Countly

Countly is an open-source, self-hosted web app and server that provides a comprehensive platform for web and product analytics. It allows organizations to track user behavior across mobile, web, and desktop applications while maintaining full ownership of their data. The software is deployed as a server application, typically on Linux environments such as Ubuntu or CentOS, and is also available via Docker for streamlined containerized deployment.

The platform focuses on data privacy and compliance, offering a way to avoid vendor lock-in by hosting the infrastructure on-premises or in a private cloud. It serves as a central hub for collecting session and event data, monitoring application performance, and managing customer engagement through various integrated tools. This makes it suitable for organizations that cannot use third-party SaaS tools due to strict security requirements or regulatory constraints.

Key features

• Collection and reporting of sessions, views, and events
• Crash and error reporting for iOS, Android, React Native, Flutter, NodeJS, Unity, Java, and Javascript
• Interactive push notifications for iOS and Android
• Remote configuration to adjust app logic and appearance without updates
• Customizable dashboards and built-in reports
• Compliance Hub for managing consent and data subject requests
• Email reports and alerts with webhooks for external data transfer
• Data Manager for planning events and segmentations

Countly is built using NodeJS and MongoDB. It employs a modular plugin-based architecture, which allows developers to extend existing features or add entirely new capabilities to the system. The software provides both read and write APIs, enabling data to be sent from any source into the backend and allowing the dashboard to be customized or integrated with other tools. It is specifically designed for teams that require strict adherence to data privacy standards such as GDPR, HIPAA, and COPPA, ensuring that sensitive user information remains within the organization's own controlled environment.

The software is a flexible analytics suite for organizations that prioritize data sovereignty and infrastructure control over traditional SaaS-based solutions.
