Pow prevails over the forces of evil. Convention defeats configuration. Don’t let tedious configuration get in the way of building great apps. With Pow, there are no preference panes to install. No Apache configuration files to update. And Pow eliminates the need to edit /etc/hosts . To get a Rack app running, just type a single command.

No maintenance required. Pow is a clean, self-contained server that runs as your user without root privileges. There are no Apache extensions to compile, no gems to install. A single command installs and upgrades Pow automatically. And your system files are left pristine and untouched.
