Self hosting on desktop: how to secure self hosted apps from proprietary desktop apps? (reddthat.com)

Hello friends, I am considering self hosting on my desktop computer, which already has gentoo Linux installed. But my concern is that my regular desktop use could compromise the security of self hosted applications, which tend to handle private user data.

What can I do to secure myself against this threat?

For example, browsers on their own are a security nightmare. You are running arbitrary remote scripts, and there's no telling the extent of damage they do (most websites out there doing extensive tracking).

What can I do to secure my self hosted applications while running them on the same machine? Is there something I can do to somehow isolate browsers and other sketchy applications from the damage they could possibly do?

One option could be running your browsers and stuff with Flatpak, then you can isolate them much more easily to only have access to specific parts of the filesystem.

Otherwise you could run all the self hosted apps inside a VM, that would heavily limit what the host apps could access.
