While XAMPP is a full-featured local web server package and is available on the three major operating systems, there are many others available online. Most of these packages will run the required web services on the computer directly, while more advanced packages, such as Varying Vagrant Vagrants (VVV), will virtualize a Linux-based web server on your computer to create a more accurate replica of a final deployment environment optimized for WordPress. Here is a list of some of the most popular local web server packages:
