Bulk URL checker for lists of 100,000 links.

A bulk checker takes a whole list of URLs at once instead of one at a time. Paste or upload up to 100,000 links and it reports the HTTP status code, the full redirect chain and the final URL for every one of them. People also call it a bulk link checker, a bulk URL tester or a bulk URL validator, and it is the same job. What varies between tools is what happens when a site refuses the request, which is where most of them quietly hand you working links labelled as broken.

Yes, and that is what it is built for. One run takes up to 100,000 URLs with no splitting, from a paste, a CSV or Excel file, a domain we read the page list from, or the API. It runs on our machines, so you can close the tab, and we email you when the report is ready.

They will, and that is the whole reason to use us rather than a script. When a site turns us away, that URL is checked again by an independent route before any verdict is written, and requests to one site are paced so a large list does not get the door shut on it. Over the 90 days to 21 September 2026, across 603 jobs and 41,308 domains, 56,892 URLs refused at least one request and 13,597 of them answered on a later attempt. Only what is still refusing after that is reported as refused, and it is never counted as a broken link.

Because we never put them in the same number. A report separates Gone (404 and 410, the only verdict we call broken), Recovered (refused us, then answered by another route), Still refusing, Blocked for legal reasons (451), and Working, with redirect chains and their final URL listed apart. Pages that answer 200 while saying "not found" are detected as soft 404s. When we cannot get a straight answer we say so and name the reason rather than giving you a confidence score to interpret.

Yes, on every plan and during the trial. Turn any list into a scheduled check, pick daily, every three days, weekly or monthly, and we compare each run with the last one and write to you only about the difference. Alerts go to email, Slack or your own webhook, and everyone you add confirms their address first. Setting one up costs nothing; only the runs use credits. Daily is the fastest cadence on purpose, so we never behave like something the sites you are checking should be defending against.

Your first month is on us: 15,000 URL checks on the Starter plan, no credit card. Connect the API, an SDK, the MCP server, a webhook or a scheduled check and the trial grows to a month of Pro: 50,000 URL checks, once per account. After that, one credit checks one URL, whether it came from the site, the API, an SDK, the MCP server or a scheduled run. Plans run from $9 a month up to $99, or buy credits outright with no subscription, and pack credits roll over rather than resetting, and unused credits can be refunded within seven days of purchase if you ask. No card is needed to start.
