.appimage security

Anyone know how to contain (sandbox) .appimage files on Linux?

I have certain game launcher (I don’t wanna disclose which) that spreads through appimage. And I don’t feel comfortable game having full r/w on my /home dir.

Any advices?

P.S: what do you think about something like https://flathub.org/en/apps/it.mijorus.gearlever?

Firejail is an option.

Run firejail --appimage ./yourlauncher.AppImage and you’ve got basic containment immediately.

You can add a custom profile later to lock down specific paths like your home dir.

Also can be complimented with:

What distro are you on?

Is it worth choosing? Devs of it says it is not that safe:
