Movement

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

“Sentry is the most feature‑rich, open‑source‑friendly platform, offering error tracking, APM, session replay, profiling, and uptime monitoring in one place.” GLM 4.7 FlashX · Error monitoring · comparative prompt · first choice
“Sentry | Purpose-built error tracking, broadest language/mobile coverage, great grouping, generous free tier | Event-based pricing can scale up” DeepSeek V4 Flash · Error monitoring · scale prompt · first choice
“Sentry: The gold standard for developer experience. Very strong on source maps and mobile. Pricing can get expensive at very high volumes.” Qwen 3.7 Flash · Error monitoring · scale prompt · first choice
“Choose Sentry if you want the most complete platform — error tracking, performance, session replay, and release context in one tool” DeepSeek V4 Flash · 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.

“Avoid Sentry if you require deep Application Performance Monitoring (APM)” Mistral Small · Error monitoring · negative prompt · hard negative
“Sentry if you expect noisy error storms and do not want usage-based surprise costs; it is repeatedly described as the default choice, but with explicit warnings about per-event billing.” Perplexity Sonar · Error monitoring · negative prompt · soft negative
“Sentry is not ideal for teams that need deep APM with automatic N+1 detection or flat-rate pricing that doesn't scale with error volume.” Llama 4 Maverick · Error monitoring · negative prompt · soft negative
“Frequently praised as the best overall error tracker, but its event-based pricing is a recurring source of surprise invoices.” DeepSeek V4 Flash · Error monitoring · negative prompt · soft negative

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, four of the twelve in this edition, so these counts come from 202 of the 269 answers that named Sentry 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 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.

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 sentry.io 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.
