Self-hosted product analytics platform for mobile, web, and desktop
Track, analyze, and act on user behavior across mobile, web, and desktop applications with full control over your analytics data flow.
Countly is a product analytics platform designed for teams who need complete control over their user behavior data. Built for mobile, web, and desktop applications, it processes billions of data points daily across 2,000+ servers worldwide, tracking 1.5B unique identities on 16,000+ applications.
The platform delivers session tracking, event collection, crash reporting, push notifications, remote configuration, and in-app ratings through a plugin-based architecture. Teams gain access to customizable dashboards, email reports, consent management via Compliance Hub, and comprehensive APIs for data integration. The server supports crash reporting across iOS, Android, React Native, Flutter, Node.js, Unity, Java, and JavaScript.
Countly offers three editions: Countly Lite (free, non-commercial, self-hosted for individuals and small teams), Countly Enterprise (self-hosted or managed with SLA and direct support), and Countly Flex (fully-managed SaaS with regional deployment). Built on MongoDB, Node.js, and Linux, installation on Ubuntu or CentOS takes a single command. Docker support is available for containerized deployments.
When teams consider Countly, these hosted platforms usually appear on the same shortlist.
