Secure Broken Link Checker & 404 Detector
Audit your entire website for dead links and 404 errors with our browser-native recursive scanner. By combining our high-speed crawler with a secure CORS proxy, we identify every broken internal and external link without your data ever leaving your device. All processing happens locally in your browser.

Eliminate 404 Errors Locally
Broken links are more than just a nuisance; they are "SEO leaks" that drain your crawl budget and frustrate your users. Our Broken Link Checker uses a browser-native recursive engine to crawl your site, extract every link, and verify its health in real-time.
By leveraging Sovereign Compute, we ensure that your internal site structure is never sent to a third-party server. All link discovery and status pings happen directly in your browser memory, providing a secure and private auditing environment.
Recursive Discovery
Our crawler navigates your internal link graph up to 50 pages deep, ensuring no hidden 404 error goes unnoticed in your sub-directories.
Status Verification
We ping every extracted link (internal and external) using secure CORS-compliant proxies to retrieve accurate HTTP status codes.
Detailed Mapping
Every broken link is mapped back to its "Source Page," making it easy for you to locate and fix the dead end in your CMS or code.
