HTTP Status Check

About

HTTP Status Check is a Chrome extension for quickly testing a single URL or checking a batch of URLs to see exactly how each request resolves.

It is built for SEOs, developers, QA teams, and anyone who needs a fast way to inspect status codes, redirects, and response behaviour without leaving the browser.

Check one URL or paste in a list of URLs and run them together. The extension uses HEAD first for speed, then automatically retries with GET when a server rejects HEAD requests. You can trace every redirect hop, not just the final destination, making it easier to spot redirect chains, loops, and unexpected behaviour.

Each result includes a clear response summary with the final status code, redirect count, total response time, server header, content type, content length, and HSTS where available. You can then open a detailed inspector to view the full request chain and response details for any individual result.

Results can be filtered by 2xx, 3xx, 4xx, 5xx, or network errors, making large batches easier to review. You can also export the current result set to CSV for reporting, auditing, or further analysis.

HTTP Status Check also includes flexible request controls, including configurable method mode, timeout, redirect limit, and parallel check count. User-agent presets let you test requests using different browser or bot profiles, which is useful when comparing how servers respond across environments.

To make repeat checks easier, the extension remembers your draft input and settings, can prefill the current tab URL, and shows progress while checks are running.
