Wise Memory Optimizer
A long-running free utility. It frees memory on demand or on a schedule and is a reasonable choice if you want free and simple. It is part of a larger suite of Wise utilities, so expect cross-promotion.
Razer Cortex
A game booster: it closes background processes when a game launches and shows FPS overlays. If your goal is gaming performance, it is purpose-built. If you just want to free idle memory while keeping your apps open, it is more than you need.
MemoryCleaner
Built for one job: show which apps use memory, and release the idle pages in one click without killing anything. 2.5 MB, no ads, no telemetry, one-time $20 for up to 5 devices, 30-day trial. No account, no subscription.
When none of them is the answer
If memory is high with nothing open, the fix is not a cleaner — check Startup apps, run a malware scan, or reboot to clear a leak. A memory tool helps most when you keep many apps open and want to free idle pages without closing them.
