OpenObserve vs Zipkin
A side-by-side editorial comparison of OpenObserve and Zipkin — release velocity, themes, recent moves, and the top alternatives to consider.
OpenObserve vs Zipkin: at a glance
What is OpenObserve?
OpenObserve 1.2.0-rc1 opens a metrics v2 cycle with chart alerts and forecasts.
OpenObserve opened its 1.2 cycle with v1.2.0-rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. The rest is fixes: PromQL result-cache alignment, a switch back to the upstream promql-parser, and alert dedup state keyed by org. The 1.1 line before it was memory-bounded caches, PromQL quantile speedups and backport patches.
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.

OpenObserve
5.0ANALYTICS
OpenObserve 1.2.0-rc1 opens a metrics v2 cycle with chart alerts and forecasts.
◆ Current state
OpenObserve opened its 1.2 cycle with v1.2.0-rc1, led by metrics v2: alerts created from charts, comparisons, forecasts, formulas and Prometheus 3.x functions. The rest is fixes: PromQL result-cache alignment, a switch back to the upstream promql-parser, and alert dedup state keyed by org. The 1.1 line before it was memory-bounded caches, PromQL quantile speedups and backport patches.
◆ Where it's heading
After a release cycle spent on metrics storage internals, OpenObserve is now building user-facing metrics features on top. The direction is toward a Prometheus-compatible metrics experience that competes on analysis, not just ingestion cost.
◆ Prediction
Expect further 1.2 release candidates with fixes before a stable 1.2.0, following the three-RC pattern of 1.1.
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.
