Scan any webpage for broken and redirected links. One click. Zero configuration.
Open any webpage and click the LinkCheck icon in your browser toolbar. A popup panel appears showing the current page.
LinkCheck finds every link on the page and checks each one in the background. Results stream in as they're discovered — no waiting for the full scan to finish.
Broken links show a red badge, redirects show orange, and working links show green. Use the tabs to filter by status. Hover over highlighted links on the page to see tooltips with details.
Click Export to download a Markdown report of all results. Share it in a pull request, issue, or email.
Broken links appear the instant they're found. No need to wait for the entire scan to complete.
Broken links get a red dashed outline, redirects get orange. Hover to see status codes and redirect targets right on the page.
Uses HEAD requests to minimize bandwidth, falls back to GET when needed. Handles timeouts, redirects, and server errors gracefully.
Download a clean report listing all broken links and redirects. Ready to paste into GitHub issues, PRs, or documentation.
Skip image links, ignore 403 errors, toggle redirect visibility, or turn highlights on and off. Your preferences are saved automatically.
No analytics, no tracking, no data collection. The only network requests are to the links already on your page. Read the full policy.
Toggle these in the popup header. Your choices are saved between sessions.
| Option | What it does |
|---|---|
| Skip images | Excludes links that point to image files (.png, .jpg, .gif, .svg, .webp, etc.) from the scan. |
| Skip 403 | Treats HTTP 403 (Forbidden) as non-broken. Useful for sites that block automated requests. |
| Show redirects | Controls whether redirected links appear in the "All" tab. The Redirects tab is always available. |
| Highlight | Overlays colored outlines on broken and redirected links directly on the page, with hover tooltips. |
LinkCheck works on Chrome, Microsoft Edge, Brave, and any Chromium-based browser (version 88 or later). Firefox and Safari are not currently supported.
LinkCheck sends requests to every link found on the page you're scanning. Without broad host permission, it could only check links on a handful of pre-approved domains — which would make it useless for most pages. The permission is used solely for link checking, never for reading or modifying page content on other sites.
No. The only outbound requests are HTTP checks to the URLs already visible on the page. No analytics, telemetry, or tracking of any kind. See the privacy policy for details.
Some servers block automated requests (returning 403 Forbidden) or behave differently for HEAD requests. Try enabling the "Skip 403" option. Links behind login walls or CAPTCHAs will also appear broken since LinkCheck can't authenticate.
A link is flagged as a redirect when the final URL after following all redirects is different from the original link (ignoring trailing slashes). For example, if http://example.com redirects to https://www.example.com, that's a redirect. Updating these links improves page load speed and SEO.
Yes — if you're already logged in and can see the page, LinkCheck can scan it. It runs directly in your browser using your existing session. However, links that themselves require authentication will likely show as broken.
Just send an email to support@gameshoutout.com — we'd love to hear from you. You can also leave a review on the Chrome Web Store.
