Broken Link Scan
The free broken link checker for your entire website
Every broken link on your site costs you SEO and trust — and they accumulate on their own, because the pages you linked to don't ask permission before disappearing. Broken Link Scan crawls your whole site (up to 500 pages free, no signup) and verifies every link, image, redirect and SSL cert with real HTTP requests. Clean health-score report in seconds. Paid plans add scheduled re-scans and email alerts when something newly breaks.
Pricing : Freemium (free tier permanent, paid from $6/mo)
Platforms : Web
Features
- Full-site crawl, not just one page — Breadth-first crawl of your entire website, up to 500 pages on the free tier, 5,000 on Pro, unlimited on Agency.
- No signup to try it — Paste a URL and get results in seconds. No account, no credit card, nothing to install.
- Checks more than links — Verifies internal and external links, images (including srcset and picture sources), media files, full redirect chains and SSL certificates in the same pass.
- Real HTTP requests — Results reflect your site right now, not a cached index from last month.
- Health-score report — A readable dashboard with internal vs external breakdown, grouped by source page, clean enough to hand to a client.
- Scheduled monitoring and alerts — Daily automated re-scans with an email the moment a link newly breaks (paid plans).
- Export and history — CSV/JSON export and 90 days of scan history to track what improved (paid plans).
- REST API, webhooks and Slack — Wire scans into your own workflow or get notified in your team channel (Agency plan).
Use Cases
- After a site migration or redesign — Catch the internal links, images and redirect chains that broke when your URLs changed, before Google recrawls the site.
- Auditing a client site — Run a scan, hand over the health-score report. Internal vs external breakdown, grouped by source page, readable by a non-technical client.
- Old blogs with years of archives — External links rot on their own: roughly 5% of the pages you linked to die every year. Find them without re-reading 300 posts.
- Ecommerce catalogs that change constantly — Discontinued products leave dead internal links and missing images behind. Daily scans catch them the day they break.
- Ongoing monitoring instead of one-off checks — Scheduled re-scans plus an email alert the moment a working link starts failing, so you find out before a visitor does.
- WordPress sites, without leaving wp-admin — The companion plugin runs the same checks inside your dashboard, for people who will never open a crawler.
- Pre-launch and pre-campaign checks — Verify every link and asset on a landing page before you drive paid traffic to it.

Hi everyone ! I'm Pierre, a solo bootstrapped dev from France. I built this because I needed to check my blogs for dead links and every option annoyed me: Screaming Frog is a desktop app you install and babysit, Ahrefs and Semrush are $99+/mo suites where link checking is one feature out of fifty, and the free online checkers only look at a single page. So I made the one I wanted. Paste a URL, it crawls your whole site (breadth-first, up to 500 pages free, no signup) and checks every link, image — including srcset and picture sources — redirect chain and SSL cert with real HTTP requests. You get a health-score report in seconds, readable enough to hand to a client. The part I got wrong, in case it's useful to anyone building a crawler: I originally counted HTTP 429 (rate-limited) as "broken". A customer on an agency plan scanned a Cloudflare-shielded site, saw 100% broken links, and churned. 429 is now treated as "skipped", with a per-host circuit breaker. Bot challenges caused the same class of false positive and now trigger an explicit quality warning on the report. Free tier is permanent, no card. Paid starts at $6/mo for scheduled scans and alerts. Happy to answer anything — crawler internals, pricing, or the slow unglamorous growth side.
