It describes itself, inside its own user-agent, as QNetworkAccessManager 6.11.2; Arch Linux; en_US; 64 bit. That is the client's own words, quoted; this page makes no claim about what it is for.

Our instrument classed it

agent×64 — that is our classifier's label from the user-agent, not the operator's, and it has been wrong before.

How to verify it is really them

Not observed. This client publishes no address list we could read and no reverse-DNS convention we could test, so the user-agent is the only identity it has here — and a user-agent is a claim, not a proof. Anyone can send this string.

  What is QtCreator/20.0.1 (QNetworkAccessManager 6.11.…? This exact user-agent run through the catalogue: which crawler it is, who operates it, what the crawl is for, what blocking it costs — or an honest "not recognised" if it is nobody we know.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.

What it publishes about you afterwards

Not observed. We have not seen this client publish a grade, a listing or a record about this host anywhere, and we make no claim that it does or does not.

Its own documentation

Not observed. It carries no URL and no contact address in its user-agent, so there is nowhere documented to ask what it is.

Method, and what this page will not say

Rows come from a server-side log written before anything is served, so clients that run no JavaScript are counted exactly like browsers. The window is the whole life of the log, 2026-09-01 06:24:35Z to 2026-09-14 05:54:49Z UTC, and it is stated on every number because a count without a window is not a fact. Addresses are stored as salted hashes and counted, never printed. Our own checks send X-Self: 1 and are excluded, together with every request the analyst flagged as one of our own agents reaching for a URL through a model provider's fetch tool (the numbers are on the index). Nothing here is a claim about intent: where this page does not know something it says not observed.
