Dagster vs NetObserv
A side-by-side editorial comparison of Dagster and NetObserv — release velocity, themes, recent moves, and the top alternatives to consider.
Dagster vs NetObserv: at a glance
What is Dagster?
Dagster is untangling itself from dbt-core so dbt Fusion can run without a fight.
Dagster's six most recent 1.13 releases are dominated by two threads. dagster-dbt no longer installs dbt-core, and a new extra installs dbt v2, the Fusion engine, with clear errors if the two are combined. The UI gained a phone layout covering Home, Jobs, Automation, Timeline, the Asset Catalog and run details. Dagster+ also added capacity-based alert policies, and agents can now retry code locations that fail to start.
What is NetObserv?
NetObserv hit 2.0 without breaking changes, then started renaming its metrics.
NetObserv's operator reached 2.0.0 in September, labelled entirely non-breaking: BGP ASN enrichment through FRRConfiguration CRDs, DNS names in metrics, DNS port configuration in the FlowCollector API, stricter RBAC and network policies for the operator itself, and TLS settings taken from the OpenShift API server. 2.0.1 was fixes and dependency bumps. 2.0.2 fixes ASN labels and IPSec metrics, captures OpenSSL socket tuples at event time in the eBPF agent, and renames filtered_flows_total to filtered_packets_total.

Dagster
5.0ANALYTICS
Dagster is untangling itself from dbt-core so dbt Fusion can run without a fight.
◆ Current state
Dagster's six most recent 1.13 releases are dominated by two threads. dagster-dbt no longer installs dbt-core, and a new extra installs dbt v2, the Fusion engine, with clear errors if the two are combined. The UI gained a phone layout covering Home, Jobs, Automation, Timeline, the Asset Catalog and run details. Dagster+ also added capacity-based alert policies, and agents can now retry code locations that fail to start.
◆ Where it's heading
The dbt work is a dependency reset with real consequences, because Fusion and dbt-core claim the same import namespace and overwrite each other silently. Dagster made the safe path the default and accepted a breaking change to do it. The rest of the window is operational hardening: resuming run workers on ECS, cross-account service discovery and clearer failure reasons when a run worker dies.
◆ Prediction
Weekly-style 1.13 releases should keep extending Fusion coverage in dagster-dbt, since metadata fetching there still degrades to warnings. Declarative Automation for jobs does not appear in these entries, so its exit from preview remains unconfirmed.
NetObserv
2.5ANALYTICS
NetObserv hit 2.0 without breaking changes, then started renaming its metrics.
◆ Current state
NetObserv's operator reached 2.0.0 in September, labelled entirely non-breaking: BGP ASN enrichment through FRRConfiguration CRDs, DNS names in metrics, DNS port configuration in the FlowCollector API, stricter RBAC and network policies for the operator itself, and TLS settings taken from the OpenShift API server. 2.0.1 was fixes and dependency bumps. 2.0.2 fixes ASN labels and IPSec metrics, captures OpenSSL socket tuples at event time in the eBPF agent, and renames filtered_flows_total to filtered_packets_total.
◆ Where it's heading
The 2.0 line adds routing context (BGP ASNs) and DNS identity to flows, which moves the tool from 'which pod talked to which' toward 'which network and service.' The operator's own security posture, with RBAC, network policies and TLS profiles, is getting as much attention as the data. The TLS thread continues inside the eBPF agent, with OpenSSL tracking narrowed to packet mode in 2.0.2.
◆ Prediction
Expect 2.0.x fixes around the new ASN and TLS enrichment, which both needed corrections in 2.0.2. The metric rename is a signal that dashboards built on older names may need updating in later releases too.
