GameCleaner scans your Steam library, flags the giant titles you abandoned, and reclaims the space in one click — your saves backed up first.
Windows 64-bit · No install · No account · Source & Linux: Python 3.10+
Drag to your library size. Most gamers haven't touched ~40% of what they've installed.
potentially reclaimable from abandoned games & caches
Each existing tool does one piece. GameCleaner does the whole job — and finds what none of them surface: the games you forgot you installed.
Sorts your library by size and flags every game untouched for months. That 120GB shooter you quit last spring? Now it's 120GB you get back. No other tool tells you when you last played.

Backs up game saves before anything is removed. Uninstall without fear.
Clear shader caches, uninstall, or move games between drives — copy, verify, then delete. Never a broken transfer.
Steam today; Epic, GOG and Xbox next. One dashboard for your whole PC — not five separate utilities.
Point it at Steam. In seconds you see every game by size and how long since you played it.
Stale 100GB titles are flagged. Pick what to clean, uninstall, or move — with a dry-run preview first.
One click. Saves backed up, space freed, library intact. Reinstall anytime from Steam.
The existing options each cover a slice. Here's the honest breakdown.

Scanning is free forever. Pay once to unlock the actions that clear space.
Before GameCleaner removes anything, your saves are backed up. Add cloud sync so a dead SSD never wipes 200 hours of progress.
One-click sync of your local game saves to encrypted cloud storage. Reinstall on any PC and pick up exactly where you left off.
Set up cloud backup →No. GameCleaner backs up local saves before any removal, and Steam Cloud saves are never touched. Uninstalling also keeps the game in your Steam library — reinstall anytime.
Yes. Shader cache is derived data the game rebuilds on next launch. You may see brief stutter the first session after, then it's gone. Nothing irreplaceable is removed.
Steam shows size per game but not how long since you played, doesn't back up saves, doesn't clean caches, and is Steam-only. GameCleaner flags stale games, estimates reclaimable space, backs up first, and (soon) covers Epic, GOG and Xbox.
Steam on Windows and Linux at launch. Epic, GOG and Xbox are on the roadmap — one dashboard for your whole PC.
Scanning and manual cleaning are free forever. A one-time $15 Pro unlocks bulk auto-clean, uninstall/move actions, save backups and multi-store support.
