Bulk HTTP Status Code Checker

Yes. Checking URLs is free with no signup and no credit card: up to 100 URLs per check and 400 URLs a day (1,000 a day with a free account). A free account also keeps one saved list of up to 100 URLs. Paid plans, from $9 a month, re-check saved lists for you every day or every hour and email you when something changes.

You can check up to 100 URLs simultaneously with the free tool. Paste them into the box one per line or upload a .txt or .csv file, then export the results as CSV.

HTTP Tiger checks up to 100 URLs at once and reports the status code (404, 301, 500, 503 and so on) and response time for each, with a DNS propagation check across Google, Cloudflare, OpenDNS and Quad9, all free with no signup. It is built for SEO migrations, link audits and debugging.

Not exactly. UptimeRobot watches a few endpoints every few minutes. HTTP Tiger checks whole lists of URLs: free on demand, or automatically every day (Pro, $9 a month) or every hour (Agency, $29 a month) with an email when a status code or redirect changes. For minute-by-minute uptime monitoring, use our sister product Status Tiger.

You can check any website or API endpoint on demand for free, and a free account saves one list you can re-check with one click. Automatic re-checks with email alerts are on the Pro plan (daily, $9 a month) and the Agency plan (hourly, $29 a month).

After checking your URLs, click the 'Check DNS' button on any result to see how four public resolvers (Google DNS, Cloudflare, OpenDNS and Quad9) answer for that domain. If they all return the new address, the change has reached the major resolvers.

Use the free HTTP Header Checker to view a site's response headers, security headers, server software, caching rules, and redirect behavior for any URL. It helps diagnose misconfigurations and missing security headers.

Use the Is It Down checker, which tests the site from external servers. If it reports UP but you cannot load the page, the problem is local — your DNS, ISP, VPN, or firewall; if it reports DOWN, the site is likely down for everyone.

A 404 error means 'Not Found' — the server cannot find the requested page, usually because it was deleted, moved, or the URL was mistyped. You can look up any status code in our HTTP status codes reference.

Yes. Checks run server-side over HTTPS, no account is required, and we do not sell your data. You can paste and test URLs without creating a login.
