Every category where a model named Prometheus for a mid-market B2B company. Share is first choices across the direct, paraphrase, budget and scale prompts; rank is within every product named in that category.

Movement

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

“If you have strong engineering talent, investing time in open-source solutions like Prometheus + Grafana can provide excellent monitoring at minimal direct cost.” Claude Haiku 4.5 · Infra monitoring · budget prompt · first choice

“Safer Bets: Open-source like Prometheus/Grafana for control; avoid if you lack ops expertise.” Grok 4.1 Fast · Observability · negative prompt · first choice

“Grafana + Prometheus + Loki + Tempo (or Mimir) is the enterprise favorite” DeepSeek V4 Flash · Infra monitoring · negative prompt · first choice

“For Kubernetes & Microservices: Start with Prometheus + Grafana.” Qwen 3.7 Flash · Infra 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.

“prefer tools with native Kubernetes support ... (e.g., Prometheus or New Relic's K8s integration)" but "Setting up, securing, and scaling a self-hosted Prometheus/Grafana cluster"” Qwen 3.7 Flash · Infra monitoring · negative prompt · soft negative

“open-source Prometheus and Grafana are only "free" if you don't calculate the engineering hours spent building, updating, and hosting them” Gemini 3.5 Flash · Infra monitoring · direct prompt · soft negative

“While platforms like raw Prometheus + Grafana are popular, using them as a "black box" solution is a trap for many organizations.” Qwen 3.7 Flash · Observability · negative prompt · soft negative

“rarely have a dozen dedicated SREs to spend their days maintaining open-source infrastructure (like vanilla Prometheus and Thanos)” Gemini 3.5 Flash · Observability · direct prompt · soft negative

Named alongside

A head-to-head page exists where both products are in a category's top three. 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 Prometheus. 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 80 of the 107 answers that named Prometheus 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 Prometheus'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 Prometheus, 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 prometheus.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.
