Overview
Countly is a product analytics and engagement platform covering web, mobile, and desktop, with a strong focus on data ownership and privacy. The Community Edition (server side) provides event analytics, funnels, retention, cohorts, user profiles, and crash reporting on a Node.js + MongoDB stack. A good open-source alternative to Mixpanel and Amplitude, especially for mobile apps.
Where it falls short of Mixpanel
- Many advanced features (push notifications, A/B testing, some drill plugins) are reserved for the paid Enterprise Edition.
- The Community Edition documentation and upgrade path can be rough.
- UI and query speed lag behind ClickHouse-backed competitors at large scale.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
