Shares here are read over the models both editions asked, so they can differ by a point or two from the standing above, which counts every model in this edition.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one is noise, and both are shown. Movement is read over the twelve models both editions asked; GPT-6 Luna, Muse Glimmer 30B joined this edition and are in the standing but not yet in the comparison.

Verbatim evidence the judge attached to positive labels.
“1. Couchbase - a key-value database that stores data as documents, ideal for simple data storage and retrieval needs.” Llama 4 Maverick · NoSQL · paraphrase prompt · first choice
“MongoDB and Couchbase are the best choices due to their ease of use, strong community support, and free tiers” Mistral Small · NoSQL · budget prompt · first choice
“Prefer managed services to keep ops headcount low: MongoDB Atlas, Amazon DynamoDB, Azure Cosmos DB, Couchbase Capella, managed Cassandra.” Muse Glimmer 30B · NoSQL · scale prompt · alternative
“Couchbase Capella is a strong alternative if performance and total cost of ownership (TCO) are paramount” Kimi K2 · NoSQL · direct prompt · alternative
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.
“otherwise it is usually more specialized than MongoDB for a general mid-market B2B stack” GPT-5.4 mini · NoSQL · direct prompt · soft negative
“Cons: Heavier operational complexity compared to fully managed alternatives” DeepSeek V4 Flash · NoSQL · paraphrase prompt · soft negative
“More enterprise-focused, $1,800+/mo — likely overkill for mid-market” DeepSeek V4 Flash · NoSQL · direct prompt · soft negative
“may be more complex and costly than traditional SQL databases” Mistral Small · NoSQL · negative prompt · soft negative
Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 94 of the 113 answers that named Couchbase and are not a share of its labels.
254 of the 296 domain citations in answers naming Couchbase came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read September 28, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Every page couchbase.com 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. Read September 29, 2026.
An email the morning each edition publishes: where this product moved, where it held, and by how much against the noise floor. One address, confirmed by a click; a stop link in every email.

What Couchbase's own pages state, read September 28, 2026: couchbase.com. A claimed page can correct any of them.
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.
A new claim receives the current edition's vendor brief for Couchbase by email, built from the raw record of the edition. It shows:
Couchbase is among the products AI models recommend first in NoSQL databases 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.
Badges read on light and dark pages. Alt text carries the claim, the category, the edition and the index, so it stays a citation where the image does not load.
