Find broken links on any page — right in Chrome

100% free. No signup, no server — everything runs in your browser.
What is Broken Link Checker?
Broken Link Checker is a free Chrome extension that finds broken links on the web page you're viewing. Open a page, click the icon, and the built-in dead link finder tests every link — internal and external — reporting 404 and 410 errors, server errors (5xx), timeouts, and unreachable hosts. Unlike web-based site crawlers, this 404 checker works right in your browser: there is no server, no account, and no data ever leaves your computer. Results appear in a side panel where the link validator marks each URL as valid, redirected, blocked, or broken, and can highlight problem links directly on the page. It's built for SEO specialists auditing landing pages, content editors checking articles before publishing, developers verifying releases, and site owners who just want every link on their website to work.
Why this checker
Accurate results, zero setup
Built to answer one question fast: which links on this page are actually broken — without false alarms and without sending your data anywhere.
Full page scan
Checks every link on the page — including inside frames and modern widgets. Finds 404s, server errors, and timeouts.
Highlight on the page
Broken links get outlined right on the page, and “Locate” jumps to each occurrence — no hunting through the HTML.
No false positives
Links protected by bot-checks or rate limits are reported as “blocked”, not “broken” — so every red result is a real problem.
CSV export
Export the full report or copy just the broken URLs — ready for a ticket, a spreadsheet, or a client email.
Private by design
No server, no account, no tracking. Checks run in your browser and results never leave your computer.
Speaks your language
Available in 52 languages, including full right-to-left support. Free for everyone, everywhere.

FAQ
Frequently asked questions
Is it really free?
Broken Link Checker is completely free — no trial, no limits, no account. Install it and start scanning.
Does my browsing data leave my computer?
Nothing leaves your computer. Broken Link Checker has no server: link checks run directly in your browser, and results are never uploaded anywhere.
What counts as a broken link?
Broken Link Checker reports a link as broken when the page returns 404/410, a server error (5xx), a network failure, or a timeout. Redirects are listed separately so you can review them without treating them as errors.
Why do some links show as “blocked” instead of broken?
Some sites protect themselves with bot-checks or rate limits and refuse automated requests. Broken Link Checker labels those links “blocked” instead of falsely reporting them broken, because they usually work fine for real visitors.
Does it scan my whole website?
Broken Link Checker scans the page you're currently viewing — that keeps it fast, accurate, and private. Open the pages you care about and scan each in one click.
What permissions does the extension need?
Two. Access to websites is requested on your first scan and used only to read links on the page and check whether they respond. Local storage keeps your settings (timeout, parallel requests, highlighting) in your browser. Nothing else is requested.
Stop losing visitors to dead links
Free forever. Installs in seconds. Works on any page you can open.
