
Mac
Reclaim gigabytes from Rust, Xcode, Swift, Gradle, .NET and web build folders. Scan, pick, clean, or let Janitor sweep on a schedule.
Janitor finds the build folders that quietly fill up a developer's Mac and clears them in a click: Rust target/ folders, Xcode DerivedData, Swift .build/, Gradle and Maven output, .NET bin/ and obj/, web framework caches, Python caches, dependency folders such as node_modules, and the caches behind Homebrew, pip, npm, Go, Gradle, Maven, CocoaPods, wasm-pack and sccache.
HOW IT WORKS
• Choose the folders Janitor may look at. It only sees what you approve, and it only removes build output inside them.
• Scan to see every build folder with its size, file count and the date of its last build.
• Clean what you pick, or select everything that hasn't been touched in a while. Move to the Trash or delete right away.
• Let Janitor sweep on a schedule: every hour, day, week or month, only folders older than the age you set, with a notification when it's done.
• Keep it in the menu bar with the total reclaimable space a glance away.
SAFE BY DESIGN
Every folder is identified by the project file beside it (a Cargo.toml next to target/, a package.json next to node_modules) and checked again right before removal. Your source files are never touched; the next build recreates what Janitor removed.
BUILT WITH RUST AND WEBASSEMBLY
The scanning engine is written in Rust, compiled to WebAssembly and runs inside the app in a sandbox that can only reach the folders you granted.
No account, no tracking, nothing leaves your Mac.
