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?
Dovetail lets admins choose which connectors members can plug into the workspace.
Channels 2.0 reached general availability on October 21. In November Dovetail opened itself to outside assistants: Claude and ChatGPT can co-author docs, agents can be managed from MCP clients such as Claude and Cursor, and Jira roadmap items can pull in Dovetail evidence. On November 12 it added the matching control: workspace admins decide which connectors members may use.

◆ 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
Dovetail lets admins choose which connectors members can plug into the workspace.
◆ Current state
Channels 2.0 reached general availability on October 21. In November Dovetail opened itself to outside assistants: Claude and ChatGPT can co-author docs, agents can be managed from MCP clients such as Claude and Cursor, and Jira roadmap items can pull in Dovetail evidence. On November 12 it added the matching control: workspace admins decide which connectors members may use.
◆ Where it's heading
Dovetail is turning its research repository into a source that other tools and assistants read and write, rather than a place people must visit. The admin connector controls show the cost of that openness: each new integration needs a security gate before larger customers will turn it on.
◆ Prediction
With connectors now gated by admins, expect more connectors and MCP actions to ship behind the same controls, plus audit detail on what connected tools did.
