Movement

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

“TDengine — Purpose-built for IoT, better scale performance” Kimi K2 · Time series DBs · negative prompt · alternative

“Industrial IoT fleet management at the edge? → TDengine” DeepSeek V4 Flash · Time series DBs · comparative prompt · alternative

“or TDengine for IoT‑heavy workloads” GLM 4.7 FlashX · Time series DBs · budget prompt · alternative

“For Industrial/Edge-Focused: TDengine” Kimi K2 · Time series DBs · paraphrase prompt · alternative

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.

“community is tiny outside of China; AGPL license” DeepSeek V4 Flash · Time series DBs · negative prompt · soft negative

“Patch or migrate: TDengine (CVE-2026-42542)” GLM 4.7 FlashX · Time series DBs · negative prompt · soft negative

“AGPL is copyleft e.g. TDengine” Muse Glimmer 30B · Time series DBs · budget prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named TDengine. 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 32 of the 33 answers that named TDengine and are not a share of its labels.

How it is countedHide how it is counted

Every page tdengine.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. 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.

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

where TDengine 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 TDengine, 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.
