Movement

This is the first edition on this tier, so no move can be computed for HAProxy 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 HAProxy across every prompt where it was named for a mid-market B2B company. Fourteen models, six prompts per category.

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.

“If you have standard web apps or APIs: Go with HAProxy. It has the broadest adoption, most documentation, and best performance for the price (free).” Kimi K2 · Load balancers · budget prompt · first choice
“The performance leader — handles millions of requests per second with sub-millisecond latency... HAProxy is the performance benchmark.” DeepSeek V4 Flash · Load balancers · comparative prompt · first choice
“Fastest and most stable - used by GitHub, Reddit, Stack Overflow ... High-performance, mission-critical | HAProxy” Kimi K2 · Load balancers · comparative prompt · first choice
“My default recommendation is HAProxy Enterprise if you need an ADC that works across on-premises and cloud environments.” GPT-6 Luna · Load balancers · paraphrase 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.

“Open‑source solutions that are no longer actively maintained (e.g., very old versions of HAProxy, Nginx...) | Unpatched CVEs” GLM 4.7 FlashX · Load balancers · negative prompt · soft negative
“consider a third-party option like F5 or HAProxy, but that adds more ops overhead” GPT-5.4 mini · Load balancers · direct prompt · soft negative
“running them on under-powered virtual machines (like a $5/mo VPS) creates a bottleneck” Qwen 3.7 Flash · Load balancers · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named HAProxy. 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 140 of the 174 answers that named HAProxy and are not a share of its labels.

Search figures are US estimates from DataForSEO, read October 5, 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.

How it is countedHide how it is counted

Every page haproxy.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 September 29, 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 HAProxy'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 HAProxy, 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 HAProxy by email, built from the raw record of the edition. It shows:

  • where HAProxy 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 HAProxy, 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.
The subscriber app

A verification link goes to your work email; an address at haproxy.com is approved on the spot, any other is reviewed by hand. Your email is never published. Claiming gives no say over labels, shares, verdicts or which quotes appear.
