Countly

Countly is an open source product analytics and customer engagement platform founded in 2013 and headquartered in London. The company was built on the conviction that businesses should be able to understand their users without compromising privacy or surrendering data to third-party vendors. From its earliest community edition release, Countly has focused on giving organizations full ownership of their analytics data through self-hosting options and privacy-by-design architecture.

The platform provides comprehensive product analytics across mobile, web, and desktop applications, including user segmentation, funnel analysis, retention tracking, crash analytics, push notifications, and A/B testing capabilities. Countly features a modular plugin-based architecture that allows teams to enable only the features they need, customizable dashboards for visualizing data, and flexible read/write APIs for integrating with any data source. The self-hosting option gives organizations complete control over their analytics infrastructure, while the managed cloud offering provides a hands-off alternative.

Countly holds ISO 27001 certification and includes built-in GDPR compliance tools such as consent collection management and data subject request handling. As a UK-based company operating under strong data protection regulations, Countly positions itself as the privacy-first alternative to US analytics platforms like Mixpanel, Amplitude, and Google Analytics, ensuring that user data stays under the organization's control rather than being processed by advertising-driven tech companies.
