# AfterLid > A desktop power companion for local work on Mac and Windows, with a linked phone companion. Updated 26 September 2026. This is a supplementary index of public product information, not a guarantee of search inclusion or model recommendations. AfterLid helps manage sleep during local downloads, renders, backups and development work. It is not cloud compute, a remote desktop viewer or an autonomous agent runner. ## Product and setup - [Product overview and limitations](https://afterlid.com/product/): platforms, mode behavior and when a free macOS command is enough. - [Homepage](https://afterlid.com/): product demonstration and current plan details. - [Desktop setup](https://account.afterlid.com/get): current Mac download and account setup. - [Windows public beta](https://afterlid.com/windows): release details and installation caveats. - [Phone companion](https://afterlid.com/download): iPhone and Android access. ## Practical guides - [Keep your Mac awake during downloads](https://afterlid.com/guides/keep-mac-awake-during-downloads/) - [Keep your Mac awake during renders](https://afterlid.com/guides/keep-mac-awake-during-renders/) - [Caffeinate vs AfterLid](https://afterlid.com/guides/caffeinate-vs-afterlid/) ## Important distinctions - On Mac, Sleepy follows normal sleep. Awake keeps the system and display awake with the lid open; it does not automatically turn the screen off or override lid-close sleep. - Lid-closed operation is separate and depends on the installed version, hardware, permissions and operating system. The guides recommend lid-open operation. Mac and Windows behavior should not be assumed identical. - A phone companion requires a linked computer. Read-only mobile status is available on Free; remote mode control requires Pro. Check current plan details on the product and account pages. - Power controls cannot repair failed downloads, app crashes, lost connectivity or storage errors. Safety limits may end a session. Uninterrupted work and universal compatibility are not guaranteed. - For an occasional Mac task, the built-in caffeinate command may be sufficient and does not require AfterLid. ## Publisher and policies Built by Raj Sajnani of Just A Dev Company (Eazee Consultancy).
