⚡ Don't Lock My PC¶

Keep your computer awake and unlocked while long-running AI agents do the work — then let it sleep normally when you're done.

“While AI agents are working, your system should never lock or sleep.”

Don't Lock My PC — app window

Why this exists¶

AI agents and automated workflows often run for minutes or hours. If you walk away, corporate or personal lock-and-sleep policies kick in — locking the screen, sleeping the machine, or turning off the display. That can pause the agent, drop an RDP session, or interrupt the task entirely.

Start Don't Lock My PC before a long run and it keeps everything awake until you click STOP — no registry hacks, no policy changes you can't undo.

🤖 Built for agent runs¶

Start it before a lengthy agent or automation task so the session never locks or sleeps mid-run.

🖥️ Cross-platform¶

One codebase, one identical UI on Windows and macOS, with OS-native mechanisms behind a small backend abstraction.

💤 Lid-close stay-awake¶

On Windows, optionally keep working with the laptop lid shut — your original power setting is restored on STOP.

⏻ Scheduled power action¶

Sleep, Hibernate, or Shut down after a timer — “keep my PC awake for the agent, then power it off when done.”

🫥 Zero footprint¶

An invisible F15 keypress and ±1px mouse nudges. No clicking, no typing, no interference with your work.

Optional autostart via the Windows Run key or a macOS LaunchAgent, so it's ready before your next run.

Full installation guide How it works

How it keeps you awake¶

Platform	Prevent sleep / display off	Reset lock / inactivity timer
Windows	`SetThreadExecutionState` (`ES_SYSTEM_REQUIRED` \| `ES_DISPLAY_REQUIRED`)	`SendInput` mouse ±1px + invisible F15 keypress
macOS	built-in `caffeinate -dimsu` subprocess	Quartz `CGEvent` mouse ±1px + invisible F15 keypress

Why both mechanisms?

On Windows, SetThreadExecutionState prevents sleep but does not reset the screen-lock timer — which is why the mouse + F15 nudge is also needed. On macOS, caffeinate handles sleep while the Quartz events keep the session active.
