Reduce your memory and CPU usage by up to 60% and indirectly your battery consumption by automatically suspending the tabs you aren't using.

How many tabs do you have open that you have not used in hours or even days? That could be making your system run slower. With the Tab Suspender you can set how many minutes to wait before suspending an inactive tabs among many other options:

- Whitelist urls or domains that you do not want to suspend (You can still manually suspend them by using the menu)
- Show a screen shot of the page just before it was suspended
- Detects tabs playing audio and will not suspend them if you don't want it (experimental)
- Detects tabs that contain active forms and will not suspend them if you don't want it
- Optionally, do not suspend tabs if on battery power or no network connections
- Dark mode compatible!

- Saves scroll position so you can go back to where you were just before the page suspended

Giving 5 stars to balance out the greater than 1K tabs 2 star review

Of course if you have over 1K tabs, any thing that is trying to do anything with your tabs will mess up most personal computers. If you try doing something like this with Chrome with just 200 or so tabs on an average Mac, it'll mess up too, as you'd expect.

The developer can't put an easy disclaimer either as if you're computer is super powerful, it would be able to handle going through more tabs.

Useful app from a great dev!

I've been looking for a Safari Extention like this for a bit and this works just perfectly! Seems to save battery and CPU while browsing and having many tabs open. I had an issue with purchasing and I was able to reach out to the developer and he got it fixed for me in a very quick timeframe. Thanks for making this free with IAP for everyone to try it out.

The only working tab suspender for Safari

There are apps that allow you to save browser sessions, but there aren't any that let you suspend your tabs for later like this one.

This app has been working well and the developer is very helpful and responsive to user feedback. Would definitely recommend this quality extension.
