How this service works
Does a website use Sentry? Fetches the page (homepage for a bare domain) and matches Sentry's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (monitoring). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.
Output
Returns a yes/no answer indicating whether Sentry is detected on the website, along with the evidence snippet (e.g. matching HTML fragment or response header value) that triggered the match, and the technology category ('monitoring').
Example use cases
Sales prospecting tech qualification
“I'm reaching out to leads in my CRM — can you check if stripe.com uses Sentry so I know whether to pitch our monitoring alternative?”
Competitor tech stack research
“I'm doing competitive analysis on our top three rivals — does notion.so use Sentry for error tracking?”
Migration planning pre-assessment
“We're helping a client migrate off Sentry — can you confirm whether their site, example.io, actually has Sentry installed before we start the project?”
Technical details
Endpoint
GEThttps://site.intel.rallylive.ca/site/uses/sentry?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for Sentry specifically. Prefer this over generic technology-stack scanners when you only need a yes/no answer for Sentry with supporting evidence. For bulk checks across many domains, use the corresponding bulk sibling endpoint instead.
Side effects
- Domain is unreachable or returns non-200 status — result may be indeterminate or an error
- Website uses CSP or bot-blocking that prevents the fetch — false negative possible
- Sentry loaded dynamically via client-side JS may not be detected in static HTML inspection
- Bare domain redirect chains may cause timeouts or incomplete fetches
