Aptabase is a versatile open-source analytics platform designed for mobile, desktop, and web applications. Developers can easily integrate an SDK for various supported frameworks, select specific events to monitor, and access their activity through a dynamic real-time dashboard. This dashboard features counts of events, session data, and breakdowns by app and operating system versions, as well as device types and geographical locations; in addition, users can export data in CSV format. Aptabase provides both a hosted service with options for EU or US data compliance and a self-hosted deployment alternative. With a strong emphasis on user privacy, it avoids the use of persistent identifiers, cookies, and device fingerprinting, which means it does not collect user-level metrics like monthly active users or individual retention rates. The platform supports a wide range of SDKs, catering to developers in Swift, Kotlin, Flutter, React Native, Electron, Tauri, .NET MAUI, web, React, Angular, Unity, Unreal Engine, Godot, Python, and C++. Overall, Aptabase stands out as an innovative solution for developers looking to analyze application performance while prioritizing user privacy.
