Broken Link Checker
Paste a list of URLs and every link is checked by its real HTTP status. 404s, 500s and redirects flagged in a clear table, with response times and a CSV report. It runs entirely in your browser — no signup, no installation, and nothing you paste or drop leaves your device.
How to Check Links for Broken Ones
This broken link checker finds dead links in any list of URLs — paste your links (one per line, or copy them straight from a sitemap or a page's source) and click Check links. Each URL is fetched through a public proxy and classified by its real HTTP status code: green for pages that load, yellow for redirects, red for links that return an error like 404 or 500. The result table shows the status, the exact code and the response time for every link, with a summary at the top and a copyable CSV report if you want to hand the list to whoever maintains the site. Broken links cost you trust and rankings — visitors click a promising link, hit an error page and leave. Running a quick check before you publish keeps your site healthy, and this tool does it in seconds: no account, no upload of your data, nothing stored. If a link can't be reached because the check service is busy, it is marked as failed rather than broken, so you never get a false alarm.
