Movement

This is the first edition on this tier, so no move can be computed for Amundsen yet. From the next edition this section shows, per buyer segment and per category, whether its share moved by more than the measured noise floor.

By model

How each model treated Amundsen across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“likely to be an open-source tool such as Amundsen or DataHub, which are suitable for on-premise environments” Llama 4 Maverick · Data catalogs · budget prompt · first choice

“Best ultra-lean choice: Amundsen” GPT-5.4 mini · Data catalogs · budget prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Avoid for Mid-Market: ... open-source like DataHub/Amundsen (free but needs engineering overhead)” Grok 4.1 Fast · Data catalogs · direct prompt · hard negative

“Amundsen (Lyft) — archived and no longer maintained as of 2026, so don't build on it” DeepSeek V4 Flash · Data catalogs · budget prompt · hard negative

“have lower license costs but require significant DevOps effort to install, maintain, and keep running” Qwen 3.7 Flash · Data catalogs · scale prompt · soft negative

“Who to be cautious with: Amundsen (in its raw form), Hive Metastore (used as a primary catalog).” Qwen 3.7 Flash · Data catalogs · negative prompt · soft negative

A head-to-head page exists where both products are among a category's top eight. The other rows are the same fact without a page behind them, so they link to the product instead.

What carried it into the answer

The sites and pages cited by the answers that named Amundsen. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 28 of the 34 answers that named Amundsen and are not a share of its labels.

Names read as Amundsen

What the judge wrote, as written, with how often. The vendor table decides that these count as Amundsen; a claim can dispute any of them.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Amundsen's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Amundsen, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

What a new claim receivesHide what a new claim receives

A new claim receives the current edition's vendor brief for Amundsen by email, built from the raw record of the edition. It shows:

where Amundsen is named, by buyer and by framing, and which cells hold its first choices;
the claims the models make when they name it, ranked, with the strongest and the weakest quoted;
its vocabulary against the segment leader's, and the pages the models cited;
who was chosen in the answers that did not name Amundsen, and every reason the record gives;
a battlecard for each top rival: the head-to-head split, why they win, and the reservation quoted against them;
one page of published figures cleared to show a buyer.
