What this tool shows
Every HTTP request returns a status code, a set of response headers, and a body. This tool sends a real request and lays all of that out: the status and reason, a timing breakdown from DNS through download, the resolved IP, the content type and size, and every response header the server sent. It is the fastest way to confirm what a URL actually returns.
Frequently asked questions
What do the status codes mean?
Codes in the 200 range mean success, 300 range mean a redirect, 400 range mean a client error like not found or unauthorized, and 500 range mean a server error. The exact code narrows down what happened.
What is time to first byte?
Time to first byte, or TTFB, is how long the server took to start responding after the connection was ready. A high TTFB usually points to slow server-side processing rather than a network problem.
Why do the response headers matter?
Headers control caching, security, content type, and more. Checking them confirms things like cache rules, compression, and security headers are set the way you expect.
