Updated 2026-09-17 · 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 17, 2026
Sample: 28 AI answers · Window: Aug 20, 2026 – Sep 17, 2026 (4-week rolling) · trend vs prior 4 weeks (91 answers)
Samples by engine: GEMINI 7 (last run Sep 8, 2026) · CHATGPT 7 (last run Sep 8, 2026) · CLAUDE 7 (last run Aug 21, 2026) · PERPLEXITY 7 (last run Sep 8, 2026) · GROK 0 (last run Aug 20, 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, Ntfy is recommended most often — appearing in 71.4% of recommendations, followed by FCM (50%) and APNs (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 push notification tools 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.
Start with the question you are actually asking, because the measured leaders change with it. Ntfy leads the best-in-category prompts at 83.3% of 18 runs and the recommendation prompts at 77.8% of 18 runs. In the alternatives prompts, 9 runs, Gotify, Ntfy and UnifiedPush all sit at 88.9%. The comparison prompts, 9 runs, put APNs and FCM at 88.9% each, with Ntfy at 66.7%. For the self-hosting setup question, 9 runs, Ntfy leads at 66.7% and APNs and FCM follow at 44.4%.
Engine coverage is worth checking too. Ntfy was recommended in 100% of Perplexity's 14 answers and 64.3% of ChatGPT's 14. FCM ranges from 100% of Gemini's 14 answers to 35.7% of ChatGPT's 14.

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.

Ntfy ranks first with a recommendation share of 77.8% of the 63 sampled answers in the 4-week window to 2026-09-05, and it was recommended in every one of the 9 runs on the privacy-first web application prompt. Across all mentions it was recommended in 35 runs and listed in 14, with 1 warning against. Perplexity recommended it in 100% of its 14 answers; Claude and ChatGPT both sat at 64.3% of 14. Pricing is Supporter: $6 a month, $5 a year, last verified 2026-09-05.
FCM ranks second at 54% of 63 sampled answers, and it was recommended in all 9 runs on the open-source alternatives prompt. It was recommended in 22 runs and listed in 12, with 3 warnings against. Gemini recommended it in 100% of its 14 answers, ChatGPT in 35.7% of 14.
UnifiedPush ranks third at 52.4% of 63, recommended in all 9 runs on the same open-source alternatives prompt. Recommended in 18 runs, listed in 15. Grok recommended it in 85.7% of its 7 answers, Perplexity in 35.7% of 14.
APNs ranks fourth at 50.8% of 63, recommended in all 9 runs on the prompt about a mobile app that cannot use commercial cloud messaging. Recommended in 20 runs, listed in 12, warned against in 2. Grok recommended it in 85.7% of its 7 answers, ChatGPT and Perplexity in 35.7% of 14 each. Narrow ground, so buyers outside that constraint should read the intent leaders first.
Gotify ranks fifth at 49.2% of 63, recommended in all 9 runs on the open-source alternatives prompt. Recommended in 16 runs, listed in 15, none warned against. Grok recommended it in 100% of its 7 answers, Claude in 35.7% of 14.
Three of five engines converged. Among the top five, Claude recommended Ntfy most across its 14 answers, ChatGPT recommended Ntfy most across its 14, and Perplexity recommended Ntfy most across its 14. Gemini's most-recommended among the top five was FCM across its 14 answers. Grok's was Gotify across its 7 answers.
The widest gap belongs to FCM. ChatGPT recommended it in 35.7% of its 14 answers; Gemini recommended it in 100% of its 14. That is a spread of 64.3 points, the largest in the category. Ntfy's own range is narrower, from 64.3% of Claude's 14 answers to 100% of Perplexity's 14. A buyer relying on a single assistant would see a different top pick depending which one they asked.
This is the first measured window on record for the category. It runs 2026-08-08 to 2026-09-05, 28 days, with 63 sampled answers and 57 ranked products. There is no prior window to compare against, so no entries, exits or share changes are reported here.
Leading it now: Ntfy at 77.8% of those 63 answers, FCM at 54%, UnifiedPush at 52.4%, APNs at 50.8% and Gotify at 49.2%. Ntfy was also the first product recommended in 16 runs, a first-recommendation rate of 32.7%, the highest among the top five. FCM's first-recommendation rate is 11.8% across 4 runs, despite its second-place overall share.
