Kodiak Cleaner

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.

Kodiak Cleaner

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.

How It Works

Open It, Clean It, Get On With Your Day

Kodiak Cleaner shows you what it found before anything is removed, so you always stay in charge.

Analyze

Tick what you want to clean and click Analyze. Kodiak Cleaner measures how much each item would free. Nothing is deleted yet.

Review

Check the results, sort by size or by when each item was last cleaned, and untick anything you'd rather keep.

Clean

Click Run Cleaner. Browsers that are open and files in use are skipped, so nothing important is pulled out from under you.

Why People Choose It

Everything You Need, Nothing You Don't

Backups Before Changes

Every registry fix, startup removal and program entry change is backed up first, and most removals go to the Recycle Bin.

Fast and Familiar

Analyze, review, clean. No waiting for a busy interface or hunting for buttons that moved.

Free and Open Source

Every feature is free, under the MIT License. Read the code, build it yourself, or help improve it.

Installed or Portable

Use the MSI installer, or run the portable version from any folder, even a USB drive.

Local First

Settings live in a plain KodiakCleaner.ini file next to the program. Nothing goes in AppData.

No Ads, No Tracking

No telemetry, analytics, crash reports or upsells. It only goes online to check for updates, and only when you ask.

Your Look

Three color schemes (Classic, Glacier and Honey), eight accent colors, and light or dark mode.

Programs

Uninstall Cleanly, Leftovers and All

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.

  • Uninstall several programs, one at a time.
  • Repair, Rename or Delete Entry for broken listings.
  • History records every change and can restore it.

Why It Was Made

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.
