    VirtualBox vs VMware Fusion opinions
    Almost everyone thinks VirtualBox is a great alternative to VMware Fusion.
    ByteRanger

    While VirtualBox has never failed me on a Linux host, I have never been able to get VirtualBox working reliably on MacOS. The free/opensource part of VirtualBox doesn't even hold a candle to VMware feature wise. The added extensions module that makes it more comparable to VMware is only free for personal use, and the commercial license is priced like VMware's server offerings, many times more expensive than VMware Fusion Pro.

    VirtualBox is almost always the better option compared to VMWare. Open source and free, works on Windows, Mac and Linux. Vital and important software for running virtual machines, testing other operating systems, etc.
