See every broken link where it sits

Yes. It is free, there is no account, and there is no usage limit. It installs from the Chrome Web Store in one click and updates itself from there.

Chrome 116 or later. Version 2.0 is the current release, and Chrome keeps it up to date from the Chrome Web Store.

No. It checks the links on the one page you are looking at, up to 2,000 of them, when you start a check. Links the page adds later, such as lazy-loaded sections, are checked while the panel is open. Crawling a whole site is what Site Audit in the GrowthHasten product is for.

Yes, and this is the main reason to use an extension rather than a crawler. The scan reads the page you already have open, so anything you can open, it can read. Link checks are sent without your cookies by default, so if the links themselves only work when you are signed in, add that domain under “Check with your cookies” in Settings and they are checked as you see them, rather than showing as unable to verify.

Twelve things worth fixing, ranked. High: broken links, redirect loops, and links to local or staging hosts. Medium: redirect chains, http links on an https page, internal nofollow, links with no anchor text, image links without alt text, and #section links to an id that does not exist. Low: single redirects, generic anchor text such as “click here”, and empty links. Judgment calls are worded as Review rather than as errors, and each issue comes with a suggested fix.

The site blocked the check rather than the link being broken: a sign-in wall (401), a refusal (403), rate limiting (429), LinkedIn’s 999, or a bot-check page such as a Cloudflare challenge. It also covers a site that stopped answering after five failed checks. These links are usually fine, so open them yourself if they matter.

Only if you turn on Exact redirect codes in Settings. Without it, Chrome only tells an extension where a redirect ends up. With it, Hasten LinkLens shows 301 versus 302, every step of a chain, redirect loops, and the real reason a request failed, such as a domain that does not exist. It watches only its own check requests, records nothing about your browsing, and never blocks or changes a request. Leave the setting off and it is never asked for.

Yes. Export saves a CSV of all links, only the links with issues, or the filtered view, and it opens cleanly in Excel. For a single link, Copy diagnostic puts its status, redirect steps, location, issue and fix into a block you can paste straight into a developer ticket.

The link checks go straight from your browser to each destination, so the pages and URLs you check are never sent to us. They carry no referrer, and no cookies unless you add a domain under “Check with your cookies”. Results stay in memory for that tab, and nothing is saved unless you turn on Scan history, which stays on your device.

Only if you ask it to. Scan history is off by default. Turn it on in Settings and Hasten LinkLens remembers, for each page, when it was checked, how many links it had and which were broken, so the next check can tell you what changed, for example “2 new broken links, 1 fixed”. It is kept on your device, up to 300 pages, and Clear history deletes it.

Chrome’s own pages, the Chrome Web Store, local files and anything else that is not an http or https page. Links inside iframes are not scanned either. On a page it cannot check, the toolbar icon shows an exclamation mark and its tooltip says why.
