Sentry is a Issue trackers platform first released in 2010, originally written in Python and published under a BSD license by Functional Software Inc.. When we detect it, we are seeing a client SDK that a developer added deliberately, wired to a project, an environment and usually to somebody's alerting. Nobody instruments a brochure page with error tracking. The presence of the SDK implies an application with real user sessions, a release process, and a person whose job includes reading a stack trace on a Monday morning. For anyone selling into engineering organisations, that inference qualifies a company more sharply than headcount or traffic estimates do, because it separates businesses that operate software from businesses that merely have a website. As of October 2026 we detect the SDK on 430,354 sites, 312,040 of them in United States, with .com carrying the largest block of suffixes. The country concentration is partly genuine and partly an artefact of where software companies register their public domains, which is a caution that applies to almost any developer facing technology and to this one in particular. Version data is where the list becomes operational. We hold 460 distinct SDK versions, and the string we record most often is 5.4.3. Version spread on a browser SDK is a maturity signal in its own right, because the bundle only changes when someone rebuilds and redeploys the front end. A site running an SDK several major lines behind the current release is telling you that its front end pipeline has been quiet for a long while, which is useful to a vendor pitching a replacement, to a researcher studying dependency drift, and to a security team mapping stale client side code. The limits of detection are worth stating plainly, because they are large here. We can only observe the client side. Backend integrations, which are where a great deal of real usage lives, leave no trace in a page response at all, so the true customer population is meaningfully larger than this count. Self hosted installations that route events through the site's own domain are similarly invisible, and those tend to belong to exactly the security conscious enterprises a researcher would most like to identify. Treat the figure as a floor on adoption and as a reliable sample of client instrumented sites, not as a market share estimate. A per domain lookup answers whether one site is instrumented, which is the wrong direction for most research. The export inverts it: one row per detected site, with the domain, the country, the suffix, the SDK version where one was exposed and the date we last saw it. Working from that file it is possible to segment by version before a security outreach, to size a market before building a competing product, or to measure how quickly a new SDK line propagates across real deployments rather than across download counts. ## Frequently asked questions How many websites use Sentry? webatla detects Sentry on 430K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.
