Open Web Analytics (OWA) is open source web analytics software created by Peter Adams. OWA is written in PHP and uses a MySQL database, which makes it compatible for running with an AMP solution stack on various web servers. OWA is comparable to Google Analytics, though OWA is server software anyone can install and run on their own host, while Google Analytics is a software service offered by Google. OWA supports tracking with WordPress and MediaWiki, two popular web site frameworks.
