Grafana Loki vs OpenObserve: at a glance
What is Grafana Loki?
Loki 4.0 RC strips out legacy storage backends and the simple scalable mode.
Loki 4.0.0-rc.2 is out, the first major-version candidate in the feed. It removes the BoltDB, Cassandra, DynamoDB, BigTable and gRPC storage backends, drops Simple Scalable Deployment targets, defaults to Thanos storage clients and adds label-based access control. The Operator had prepared for this: 0.12 already made storage schemas explicit and stopped reconciling deprecated BoltDB schemas.
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.

Grafana Loki
6.3ANALYTICS
Loki 4.0 RC strips out legacy storage backends and the simple scalable mode.
◆ Current state
Loki 4.0.0-rc.2 is out, the first major-version candidate in the feed. It removes the BoltDB, Cassandra, DynamoDB, BigTable and gRPC storage backends, drops Simple Scalable Deployment targets, defaults to Thanos storage clients and adds label-based access control. The Operator had prepared for this: 0.12 already made storage schemas explicit and stopped reconciling deprecated BoltDB schemas.
◆ Where it's heading
Loki is narrowing to one storage path, TSDB on object storage, and cutting configuration it has carried for years. Query-tee changes and the unplugged V2 engine show the query layer is also being reworked. Operators on older backends or SSD layouts face a real migration.
◆ Prediction
More 4.0 release candidates are likely before a final 4.0.0, followed by a Helm chart and Operator release aligned to it.
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.
