Broken-link & site auditing

Catch broken links before your visitors do.

LinkCanary audits every page, link, and endpoint across your site and chirps the second it finds something broken. A dead link never costs you another customer.

The internet rots quietly

Links die. Servers hiccup. Nobody tells you.

Every site decays. A vendor moves a page, a deploy 500s, a cert expires at 2am. Your visitors hit the wall long before you ever notice, and most of them simply leave.

Dead links bleed trust & SEO. Google demotes pages full of 404s, and shoppers don't come back after a broken checkout.
Broken links pile up silently. A dead link can sit unnoticed for weeks before a customer or Google finds it first.
Manual checks don't scale. You can't click every link on every page, every day, forever.

Everything in one perch

Keep every link alive across your whole site

One lightweight canary audits your whole web presence, from the homepage to the deepest outbound link.

On-demand & scheduled audits

Run a full audit whenever you want, or on a daily or weekly schedule, scanning your entire site in minutes.

Broken-link crawling

Crawls your entire site on a schedule and flags every 404, dead redirect, and rotten outbound link, internal and external.

Instant alerts

Email, Slack, Discord, SMS, PagerDuty, or webhook. Know within seconds, with the exact URL, status code, and screenshot.

Shareable reports

Clean, shareable audit reports with a public link for every crawl, so clients and teammates see exactly what was found.

SSL & domain expiry

Get warned weeks before a TLS certificate or domain registration lapses, so you never get caught by a surprise expiry again.

History & insights

Track issues across audits over time and export shareable CSV and HTML reports. Proof your site is clean, ready to hand off.

Live in three minutes

Drop in a domain, paste a sitemap, or connect a repo. LinkCanary maps every page and link automatically.

2

We audit your site

The canary crawls every page, link, and certificate and checks them for problems, on demand or on a schedule you set.

3

You get chirped

The instant something breaks, you get a precise alert where you already work, before a visitor ever notices.

Watch an audit run, link by link

This is LinkCanary auditing a real site. Healthy responses scroll by quietly. The moment a link is broken, the canary sounds off.

Smart retries confirm a link is really broken before flagging it, so no false alarms.
Full request context: status code, latency, redirect chain, and a screenshot attached to every incident.
Recommended fixes come with every issue, alongside the source page and status code.

Questions, answered

Everything you might ask

How often does LinkCanary check my links?+
Run an audit on demand any time, or schedule recurring audits, daily or weekly on paid plans. You decide when LinkCanary scans your site.
What exactly can it check?+
Websites and landing pages, API endpoints, internal and outbound links, redirects, SSL certificates, domain expiry, keyword presence (e.g. "is the word ‘checkout’ still on the page?"), and specific status codes. If it speaks HTTP, the canary can check it.
How do alerts reach me?+
Email, Slack, Discord, SMS, PagerDuty, Microsoft Teams, or any webhook. Every alert includes the failing URL, status code, response time, and a screenshot. We auto-notify you again the moment it recovers.
Is there really a free plan?+
Yes. 50 checks free, forever, no credit card required. It's perfect for personal sites and side-projects, and you can upgrade when you need bigger audits or more alert channels.
Can I audit staging or password-protected sites?+
Absolutely. Add custom request headers, basic-auth credentials, or bearer tokens per audit, and LinkCanary will check authenticated and internal environments just like production.
How is this different from Google Search Console?+
Search Console reports problems days later, only for pages Google has crawled. LinkCanary checks your links on your schedule and alerts you in seconds, covering APIs, SSL, redirects, and outbound links that Search Console never touches.

Never lose a visitor to a dead link again.

Run your first audit in two minutes. Let the canary keep your links clean.
