Cortex vs Apache SkyWalking
A side-by-side editorial comparison of Cortex and Apache SkyWalking — release velocity, themes, recent moves, and the top alternatives to consider.
Cortex vs Apache SkyWalking: at a glance
What is Cortex?
Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.
What is Apache SkyWalking?
SkyWalking 11.1 builds service maps from OpenTelemetry traces, no SkyWalking agent required.
Apache SkyWalking spent 2025 and 2026 rebuilding its foundations: BanyanDB replaced H2, the Groovy DSL runtime gave way to ANTLR4 and Javassist, and 11.0.0 split the UI out of the backend. Version 11.1.0, released November 6, stores OTLP traces as they arrive and adds a Trace Analysis Language that turns spans into service, instance and endpoint metrics, topology and dashboards for the databases, caches and queues those services call. Applications instrumented only with OpenTelemetry SDKs now get SkyWalking's dashboards without its agent.

Cortex
2.5ANALYTICS
Cortex 1.22 is on its fourth candidate, with sharded Parquet and years of deprecated flags removed.
◆ Current state
Cortex 1.22.0 has been in release candidates since 12 September, reaching rc.3 on 6 October, and GitHub shows no final yet. The candidate adds sharded Parquet conversion and querying, resource-based query eviction that cancels the heaviest query when CPU or heap crosses a threshold, OCI Object Storage as a backend, and an active-series tracker per tenant. It also removes long-deprecated flags and config fields, some of which now stop Cortex from starting if left in place.
◆ Where it's heading
The storage arc toward Parquet continues: after 1.21 made Parquet a Store Gateway query mode, 1.22 shards files that exceed column limits. A second arc is protecting shared clusters from heavy tenants, through query eviction, resource-based throttling and concurrent data-byte limits on store gateways. The cleanup is the maturity arc from 1.21 carried further: no-op flags that were tolerated for releases now fail at startup.
◆ Prediction
1.22.0 final should follow rc.3, which added only two fixes. Operators should expect upgrade failures from leftover deprecated flags, and the release notes tell them to grep runtime configs before upgrading.

3.8ANALYTICS
SkyWalking 11.1 builds service maps from OpenTelemetry traces, no SkyWalking agent required.
◆ Current state
Apache SkyWalking spent 2025 and 2026 rebuilding its foundations: BanyanDB replaced H2, the Groovy DSL runtime gave way to ANTLR4 and Javassist, and 11.0.0 split the UI out of the backend. Version 11.1.0, released November 6, stores OTLP traces as they arrive and adds a Trace Analysis Language that turns spans into service, instance and endpoint metrics, topology and dashboards for the databases, caches and queues those services call. Applications instrumented only with OpenTelemetry SDKs now get SkyWalking's dashboards without its agent.
◆ Where it's heading
After taking storage and runtime in-house, SkyWalking is opening its front door to OpenTelemetry data. Its value is shifting from its own agents toward the analysis it runs on any trace source.
◆ Prediction
Expect more TAL coverage and OpenTelemetry quick starts, with SkyWalking's own agents positioned as optional rather than required.
