Helper application for Linux distributions serving as a kind of "entry point" for running and integrating AppImages

This should be installed as default in all distro.
Run it with --install, put appimages in ~/Applications and it's done, you'll see all apps in your DE app men

Gearlever alternative:

I agree, this is a very handy app, and I felt very similarly when I first discovered it. That said, I've had some issues with AppImageInstaller that I haven't had with GearLever, it's nearest equivalent. That's the beauty of Linux FOSS though, so many choices

GearLever works better

Does it manage the --no-sandbox option often needed?

No appimage for gearlever???

I have never used that flag. Does that just enable full system access without the usual layer of sandbox protection?

Yes,and it's the only way to start some apps on Ubuntu

Overall there should be repo for appimages which just don't have flatpak, for some apps which can't work well in sandbox.

Does it have GUI?

It was recently tested on postmarketOS here btw

Trying AM now, looks good although I'm using it as appman in userspace and imi noticed it unpacks all appimages in the application folder, I'd prefer to have them as appimages files.
And the store misses curseforge appimage.
