ntopng vs OpenReplay: at a glance
What is ntopng?
ntopng grew from traffic monitor into asset inventory and vulnerability scanner — one major at a time
ntopng ships roughly one stable major a year. The 6.x line added vulnerability scanning and CVE support, then an Asset Inventory and Digital Twin with an assets dashboard, then autonomous-system dashboards with native ClickHouse Cloud SSL and a direct flow dump mode for real-time export. The last published release was 6.6 in November 2025, so this feed is currently quiet.
What is OpenReplay?
OpenReplay's analytics layer is mid-overhaul—breakdowns, user journeys, and clickmaps shipping in rapid patch cycles.
OpenReplay is shipping its analytics overhaul through a continuous delivery pipeline, pushing UI fixes for user-journey visualization, breakdown tables, and clickmap rendering in rapid succession. The September 2026 entries are patch-level fixes to features that landed recently, indicating a product in active post-launch stabilization rather than initial development.

ntopng grew from traffic monitor into asset inventory and vulnerability scanner — one major at a time
◆ Current state
ntopng ships roughly one stable major a year. The 6.x line added vulnerability scanning and CVE support, then an Asset Inventory and Digital Twin with an assets dashboard, then autonomous-system dashboards with native ClickHouse Cloud SSL and a direct flow dump mode for real-time export. The last published release was 6.6 in November 2025, so this feed is currently quiet.
◆ Where it's heading
Each major has annexed an adjacent category rather than deepening flow analysis: security posture in 6.0, asset management in 6.4, and infrastructure-scale visibility in 6.6. Underneath, ClickHouse has steadily replaced the older storage paths, moving from an option in 5.2 to the assumed backend with a real-time export mode. The result is a product competing well outside its original network-monitoring lane.
◆ Prediction
With the last release nine months old, the next major is overdue; based on the pattern it would extend the asset and security surfaces rather than the flow engine.
OpenReplay
5.0ANALYTICS
OpenReplay's analytics layer is mid-overhaul—breakdowns, user journeys, and clickmaps shipping in rapid patch cycles.
◆ Current state
OpenReplay is shipping its analytics overhaul through a continuous delivery pipeline, pushing UI fixes for user-journey visualization, breakdown tables, and clickmap rendering in rapid succession. The September 2026 entries are patch-level fixes to features that landed recently, indicating a product in active post-launch stabilization rather than initial development.
◆ Where it's heading
OpenReplay is expanding beyond its session replay origins into analytics: journey analytics, event-property breakdowns, and clickmaps are all receiving active development. The html-root-swap handler addresses a real edge case for SPA deployments, ensuring replay accuracy for a broader class of modern web applications. The pattern is a product widening its surface area while maintaining high release velocity.
◆ Prediction
The analytics features currently being patched (breakdowns, user journeys) will stabilize into a named release (v1.28 or v1.29) within the next two weeks, at which point product marketing and documentation typically follow.
