About HeaderLens

HeaderLens answers one question quickly – is this website working? – and then shows the evidence: DNS, TLS, HTTP status, redirects, and what the response headers mean.

It is built for two audiences at once. People get a fast, accessible page. Scripts and AI agents get the identical facts as JSON, described by OpenAPI, with timestamps and provenance, so nothing has to be scraped.
