Open Web Analytics (OWA) is a comprehensive open-source web analytics framework that empowers users to track and analyze website and application usage while maintaining complete data control. Licensed under GPL v2, OWA provides an extensible platform for developers and website owners who require customizable analytics solutions without third-party data dependencies. The framework offers dual integration methods through JavaScript and PHP trackers, enabling remote logging and seamless integration with non-PHP applications. OWA supports unlimited website tracking with aggregate and individual site reporting, detailed click-stream analysis, and advanced click tracking with heat map visualization capabilities. Key features include visitor aging analysis for understanding repeat visitor patterns, referrer page analysis with anchor text and surrounding text examination, custom and canned time period reporting, and comprehensive visitor demographics including browser types, operating systems, and geographical locations. OWA also provides goal tracking, e-commerce analytics, and configurable action monitoring. The platform's architecture supports asynchronous event logging, multi-server deployment capabilities, and extensive customization through module and plugin frameworks for authentication, database access, data validation, and geo-location services. Built-in WordPress and MediaWiki integration makes OWA particularly attractive for content management system users, while its PHP SDK enables direct application integration for custom analytics implementations. OWA represents an ideal solution for organizations requiring GDPR-compliant analytics with complete data sovereignty, extensive customization capabilities, and the flexibility to integrate analytics directly into application workflows without relying on external services.
