OpenReplay vs Zipkin: at a glance
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.
What is Zipkin?
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.

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.
Zipkin
0.0ANALYTICS
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
◆ Current state
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.
◆ Where it's heading
This is a project in preservation rather than development. The pattern across the window — feature in May 2024, then three releases of purely defensive dependency work, then silence since January 2025 — describes a mature tracing server being kept safe to run rather than extended. The distributed-tracing work that would once have landed here now largely happens in OpenTelemetry, which Zipkin interoperates with rather than competes against.
◆ Prediction
The feed has produced nothing for nineteen months, so the honest read is that no next release is scheduled. If one comes, the shape of the last three says it will be another dependency and base-image refresh rather than new capability.
