What AI assistants actually recommend when buyers ask about open-source log management tools — measured on a rolling 4-week window across 4 engines, published as open data.
Updated 2026-09-18 · 28 sampled answers · rolling 4-week window · methodology
Rankings are measured from sampled AI answers — never editorial, never paid. Orbator builds AI-visibility tooling; when Orbator itself appears in any category, it is measured by the same rules as everyone else.
Measured by Orbatormethodology owner Henrik Tellewindow ends Sep 18, 2026
Sample: 28 AI answers · Window: Aug 21, 2026 – Sep 18, 2026 (4-week rolling) · trend vs prior 4 weeks (98 answers)
Samples by engine: GEMINI 7 (last run Sep 6, 2026) · CHATGPT 7 (last run Sep 6, 2026) · CLAUDE 7 (last run Sep 7, 2026) · PERPLEXITY 7 (last run Sep 6, 2026) · GROK 0 (last run Aug 18, 2026 — stalest)
How these numbers are made: sampling design · prompt provenance · what counts as a mention · what we cannot see

Across 28 sampled AI answers from 4 engines, Grafana is recommended most often — appearing in 85.7% of recommendations, followed by Loki (82.1%) and Graylog (71.4%).
This is a measurement of share of voice across 4 AI engines — not an editorial pick. See the full ranking below.
Orbator asked Gemini, ChatGPT, Claude and Perplexity buyer questions about open-source log management tools and sampled 28 answers between Aug 21, 2026 and Sep 18, 2026. Recommendation share counts the answers that recommended or listed a product, so a passing mention or a warning adds nothing to it. A category publishes once it holds at least 20 independently sampled answers in the window. Read the full methodology or download this ranking as CSV.
The seven sampled prompts split into five intents, and the leaders differ by intent. Loki was recommended in 100% of the 12 best_in_category runs. Grafana and Loki each led the 12 recommendation runs at 83.3%. In the 6 alternatives runs and the 6 comparison runs, Grafana, Graylog and Loki each sat at 83.3%. The 6 problem_solving runs, which cover pipelines handling millions of events per day, went to OpenSearch at 100%.
So the shortlist depends on the question being asked. A buyer framing the decision as pick-one for a small DevOps team lands on a different set than one framing it as scale engineering. Engine agreement also varies. Graylog ran from 35.7% of ChatGPT's 14 answers to 100% of Gemini's 7 answers in the 4-week window to 2026-09-05. No pricing fact is recorded for any of the five, so cost has to be checked at source.

Reading the numbers: Share is a point estimate on 28 sampled answers, so each row also shows its 95% CI — the Wilson score interval around that share. When two products' intervals overlap, the gap between them isn't statistically meaningful at this sample size. First pick is the share of a product's recommending answers where it was named first, which separates “always mentioned” from “usually the top recommendation”. Full methodology.

Loki was recommended in 85.7% of 42 sampled answers in the 4-week window to 2026-09-05, and was first recommendation in 50% of runs. Its mention breakdown splits into 25 recommended and 11 listed. Engine spread runs from 100% of Gemini's 7 answers, Grok's 7 and Perplexity's 7, down to 64.3% of ChatGPT's 14 answers.
Grafana was recommended in 83.3% of 42 sampled answers in the same window, with a first recommendation rate of 37.1%. The breakdown is 24 recommended against 11 listed. Highest engine share was 100% of Gemini's 7 answers, matched by Grok and Perplexity at 7 runs each; lowest was 64.3% of ChatGPT's 14 answers.
Kubernetes was recommended in 66.7% of 42 sampled answers, with 20 recommended and 8 listed. It ran from 100% of Gemini's 7 answers and Grok's 7 answers down to 42.9% of Perplexity's 7 answers. Its published feature fact is automated rollouts and rollbacks, last verified 2026-09-05.
OpenSearch was recommended in 66.7% of 42 sampled answers and led the problem_solving intent at 100% of 6 runs. Its breakdown is 16 recommended, 12 listed, 2 warned against. Highest was 100% of Grok's 7 answers, lowest 42.9% of Claude's 7 answers.
Graylog was recommended in 66.7% of 42 sampled answers, with 11 recommended and 17 listed, the only top-five product listed more often than recommended. It reached 100% of Gemini's 7 answers and 35.7% of ChatGPT's 14 answers.
Four of the five engines recommended the same product most among the top five. Loki led for Claude across 7 answers, for Gemini across 7 answers, for Grok across 7 answers and for Perplexity across 7 answers. ChatGPT was the exception, with OpenSearch leading among the top five across its 14 answers.
The widest gap between engines belongs to Graylog. It was recommended in 35.7% of ChatGPT's 14 answers and in 100% of Gemini's 7 answers, a spread of 64.3 points. Kubernetes also moved a long way across engines, from 42.9% of Perplexity's 7 answers to 100% of Gemini's 7 answers. Loki and Grafana were the steadiest of the five, each sitting at 100% on three engines and 64.3% of ChatGPT's 14 answers.
This is the first measured window on record for open-source log management tools. It runs 2026-08-08 to 2026-09-05, 28 days, on 42 sampled answers across 45 ranked products and five engines. There is no prior window to compare against, so no product entered or left the top ten and no share change can be reported yet.
Loki leads the first window, recommended in 85.7% of those 42 answers and first recommendation in 50% of runs. Grafana follows at 83.3% of 42. Kubernetes, OpenSearch and Graylog all sit at 66.7% of 42, separated in this snapshot only by how often they were listed rather than recommended and by average position, which ranges from 3 for Kubernetes to 6.7 for Graylog. The next window will show which of those holds.
