On FreeBSD, Vgmi uses capsicum(4) to limit the filesystem and to enter capability mode, it also uses cap_net(3) for networking while in capability mode.

On OpenBSD, Vgmi uses unveil(2) to limit access to the filesystem and pledge(2) to restrict the capabilities of the program.

On Linux, Vgmi uses seccomp(2) to restrict system calls and landlock(7) to restrict the filesystem.

On Illumos and Solaris, Vgmi uses privileges(7) to isolate the parser processes.

On top of sandboxing the main process, Vgmi forks itself to parse foreign data in completely isolated and sandboxed processes.

• LibreSSL - fork of OpenSSL developed by the OpenBSD project
• termbox2 - terminal rendering library

• stb-image - image loading library

Executing the build.sh script will download all dependencies and build Vgmi.
