What Keep Awake (Display | System) does
Keep Awake (Display | System) offers a toggle to prevent either your display alone, or your entire system, from sleeping. This gives you a choice: keep just the screen lit for something like a presentation, or keep the whole machine running for a longer background task, without changing your operating system's sleep settings manually.
Is Keep Awake (Display | System) free?
Yes, it's free to install and use from the Chrome Web Store. There's no listed paid tier; the extension is a single-purpose power-management toggle.
Is Keep Awake (Display | System) safe?
Because it overrides sleep and screen-dimming behavior, it needs system-level power permissions, which is required for both its display-only and full-system modes to work. It doesn't need access to browsing content or history to function.
