Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access.

About Sentry

An error tracker is one of the few things on a page that describes the team behind a site rather than the site itself. 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 September 2026 we detect the SDK on 386,371 sites, 274,381 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 443 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 386K websites, refreshed daily, each with its domain, DNS, WHOIS, IP, country and ranking.

Can I download the list of websites using Sentry?

Yes, as structured JSONL. Grab a free sample first.

What's included for each site, and how fresh is it?

Domain, DNS, RDAP/WHOIS, the full technology stack, IP & country, PageRank and Harmonic, re-detected and re-exported daily.

How do I find the websites using Sentry?

Buy the technology dataset, then download the complete list of domains we detect using Sentry, re-exported every day.

What else is in the Sentry technology data?

Each row places Sentry next to the other technology on the same site, plus DNS, WHOIS, IP, country and ranking.

Can I download just the sites using Sentry, or the whole database?

Both. Every site running Sentry comes in the Technologies dataset, one downloadable file. Or buy All data for the entire database: technologies plus identity, ranking, DNS and RDAP/WHOIS for every domain, combined in one file. Daily fresh export.

How do I download the list of websites using Sentry?

Three steps: (1) grab the free 10,000-row sample to inspect the schema, (2) buy the Technologies dataset, (3) download the full list of every domain we detect running Sentry as a JSON Lines file. It is re-exported daily, so you can re-download the freshest list any time inside your access window. Each row carries the domain plus DNS, WHOIS, IP, hosting country and rank.
