SEO Tool

Broken Link Checker

Enter any URL. We'll fetch the page, extract every outbound link, and check each one in parallel — so you can see 404s, timeouts, redirects, and soft errors in one pass.

Single-page mode: up to 150 outbound links, 8s per link, 20 in parallel, HEAD-first with GET fallback. Whole-site mode: same per-page check, fanned out across same-host pages via Cloudflare Queues. Polls live; results stream in as pages complete.

About this tool

Two modes: single page checks every outbound link on the URL you give it. Whole site follows internal links from that page and checks every outbound link it finds along the way — handy for catching rotted links across an older site in one pass.

Single-page results come back in seconds. A whole-site crawl can take a few minutes; results stream in as it goes. We respect robots.txt and don't store your results.
