jsDevCleaner

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.
