OpenObserve vs ntopng: at a glance
What is OpenObserve?
OpenObserve is running a stabilization train on 0.91 while 0.92 gathers features in RC
Two branches are moving at once. The 0.91 line has taken four patch releases since the start of July, each carrying two or three fixes — memtable rotation, RBAC migration for metric stream names, PagerDuty integration bugs, an anomaly-detection threshold that no longer forces a retrain. In parallel, 0.92 is accumulating in release candidates: agent-level filters, an option to disable default index fields via ZO_FEATURE_DEFAULT_INDEX_FIELDS_ENABLED, and parallel zstd compression. The substantive 0.91.0 release itself — Super Org multi-tenancy, org-level ingestion tokens, and a round of Tantivy search performance work including a footer cache and bloom-filter pruning — sits just outside the recent window.
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.

OpenObserve is running a stabilization train on 0.91 while 0.92 gathers features in RC
◆ Current state
Two branches are moving at once. The 0.91 line has taken four patch releases since the start of July, each carrying two or three fixes — memtable rotation, RBAC migration for metric stream names, PagerDuty integration bugs, an anomaly-detection threshold that no longer forces a retrain. In parallel, 0.92 is accumulating in release candidates: agent-level filters, an option to disable default index fields via ZO_FEATURE_DEFAULT_INDEX_FIELDS_ENABLED, and parallel zstd compression. The substantive 0.91.0 release itself — Super Org multi-tenancy, org-level ingestion tokens, and a round of Tantivy search performance work including a footer cache and bloom-filter pruning — sits just outside the recent window.
◆ Where it's heading
The shape here is a project consolidating after a large release rather than chasing new surface area. The 0.92 RC contents point at operator control over ingest and index cost — letting users switch off default index fields is a storage-and-write-amplification lever, and parallel compression is the same concern from the CPU side. Agent-level filters suggest the collector-side story is being tightened too.
◆ Prediction
A 0.92.0 general release is the near-term move, carrying the index-field control and compression work, with the 0.91.x patch train tapering once it lands. Whether multi-tenancy from 0.91 gets follow-on quota or billing controls is not yet visible in the RC contents.

0.0ANALYTICS
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.
