Cortex vs Dovetail
A side-by-side editorial comparison of Cortex and Dovetail — release velocity, themes, recent moves, and the top alternatives to consider.
Cortex vs Dovetail: 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 Dovetail?
Channels 2.0 is now the default, and Dovetail is pulling feedback sources up a level.
Channels 2.0 reached general availability on October 21 as the standard Channels experience for every Dovetail customer, after a closed beta in July and an open beta in September. Each idea now has an activity log, and saved views open with a snapshot of ideas, evidence, sources and top activity. Sources entered beta, aimed at the per-project integration setup that teams had to repeat. Chat now opens beside work, and default contact fields address the mapping that CRM sync and revenue rollups depend on.

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.
Dovetail
5.0ANALYTICS
Channels 2.0 is now the default, and Dovetail is pulling feedback sources up a level.
◆ Current state
Channels 2.0 reached general availability on October 21 as the standard Channels experience for every Dovetail customer, after a closed beta in July and an open beta in September. Each idea now has an activity log, and saved views open with a snapshot of ideas, evidence, sources and top activity. Sources entered beta, aimed at the per-project integration setup that teams had to repeat. Chat now opens beside work, and default contact fields address the mapping that CRM sync and revenue rollups depend on.
◆ Where it's heading
With GA done, attention has moved from what an idea is to what feeds it and who can trust it. Sources makes data connection an account-level concern, and default fields remove a setup step in front of revenue rollups. Activity logs and snapshots add the accountability a roadmap discussion needs. Each change pulls Dovetail toward a shared system for product teams, away from a project-by-project research tool.
◆ Prediction
Sources leaving beta is the next visible milestone, given how much of the October work depends on connected data. Status flowing back from Jira or Linear remains absent from the entries.
