AppImageHub is described as 'AppImage applications for Linux without installation'. There are three alternatives to AppImageHub for Linux and Mac. The best alternative is FLATHUB, which is free. Other great apps like AppImageHub are Mac App Store (Free) and AppImageLauncher (Free, Open Source).
The Mac App Store is the best place to find apps for Mac. No more boxes, no more disks, no more time-consuming installation. Just like the App Store for iPhone and iPad, click once to download and install any app on your Mac.
Makes your Linux desktop AppImage ready. Integrate AppImages to your application launcher with one click, and manage, update and remove them from there. Double-click AppImages to open them, without having to make them executable first.
