Chrome: allow some URLs to “never sleep” (or hibernate/discard)

Posted by jpluimers on 2021/12/29

This option in Chrome has moved around a bit, so here is how it was in Version 89.0.4389.90 (Official Build) (64-bit) when I documented it.

  1. Browse to chrome://discards/
  2. Don’t be intimidated by the many rows and columns; only the rightmost 8 (at the time of writing) are interesting:

  3. Search for the URL (in my chase , so I searched for whatsapp which you see as orange in the screenshots below) for which you want to ensure it will never sleep/hibernate (Chrome calls this “discardable”)

  4. Click Toggle under the checkmark ✔ so it changes into a cross ✘️ (so the URL will never be discarded, hence always stays awake)

Do this only for tabs that are not CPU/memory/traffic intensive

I got there via these posts:

When searching for discards, I found this post: [Wayback] How to Prevent Chrome from Reloading Tabs When You Switch to Them

Chrome has built-in memory management that causes inactive tabs to “sleep” as RAM is filled. When you click the tab again, it has to reload the page. It’s annoying.
