/tools/classify-ua?ua=Lightpanda%2F1.0Every 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.
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.
Not observed. It carries no URL and no contact address in its user-agent, so there is nowhere documented to ask what it is.

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,
2026-09-04 09:50:07Z to 2026-09-04 09:50:07Z 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
.
