Not a Crap Cleaner. A Cleaner App, Built Around What Matters.
A small, honest cleaner for Windows. Clear out junk files, fix broken registry entries, tame start-up programs and uninstall software cleanly, with no telemetry, no ads, no upsells and no background services.
Beta software: use at your own risk. Kodiak Cleaner is still in development, and more testing is needed before every feature can be confirmed to work as intended. It deletes things by design, so check what's selected before you clean and keep your own backups of anything important.
Kodiak Cleaner shows you what it found before anything is removed, so you always stay in charge.
Tick what you want to clean and click Analyze. Kodiak Cleaner measures how much each item would free. Nothing is deleted yet.
Check the results, sort by size or by when each item was last cleaned, and untick anything you'd rather keep.
Click Run Cleaner. Browsers that are open and files in use are skipped, so nothing important is pulled out from under you.
Every registry fix, startup removal and program entry change is backed up first, and most removals go to the Recycle Bin.
Analyze, review, clean. No waiting for a busy interface or hunting for buttons that moved.
Every feature is free, under the MIT License. Read the code, build it yourself, or help improve it.
Use the MSI installer, or run the portable version from any folder, even a USB drive.
Settings live in a plain KodiakCleaner.ini file next to the program. Nothing goes in AppData.
No telemetry, analytics, crash reports or upsells. It only goes online to check for updates, and only when you ask.
Three color schemes (Classic, Glacier and Honey), eight accent colors, and light or dark mode.
Cleaning, nine built-in tools, settings and safety, all in one place.
Temporary files, the Recycle Bin, thumbnail and shader caches, error reports and update leftovers, plus cache, history and cookies for eleven browsers, each shown with its own icon.
Kodiak Cleaner backs up a program's registry entries, runs its own uninstaller, waits until it has truly finished, then offers to remove the folders, shortcuts and registry keys it left behind.
Browser Extensions, Disk Analyzer, Drive Wiper, Duplicate Finder, Empty Folders, Large Files, Scheduled Tasks, System Information and System Restore. Anything removed goes to the Recycle Bin first.
See all the tools →Classic, Glacier and Honey, eight accent colors, and light or dark mode that can follow Windows.
Glacier is a thank-you for supporters. Every feature is free for everyone.

For well over two decades, I used the same cleaning app. Then came the latest upgrade.
Simple tasks got harder and familiar features moved, so Ted built his own cleaner and made it open source: a simple, private and practical tool that respects your time.
