See what's filling your computer, and clear it safely.
JClean finds the storage you didn't know you were using: developer caches, old build folders, app leftovers, old installers and logs. It explains each one in plain language and lets you decide what goes.
How it works
- 01
Scan
A quick scan checks the places storage hides, in seconds. A full scan maps your whole home folder.
- 02
Review
Everything is grouped by how safe it is to clean, with what it is and what happens if it goes.
- 03
Clean
Safe, unused items are ticked for you. Nothing is removed until you confirm, and every clean is logged.
What it finds
Everything JClean looks for-
Developer caches
npm, Yarn, pnpm, pip, Gradle, Maven, Cargo, Go, NuGet, Homebrew, Docker build cache and unused images, and more.
-
Old build folders
node_modules, target, .next, .venv and friends, in projects you haven't touched in months.
-
IDEs, SDKs and simulators
Xcode build data and simulators, Visual Studio's installer cache, and old versions of JetBrains IDEs and Android Studio.
-
System leftovers
Windows Update downloads and old Windows versions, APT and DNF package caches, system logs, old Snap versions and Time Machine snapshots.
-
App and browser caches
Leftovers from apps, Chrome, Safari, Firefox, Slack, Discord and others. Never your history or passwords.
-
Forgotten files
Old installers in Downloads, large files you haven't opened in months, iPhone backups, and the Trash or Recycle Bin.
Safe by default
JClean is built around one rule: never remove something you'd miss. Anything that isn't clearly regenerable needs your review, and every item is checked again right before it's cleaned.
How JClean decides what's safe- Never reads file contents, only names, sizes and dates.
- Never touches Documents, Desktop, Photos, your keys or your Git repositories.
- Skips anything that changed since the scan, and anything an open app is using.
- No account, no tracking, nothing sent anywhere.
Open source, and free for good
JClean is MIT licensed. Read every line that decides what's safe to delete, suggest a new location to clean, or build it yourself.
