Every category where a model named OpenMetadata for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

This is the first edition on this tier, so no move can be computed for OpenMetadata 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 OpenMetadata 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.

“OpenMetadata is generally the better starting point due to its simpler stack and faster time-to-value.” MiniMax M2.5 · Data catalogs · budget prompt · first choice

“OpenMetadata (Best Overall Open Source) ... this is widely considered the best open-source data catalog” GLM 4.7 FlashX · Data catalogs · budget prompt · first choice

“The Best All-Around (Open Source): OpenMetadata ... this is currently the top contender.” Qwen 3.7 Flash · Data catalogs · budget prompt · first choice

“If you have some technical resources, OpenMetadata or DataHub are the best free options.” Mistral Small · 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.

“While open source options like OpenMetadata and DataHub are credible, they require substantial in-house engineering expertise to deploy, maintain, and scale.” Mistral Small · Data catalogs · negative prompt · soft negative

“Only choose this if you have a dedicated data platform engineer who has the bandwidth to manage and upgrade the infrastructure.” Gemini 3.5 Flash · Data catalogs · scale prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named OpenMetadata. 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 88 of the 94 answers that named OpenMetadata and are not a share of its labels.

How it is countedHide how it is counted

Every page open-metadata.org exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person. Read October 5, 2026.

Names read as OpenMetadata

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

Is this your product?

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 OpenMetadata'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 OpenMetadata, 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 OpenMetadata by email, built from the raw record of the edition. It shows:

where OpenMetadata 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 OpenMetadata, 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.

Badges

Wins only: a badge exists where OpenMetadata is ranked in a category's top three this edition. Three sizes, one file each, light and dark; the code is under each.

ShowHide

OpenMetadata is among the products AI models recommend first in Data catalogs and governance this edition. Each badge says so in the buyer's words, names the edition, and links to the standing. The next edition issues a new badge; this one stays true as a record of October 2026.
