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 moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

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 moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.
◆ Current state
On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.
◆ Where it's heading
The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.
◆ Prediction
Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
