HTTP Status Checker

The check shows how a server answers a page request: the status code, response time, content type, and server name. If there is a redirect, the tool shows every step of the chain, not just the final address.

The chain unfolds up to ten redirects; after that the check stops. When a site does not respond or blocks automated requests, the tool shows the reason instead of a status code.

In the User-Agent field you choose who to present yourself as: a browser on a desktop or a phone, the Yandex or Google search robot, or their image robot. This shows whether a site serves the robot the same content as a visitor, or blocks bots altogether.

The default is your own browser's agent, so the site receives exactly the same request as in a regular visit.

One run checks up to 500 pages, one address per line. The tool queries the same domain no more than once per second, so a list of different sites finishes fast, while 500 pages from one site take about eight minutes.

A long check runs in the background: you can close the page and come back to it later at the same address. Finished results export to CSV.
