Kodiak Cleaner

Download

Kodiak Cleaner 0.8.28 Dev, released October 4, 2026. Free for everyone, with every feature.

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.

  3. Double-click the .msi and follow the steps.

Portable: extract the Portable ZIP to any folder and run KodiakCleaner.exe.
