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.

What the models said for it
Verbatim evidence the judge attached to positive labels.
“Sentry: The market leader. Incredibly rich features, massive integration ecosystem, open-source roots (with a self-hosted option), and strong session replay” Gemini 3.5 Flash · Error monitoring · scale prompt · first choice
“Sentry | Overall Gold Standard (Full-Stack & Observability) | Unrivaled SDK support, native Session Replay, and robust security posture.” Gemini 3.5 Flash · Error monitoring · paraphrase prompt · first choice
“Sentry remains the default all-around choice for most SaaS product teams and is the market leader for developer-first error tracking” Muse Glimmer 30B · Error monitoring · direct prompt · first choice
“Sentry is the default for most teams because it's broad, fast to set up, and excels at stack traces and issue grouping.” GLM 4.7 FlashX · Error monitoring · comparative 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.
“Users report "the price is a lot with hidden fees"” MiniMax M2.5 · Uptime monitoring · negative prompt · hard negative
“Recent CVE tracking shows active issues in the Sentry stack... That is not a reason to avoid Sentry, but it illustrates why patch velocity... are listed as evaluation criteria” Muse Glimmer 30B · Error monitoring · negative prompt · soft negative
“Sentry, for example, offers configurable scrubbing, but you need to verify the settings and test what actually gets removed” GPT-6 Luna · Error monitoring · negative prompt · soft negative
“you should exercise extreme caution if you plan on self-hosting it... massive, distributed microservices stack” Gemini 3.5 Flash · Error monitoring · 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 Sentry. 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 269 of the 303 answers that named Sentry and are not a share of its labels.

How it is countedHide how it is counted
Every page sentry.io 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. Of its titles that name a category, most name feature flags (54); 6 name its categories the models place it in. 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.

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 Sentry'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 Sentry, 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 Sentry by email, built from the raw record of the edition. It shows:
- where Sentry 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 Sentry, 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.
