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

Across 28 sampled AI answers from 4 engines, Saleor is recommended most often — appearing in 60.7% of recommendations, followed by Magento (57.1%) and Medusa (53.6%).
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 ecommerce platforms 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.
Buyer prompts in this window covered customization for mid-size retailers, avoiding platform fees, multi-currency and multi-warehouse needs, large catalogs, migration off a hosted platform, and headless versus monolithic builds. The recommendation leaders split by intent. Saleor led best_in_category at 81.3% of 16 runs and problem_solving at 100% of 8 runs. Magento led recommendation at 56.3% of 16 runs. WordPress led alternatives at 100% of 8 runs. Medusa led comparison at 62.5% of 8 runs, tied with Saleor at 62.5%.
Three of the five top products over-index on the same developer prompt about avoiding platform fees, so that prompt separates them less than the intent tables do. WooCommerce is the one that over-indexes on large catalogs. Only WordPress carries a published price in the snapshot, Personal at $9 a month with a free tier available, 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.

Saleor ranks first. It was recommended in 100% of the 8 runs on the prompt about a self-hosted solution for a developer who wants to avoid platform fees, and holds a recommendation share of 69.6% of 56 sampled answers in the 4-week window to 2026-09-05. Across its mentions it was recommended in 14 runs and listed in 25. Engine spread runs from Grok at 100% of Grok's 7 answers down to Claude at 42.9% of Claude's 7 answers.
Medusa ranks second, also recommended in 100% of the 8 runs on the developer prompt about avoiding platform fees, with an overall recommendation share of 64.3% (n = 56). It was recommended in 11 runs and listed in 25. Grok recommended it in 100% of 7 answers, Claude in 42.9% of 7.
Magento ranks third. It was recommended in 100% of the 8 runs on the prompt about a mid-size retailer wanting full customization, with an overall share of 58.9% (n = 56). Recommended in 15 runs, listed in 18. Grok sits highest at 85.7% of 7 answers, ChatGPT and Perplexity lowest at 42.9% of 14 answers each.
WordPress ranks fourth at 48.2% of 56 sampled answers, recommended in 9 runs and listed in 18. Grok recommended it in 85.7% of 7 answers, ChatGPT in 28.6% of 14. Personal is $9 a month with a free tier available, last verified 2026-09-05.
WooCommerce ranks fifth at 44.6% (n = 56), recommended in 7 runs and listed in 18. It was recommended in 87.5% of the 8 runs on the large product catalogs prompt. Claude, Gemini and Grok each sit at 57.1%, on 7, 14 and 7 answers; ChatGPT is lowest at 21.4% of 14 answers.
The five engines did not converge on one leader. Among the top five, Claude recommended Magento most across its 7 answers, and Gemini also led with Magento across its 14 answers. Grok led with Saleor across its 7 answers, ChatGPT with Saleor across its 14, and Perplexity with Saleor across its 14.
Saleor also carries the widest gap between engines. Claude recommended it in 42.9% of Claude's 7 answers; Grok recommended it in 100% of Grok's 7 answers. That is a spread of 57.1 points. Claude and Grok each contributed 7 runs in this window, the smallest engine samples of the five, so both ends of that gap rest on a narrow base.
This is the first measured window on record for open-source ecommerce platforms. It runs from 2026-08-08 to 2026-09-05 and covers 56 sampled answers across 5 engines. There is no prior window to compare against, so no entries, exits or share changes are reported yet.
Saleor leads it at a recommendation share of 69.6% of those 56 answers, followed by Medusa at 64.3% and Magento at 58.9%. WordPress sits at 48.2% and WooCommerce at 44.6%. Ranked products in the category number 47.
Engine coverage is uneven at the start. Gemini, ChatGPT and Perplexity each contributed 14 runs, Claude and Grok 7 each. A second window will give the first basis for movement.
