For linux we have bubblewrap, firejail, apparmor and selinux (popular ones, there are far more). But it is often complicated and annoying to set up. Normally one would expect sw developers would write security rules for their apps but it is difficult due to amount of different sandboxing tools and various distro-specific configuration changes.
It would be nice to have it sorted out somehow. Actually Snap is an interesting example of something done in that regard.
