Uptime & broken-link monitoring

Catch broken links
and downtime before
your visitors do.

LinkCanary watches every page, link, and endpoint around the clock — and chirps the second something breaks. A dead link or silent outage 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.

01
Dead links bleed trust & SEO.

Google demotes pages full of 404s, and shoppers don't come back after a broken checkout.

02
Outages hide in plain sight.

The average downtime goes unnoticed for 90+ minutes when no one is watching.

03
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 —
and every page online.

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

01

Uptime monitoring

Checks your sites and endpoints as often as every 30 seconds, from multiple regions — so a blip in one location never fools you.

02

Broken-link crawling

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

03

Instant alerts

Discord, Telegram, ntfy, email — or any webhook you point us at. Seconds, not hours, with the exact URL, status code, and screenshot.

04

Public status pages

Hosted status pages on your own domain — keep customers informed and cut support tickets during incidents.

05

SSL & domain expiry

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

06

History & insights

Response-time graphs, incident timelines, and shareable uptime & SLA reports — proof of reliability, ready to export.

Live in three minutes

Set it, and let the canary sing.

1

Add your URLs

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

2

We watch, 24/7

Our canaries ping your pages, endpoints, links, and certs on your schedule — from data centers worldwide.

3

You get chirped

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

And then it goes quiet again. A good canary is mostly boring.

See it in action

A watchful eye that never blinks.

This is LinkCanary running live checks against a real site. Healthy responses scroll by quietly — the moment a link rots, the canary sounds off.

Multi-region checks

Confirm an outage is real before alerting — no false alarms at 3am.

Full request context

Status code, latency, redirect chain, and a screenshot attached to every incident.

Auto-resolve

Closes the incident and tells you the moment the link is healthy again.

Questions, answered

Everything you might ask.

How often does LinkCanary check my links?+
As often as every 30 seconds on paid plans, and every 5 minutes on the free plan. You can set different intervals per monitor — tight checks for your checkout flow, relaxed ones for your blog archive.
What exactly can it monitor?+
Websites and landing pages, API endpoints, internal and outbound links, redirects, SSL certificates, domain expiry, keyword presence, and specific status codes. If it speaks HTTP, the canary can watch it.
How do alerts reach me?+
Discord, Telegram, ntfy, or plain email — and any webhook, so Slack, Mattermost, Matrix, Gotify, n8n or your own endpoint all work too. Every alert carries the failing URL, status code, response time, region, and a screenshot, and we tell you again the moment it recovers.
I self-host everything. Does that still work?+
Yes — that's who this is built for. Nothing in LinkCanary requires a hosted chat service. ntfy and Gotify are first-class, and a webhook covers whatever else you run, whether that's Mattermost, Rocket.Chat, Matrix, or a script on your own box.
Is there really a free plan?+
Yes — 50 checks free, forever, no credit card required. It's built for personal sites and side-projects, and you can upgrade the moment you need tighter intervals or more channels.
Can I monitor staging or password-protected sites?+
Absolutely. Add custom request headers, basic-auth credentials, or bearer tokens per monitor, 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, and only for pages Google has crawled. LinkCanary checks your links on your schedule and alerts you in seconds — covering uptime, APIs, SSL, and outbound links that Search Console never touches.

Never lose a visitor to a dead link again.
