As answered by people managing JavaScript Tutorial and Shake It On.
Shake It On's answer:
Shake It On's answer:
Swift, SwiftUI, and AppKit. It's a fully native macOS app, no Electron, no web views. Uses CGEvent for mouse movement, IOKit for hardware monitoring, and Sparkle for auto-updates.
Shake It On's answer:
We kept running into the same problem: Macs going to sleep during long downloads, Time Machine backups, and remote desktop sessions. Existing tools were either too simple (just an on/off switch) or no longer maintained. We wanted something that was smart enough to know when to stay awake and when to let the Mac sleep, without having to think about it.
Shake It On's answer:
Remote workers and professionals who need their Mac to stay awake during downloads, presentations, renders, builds, and remote sessions. Especially people on corporate-managed Macs where they can't change energy settings, and anyone who needs messaging apps to show them as active while they're away from the keyboard.
Shake It On's answer:
Unlike free alternatives that just block sleep at the system level, Shake It On works everywhere — including corporate MDM-managed Macs where IT has locked energy settings, remote desktop sessions, and keeps Slack and Teams showing you as active. It's a one-time $9.99 purchase with free updates forever, no subscription.
Shake It On's answer:
Shake It On uses organic, natural mouse movement instead of simply blocking sleep.
It has 12+ smart conditions that let you control exactly when it runs, It can activate only when CPU is busy, specific apps are open, you're on certain Wi-Fi networks, or external displays are connected.
It also automatically pauses when your camera is in use, a Focus mode is active, or you're on battery.
Most alternatives are simple on/off toggles. Shake It On is more like "set-it-and-forget-it" intelligent shaking.
