Checkly and UptimeRobot were each named in 4 of the 6 buyer questions we put to ChatGPT and Gemini about synthetic monitoring tools, more than any other product in the category. We asked six versions of the same shopping question on 4 August 2026, gave each assistant one live web search, and logged every product named and every source domain behind the answers. No other tool was named in more than 2 of the 6.
A cluster of eight products tied at 2 of 6 answers each, a 33% share apiece: Catchpoint, Datadog, Datadog Synthetic Monitoring, Dotcom-Monitor, Dynatrace, ManageEngine Applications Manager, Site24x7 and SpeedCurve. Two of those rows are one brand under two labels. The assistants wrote Datadog two ways, "Datadog" and "Datadog Synthetic Monitoring", and we kept both rows at their measured counts rather than merging them into a number the data never shows. Sematext is split the same way further down, named once as "Sematext Cloud" and once as "Sematext Synthetics".
How the shortlist changed from question to question
The plain query "best synthetic monitoring tools" returned an all-enterprise list of 8 products: Dynatrace, Datadog, New Relic, Site24x7, ManageEngine Applications Manager, Dotcom-Monitor, Sematext Cloud and Prodzilla. Neither Checkly nor UptimeRobot, the two most-named tools across the whole run, appeared in that answer at all. A vendor who only checked the headline "best" question would conclude the category belonged to the enterprise suites.
Add one word, "free", and the list collapses to 3 products: Checkly, UptimeRobot and Datadog. That "best free synthetic monitoring tools" answer is the shortest of the six, and it is the first place Checkly and UptimeRobot appear. Datadog is the only name that carried over from the enterprise "best" list into the free one.
"Most affordable synthetic monitoring tools" returned a different 6: Site24x7, Sematext Synthetics, UptimeRobot, Grafana's k6, Checkly and Better Stack. Three of those, Better Stack, Grafana's k6 and Sematext Synthetics, appeared in the affordable question and nowhere else in the six. Site24x7 is the single bridge from the enterprise "best" list to the affordable one.
In total, 12 of the 22 product names we recorded were named in only 1 of the 6 questions. "Best" alone surfaced New Relic, Prodzilla and Sematext Cloud. "For small teams" alone surfaced OnlineOrNot, Pingdom and Uptime Kuma. "What should I use" alone surfaced LogicMonitor. "Most affordable" alone surfaced Better Stack, Grafana's k6 and Sematext Synthetics. "Recommendations" alone surfaced Uptrends and Zabbix. Each of those twelve owes its entire visibility to one phrasing of the question.
The pattern is consistent across the six: "best" pulls enterprise suites, while "free" and "affordable" pull a lighter, cheaper set that the plain "best" query never mentions. A product can be a top answer to "affordable" and invisible to "best". That is why checking one phrasing of your category question tells you almost nothing about your real coverage.
Where the answers came from
Three domains fed all 6 answers: catchpoint.com, dotcom-monitor.com and thectoclub.com. Reddit was just behind at 5 of 6, and uptimerobot.com also fed 5 of 6. Those five domains are the retrieval backbone of this category: land on them and you are in contention for almost every question.
Community discussion carried real weight. Reddit was cited in 5 of the 6 answers and Quora in 1, so a human thread sits behind five of six responses. Synthetic monitoring is not a category the assistants answer from vendor marketing alone.
Here is the insight that matters most for a vendor: your own domain being in the retrieved sources is worth as much as market share. UptimeRobot's own site was in the sources for 5 of 6 answers, and UptimeRobot was named in 4 of 6. More striking, catchpoint.com and dotcom-monitor.com each fed all 6 answers, largely as publishers of "best synthetic monitoring" roundups that list their rivals, yet each of those two products was itself named in only 2 of 6. Publishing the comparison page put their domain into every answer whether or not the assistant picked their product.
No review directory appeared in any of the 6 answers. G2 and Capterra, the sites most software vendors pour budget into, fed zero of the six responses. For synthetic monitoring, ChatGPT and Gemini reached for roundup blogs, vendor comparison pages and Reddit instead.
What this means if you sell a synthetic monitoring tool
The takeaway for a vendor is blunt: the source list decides who gets named, not who has the most customers. Every product at the top of our count has its name on the pages the assistants retrieved. thectoclub.com's roundup fed all 6 answers, and the tools that roundup lists are the tools that got named.
So the work is specific. Be on the pages that fed these 6 answers: the roundups (thectoclub.com, debugbear.com, qawerk.com, kentik.com and splunk.com), the two vendor comparison pages that reached every answer (catchpoint.com and dotcom-monitor.com), and the Reddit threads behind 5 of 6. UptimeRobot shows the ceiling of doing this well: its own domain in 5 of 6 source sets, its product in 4 of 6 answers. A tool with more paying customers but none of these pages would score 0 of 6.
None of this shows up in a dashboard of your own signups. The only way to know whether you are in these answers is to ask the six buyer questions the way a buyer phrases them and read the sources back, which is exactly the measurement on this page.
The full list, counted
Every product named in more than one of the 6 answers, counted exactly as ChatGPT and Gemini wrote it. Share is out of the six answers. Datadog appears on two rows because the assistants used two names for it, and we left both as measured.
| Product | Named in | Share |
|---|---|---|
| Checkly | 4 of 6 | 67% |
| UptimeRobot | 4 of 6 | 67% |
| Catchpoint | 2 of 6 | 33% |
| Datadog | 2 of 6 | 33% |
| Datadog Synthetic Monitoring | 2 of 6 | 33% |
| Dotcom-Monitor | 2 of 6 | 33% |
| Dynatrace | 2 of 6 | 33% |
| ManageEngine Applications Manager | 2 of 6 | 33% |
| Site24x7 | 2 of 6 | 33% |
| SpeedCurve | 2 of 6 | 33% |
The remaining 12 product names were each cited in 1 of 6 answers, a 17% share: Better Stack, Grafana's k6, LogicMonitor, New Relic, OnlineOrNot, Pingdom, Prodzilla, Sematext Cloud, Sematext Synthetics, Uptime Kuma, Uptrends and Zabbix.
Why we ran this
We build Glotier, and we do not sell a synthetic monitoring tool, so we are correctly absent from all 6 of these answers. That is the honest result: the assistants named the products that fit the question, and none of them is ours.
This measurement is the entire thing Glotier does, pointed at your category instead of this one. We put the buyer questions to ChatGPT and Gemini, record who gets named, and show you the exact source pages behind each answer so you can see whether your product is on them. If you sell a synthetic monitoring tool, running this on your own name is free, needs no account, and takes about a minute.
