Aptabase is an open-source product analytics platform for mobile, desktop, and web applications. Developers add an SDK for supported frameworks, choose which events to track, and view activity in a real-time dashboard. The dashboard presents event counts, sessions, app and operating-system versions, device and country breakdowns, live activity, and session timelines; data can also be exported as CSV. Aptabase offers hosted service with EU or US data residency and a self-hosted deployment. Its privacy-focused design omits persistent user identifiers, cookies, and device fingerprinting, so it does not provide user-level metrics such as monthly active users or individual retention. SDKs are available for Swift, Kotlin, Flutter, React Native, Electron, Tauri, .NET MAUI, web, React, Angular, Unity, Unreal Engine, Godot, Python, and C++.
