Movement

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

By model

How each model treated Couchbase across every prompt where it was named for a mid-market B2B company. Twelve 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.

“Couchbase Capella delivers the best combination of performance, total cost of ownership, multicloud flexibility, and enterprise features” GLM 4.7 FlashX · NoSQL · direct prompt · first choice

“Couchbase Server Community Edition is the best budget-friendly baseline because it is free” Perplexity Sonar · NoSQL · budget prompt · first choice

“MongoDB and Couchbase are the most popular choices for document workloads” GLM 4.7 FlashX · NoSQL · budget prompt · first choice

“MongoDB or Couchbase would be safe bets for most mid-market B2B use cases” MiniMax M2.5 · NoSQL · direct 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.

“Risk Level: Medium Couchbase generally has better security than MongoDB or Redis, but it still suffers from common "Insecure Defaults."” GLM 4.7 FlashX · NoSQL · negative prompt · soft negative

“It's more operational overhead, so it's usually for specialized real-time workloads rather than a general B2B default.” DeepSeek V4 Flash · NoSQL · paraphrase prompt · soft negative

“it can struggle with complex queries and joins, making it less ideal for OLAP” Mistral Small · NoSQL · negative prompt · soft negative

What carried it into the answer

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

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 77 of the 101 answers that named Couchbase and are not a share of its labels.

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 Couchbase'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 Couchbase, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at couchbase.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
