Cortex vs Kubecost
A side-by-side editorial comparison of Cortex and Kubecost — release velocity, themes, recent moves, and the top alternatives to consider.
Cortex vs Kubecost: 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 Kubecost?
Kubecost cuts three 3.3.2 release candidates in two days, still without notes.
Kubecost opened the 3.3.2 patch line on November 11 and tagged rc.1 through rc.3 by November 13. Each is an automated in-code version bump with no described changes, as with every tag since October, when the 3.3.1 and 3.2.5 candidates went out the same way.

◆ 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.
Kubecost
5.0ANALYTICS
Kubecost cuts three 3.3.2 release candidates in two days, still without notes.
◆ Current state
Kubecost opened the 3.3.2 patch line on November 11 and tagged rc.1 through rc.3 by November 13. Each is an automated in-code version bump with no described changes, as with every tag since October, when the 3.3.1 and 3.2.5 candidates went out the same way.
◆ Where it's heading
The quick run of candidates suggests 3.3.2 is close to a final tag. The public tags still say nothing about what the patch fixes.
◆ Prediction
Expect a 3.3.2 final tag within days; what it changes will not be visible from these release notes.
