How this service works
Does a website use OptinMonster? Fetches the page (homepage for a bare domain) and matches OptinMonster's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (popups). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no boolean indicating whether OptinMonster was detected on the site, along with the evidence snippet from the HTML or response headers that triggered the match, and the technology category (popups).
Example use cases
Competitor martech stack research
“I want to know if my competitor acme.com is using OptinMonster for their lead capture — can you check?”
Sales prospecting for OptinMonster alternatives
“I'm selling a popup tool and want to reach out to sites already using OptinMonster — can you check whether example-brand.com has OptinMonster installed?”
Migration planning away from OptinMonster
“We're planning to migrate away from OptinMonster — can you confirm that our current site mybusiness.com actually has OptinMonster running before we start the transition?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/optinmonster?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, single-domain technographic check specifically for OptinMonster. Ideal for sales prospecting, competitor research, or pre-migration audits where you need to confirm OptinMonster usage quickly and cheaply ($0.01/call) without running a full technology audit suite.
Side effects
- Domain is unreachable or returns a non-200 response — detection cannot be performed
- Site uses heavy JavaScript rendering that prevents server-side HTML fingerprinting — may return false negative
- Incorrect domain format passed — returns error or no result
- OptinMonster loaded asynchronously post-page-load — may not be detected in static HTML fetch
