Catch SEO disasters before Google does: watches robots.txt, XML sitemaps and key pages for Disallow: /, noindex, canonical and status changes, sitemap URL drops and errors. Diffs vs last run, Slack/webhook alerts, HTML report.

Check hundreds of URLs at once: HTTP status, the full redirect chain (301/302, http to https, www), security headers and SSL certificate expiry. One health verdict and issue list per URL. No login, no proxy.

Broken Link Checker & Bulk URL Status Code Checker

kilndata/broken-link-checker

Check the HTTP status of thousands of URLs, or crawl a site and test every link on it. Status code, full redirect chain, final URL, response time, error type (DNS, SSL, timeout, 4xx, 5xx) and the page each broken link sits on. HEAD with GET fallback, polite per-domain limits.

Free beta: compare permitted public product pages with supplied SKU, price, currency and availability. Static JSON-LD only; ambiguous evidence stays inconclusive.

Crawl your own website and find every broken link: 404 and other 4xx errors, 5xx server errors, timeouts, redirect chains and loops, plus dead external links, with the page each one was found on and its anchor text. Respects robots.txt and Crawl-delay. CSV report included.

Redirect Checker & Bulk URL Status: Chains, Loops, 301 Map QA

cygnix_labs/redirect-checker

Bulk redirect checker and HTTP status code checker. Traces every hop (301/302/307/308, meta refresh) and flags redirect chains, loops, 404s, soft 404s, noindex targets and redirect-map mismatches after a site migration. First 20 URLs free, then $0.0008/URL.

Crawl a site from a start URL or sitemap, obeying robots.txt and at most two requests a second. Check each link and asset once; report broken and redirected links with status, redirect chain, anchor text and source pages, plus a summary.
