ActiveAnalytics

Requires custom controller patching for authentication and traffic recording, with the README admitting it 'cannot guess how you handle user authentication,' adding overhead.

Focuses on aggregate traffic insights like page views and sources, lacking advanced analytics such as real-time dashboards, user funnels, or detailed session replay.

Synchronous mode adds database write overhead per request, while async mode necessitates Redis infrastructure and manual queue flushing, increasing operational complexity.

Bot filtering requires external gems like crawler_detect, as noted in the README, meaning additional setup and dependency management for accurate data.
