CheckLinks

Free Broken Link Checker Chrome Extension

CheckLinks checks every link on the current page, highlights broken links in place, flags redirects and errors, and exports the results to CSV.

Install CheckLinks on Chrome

CheckLinks scans the current page and shows link statuses directly in the browser.

Quickly Find Broken Links, Redirects, and Errors

Inline Overlays

Links are outlined and badged with their status right on the page — green for OK, amber for redirects, red for broken, gray for errors.

Draggable Results Panel

A floating panel shows a sorted results list, summary counts, and a progress bar. Drag it anywhere and close it when you're done.

Filter & Scroll-to

Filter results by status category and click any result to scroll directly to the link on the page.

CSV Export

Download the full scan results as a CSV file for reporting or further analysis.

Detailed Error Reporting

Network errors are classified (DNS failure, connection refused, SSL error, timeout, etc.) with clear explanations.

Lightweight & Dependency-Free

Plain JavaScript, no build step, no external dependencies. Uses Manifest V3 with HEAD requests and GET fallback.

Broken Link Checker for Web Editors, QA Testers, and Developers

CheckLinks is built for quick, single-page link audits. It helps content editors, website owners, developers, SEO reviewers, and QA teams find broken links, redirects, timeouts, and server errors without running a full-site crawl.
