Development tools quietly fill your disk. Android SDKs and emulators, Gradle and Maven caches, npm and Yarn packages, IDE caches for every version you have ever run, and a dependency folder in every project you have ever built.

This shows you all of it at once: which area is the worst, which single folders are the biggest, and — for every entry — whether removing it costs you nothing, a download, or something you cannot get back.

What it does:

• An overview that answers "where did it go" at a glance
• Grouped by what you work with: IDEs and editors, Android, Java and Gradle, JavaScript and Node, Python, Rust and Go, C/C++ and build systems, containers and packaging, embedded, your own projects, logs
• Rates every entry Safe, Caution or Risky, and says why
• Finds dependency and build folders inside your own projects
• Leaves the newest SDK and toolchain versions alone
• Only lists what is really installed on this machine — nothing else clutters the window
• Counts what the filesystem counts, so the figure matches what you get back
• Refuses to touch system folders and other people's files
• Deletes only what you ticked, after a confirmation that says so
• Available in 44 languages: English, German, French, Spanish, Italian, Portuguese, Catalan, Dutch, Polish, Czech, Slovak, Slovenian, Croatian, Serbian, Bulgarian, Romanian, Hungarian, Swedish, Danish, Norwegian, Finnish, Lithuanian, Latvian, Greek, Turkish, Russian, Ukrainian, Japanese, Chinese (Simplified), Chinese (Traditional), Korean, Vietnamese, Thai, Indonesian, Malay, Tagalog, Hindi, Bengali, Nepali, Urdu, Persian, Arabic, Hebrew, Swahili (Automatic follows the system language)
• Light and dark theme

▶ ONE-TIME SETUP

sudo snap connect jsdevcleaner:system-backup

Developer caches live in hidden folders — ~/.gradle, ~/.npm, ~/.cache — and a confined app cannot even see them until you allow it. This permission is read-only: it lets the app measure those folders, and it changes nothing by itself. No reboot, just restart the app.

Anything the sandbox will not let the app delete is collected in a list of its own, and one click opens it in your file manager — which runs outside the sandbox with full access.

Supported systems:

• Ubuntu 24.04+, Fedora 40+, Arch Linux, openSUSE Tumbleweed
• Any Linux desktop with X11 or Wayland
• x86_64 (64-bit)

Also available as .deb, .rpm, Flatpak and AppImage at www.budbrain.de

▶ PLEASE NOTE

This app deletes permanently — there is no undo, and nothing is moved to the trash. Nothing is preselected: you tick every item yourself, each one is rated Safe, Caution or Risky, and a confirmation says so before anything goes. Please check your selection before you confirm, and keep a backup of anything you cannot recreate. The software is provided "as is", without warranty of any kind, and is used at your own risk.
