OpenReplay vs Apache Storm: at a glance
What is OpenReplay?
OpenReplay's feed is Helm chart bumps behind its asset-cacher deny list.
OpenReplay's entries since November 4 are automated backup tags on the 1.26 and 1.27 lines that only increment Helm chart versions for chalice, assist-api and assist-stats. The last functional change remains the November 3 ASSETS_DENY_HOSTS option, which lets self-hosters block hosts the asset cacher may fetch, alongside a fix for EE 1.26 images that crashed on start.
What is Apache Storm?
Storm 3.1 adds an Iceberg sink and closes a long list of security gaps in Nimbus and the UI.
Storm runs a 3.x line, started in July with 3.0.0's removal of all Clojure and a Java 21 baseline, alongside 2.8.x maintenance. 3.1.0 on September 12 adds a storm-iceberg module with an Apache Iceberg sink bolt and a setting to control JSONP wrapping, and spends most of its notes on hardening: log listings filtered by user permission, jar locations restricted to the Nimbus inbox, blobstore names confined to topology directories, TLS peer verification for worker connections and required Kryo class registration.

OpenReplay
5.0ANALYTICS
OpenReplay's feed is Helm chart bumps behind its asset-cacher deny list.
◆ Current state
OpenReplay's entries since November 4 are automated backup tags on the 1.26 and 1.27 lines that only increment Helm chart versions for chalice, assist-api and assist-stats. The last functional change remains the November 3 ASSETS_DENY_HOSTS option, which lets self-hosters block hosts the asset cacher may fetch, alongside a fix for EE 1.26 images that crashed on start.
◆ Where it's heading
The project is in a maintenance stretch, backporting fixes across 1.25 to 1.27 and repackaging charts. Nothing in recent entries points to new user-facing features.
◆ Prediction
Unclear from these entries; more chart-bump backup tags are likely until a 1.27.x release with notes appears.
Apache Storm
0.0ANALYTICS
Storm 3.1 adds an Iceberg sink and closes a long list of security gaps in Nimbus and the UI.
◆ Current state
Storm runs a 3.x line, started in July with 3.0.0's removal of all Clojure and a Java 21 baseline, alongside 2.8.x maintenance. 3.1.0 on September 12 adds a storm-iceberg module with an Apache Iceberg sink bolt and a setting to control JSONP wrapping, and spends most of its notes on hardening: log listings filtered by user permission, jar locations restricted to the Nimbus inbox, blobstore names confined to topology directories, TLS peer verification for worker connections and required Kryo class registration.
◆ Where it's heading
After the 2.8.6 and 2.8.7 CVE releases, the 3.x line is closing access-control gaps across Nimbus, the logviewer and worker transport. The Iceberg sink adds a direct path into lakehouse storage.
◆ Prediction
Expect 3.1.x follow-ups, possibly with security advisories for the hardened paths, and continued 2.8.x maintenance; whether more lakehouse connectors follow is unclear.
