What AI assistants actually recommend when buyers ask about open-source data pipeline 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 (72 answers)
Samples by engine: GEMINI 7 (last run Sep 5, 2026) · CHATGPT 7 (last run Sep 5, 2026) · CLAUDE 7 (last run Sep 6, 2026) · PERPLEXITY 7 (last run Sep 5, 2026) · GROK 0 (last run Aug 15, 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, Airbyte is recommended most often — appearing in 75% of recommendations, followed by Meltano (64.3%) and Airflow (60.7%).
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 data pipeline 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.

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.
Independence: Orbator customers are badged for disclosure. Customer status does not affect prompts, sampling, extraction, or ranking — see the methodology. Your product on this list? Claim it to see the prompts behind your rank and track it weekly.
