About this tool
Check Site Status is a static, client-side tool with no backend. Paste the headers, curl -i output or HAR you captured and Check Site Status maps the hops and status codes locally.
Because browsers block cross-origin live requests, Check Site Status works from captured headers rather than fetching the URL itself. It behaves the same on desktop and mobile, with nothing stored remotely.
