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 17, 2026
Sample: 28 AI answers · Window: Aug 20, 2026 – Sep 17, 2026 (4-week rolling) · trend vs prior 4 weeks (98 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)

Across 28 sampled AI answers from 4 engines, Moodle is recommended most often — appearing in 85.7% of recommendations, followed by Open edX (46.4%) and edX (46.4%).
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 self-hosted learning management systems and sampled 28 answers between Aug 20, 2026 and Sep 17, 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.
Seven prompt types were sampled, and the leaders split by what the buyer asked. Moodle led recommendation prompts at 94.4% of 18 runs in the 4-week window to 2026-09-05, and problem_solving prompts at 100% of 9 runs, the set that includes SCORM content and progress tracking. Open edX and edX both led best_in_category at 94.4% of 18 runs, the pair of prompts covering corporate training at 500 employees and on-premise university data. Canvas, Open edX and edX all reached 100% of the 9 alternatives runs. Moodle led the comparison prompt at 55.6% of 9 runs. So the shortlist depends on whether the deployment question is a data-residency one, a scale one, or a cost-versus-control one. No pricing fact was verified for any of the five, so the measured answers say nothing about cost here. The verified facts on record are feature and integration details, last verified 2026-09-05.

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.

Moodle is recommended most often for the prompt "best open-source LMS for a university that wants to keep student data on-premise", at 100% of the 9 answers to that prompt. Across the category it holds a recommendation share of 87.3% of 63 sampled answers in the 4-week window to 2026-09-05, with 40 answers recommending it and 15 listing it. Gemini recommended it in 100% of its 14 answers; Claude in 42.9% of its 7 answers.
edX is also recommended for the on-premise university prompt, at 100% of those 9 answers. Its overall recommendation share is 60.3% (n = 63), split 27 recommended and 11 listed, with 1 answer warning against it. Gemini and Grok sit highest at 71.4% of Gemini's 14 answers and 71.4% of Grok's 7 answers; ChatGPT lowest at 52.4% of its 21 answers.
Open edX matches that pattern, recommended in 100% of the 9 answers to the on-premise university prompt and 60.3% of 63 answers overall, with 27 recommended and 11 listed. Gemini at 71.4% of 14 answers stands highest, ChatGPT at 52.4% of 21 answers lowest. Open edX supports self-paced learning and XBlock integration.
Canvas leads the prompt "open-source LMS alternatives to expensive enterprise learning platforms", recommended in 100% of those 9 answers. Overall it holds 38.1% of 63 answers, with 12 recommended and 12 listed. Grok reached 57.1% of its 7 answers; Claude and Gemini both 28.6%, of 7 and 14 answers.
Chamilo is recommended for the same alternatives prompt, at 100% of 9 answers, and 38.1% of 63 answers overall. The split leans to mentions, with 17 listed against 7 recommended. Grok highest at 71.4% of its 7 answers, ChatGPT lowest at 19% of its 21 answers.
Four of the five engines recommended Moodle most among the top five: Gemini across 14 answers, Grok across 7 answers, ChatGPT across 21 answers, and Perplexity across 14 answers. Claude was the exception, recommending edX most among the top five across its 7 answers.
Moodle carries the widest gap between engines. It was recommended in 42.9% of Claude's 7 answers and 100% of Gemini's 14 answers, a spread of 57.1 points. Claude's run count is the smallest in the set at 7, so that low end rests on few answers. The other four products moved less between engines, with Chamilo ranging from 19% of ChatGPT's 21 answers to 71.4% of Grok's 7 answers.
This is the first measured window on record for self-hosted learning management systems. It runs 2026-08-08 to 2026-09-05, 28 days, and covers 63 sampled answers across 5 engines. There is no prior window to compare against, so no entries, exits or share changes are recorded yet.
As the window stands, Moodle leads on recommendation share at 87.3% of 63 answers, and was the first product recommended in 29 of those answers, a first-recommendation rate of 52.7%. edX and Open edX follow, both at 60.3% of 63 answers. Canvas and Chamilo both sit at 38.1% of 63 answers. Moodle is the leader for Gemini, Grok, ChatGPT and Perplexity; edX leads for Claude. The next window will give the first comparison point.
