Get instant downtime alerts where you already hang out
Everything you need to sleep well
Websites, APIs, servers, ports, DNS records, certificates and cron jobs — checked every minute from our probe, with alerts you can trust.
HTTP(S)
Checked every 60 seconds, not 5 minutes. Custom headers, status codes, payload assertions, and millisecond latency graphs.
SSL certificate
SSL tracking without paying for 'Pro'. Expiry, issuer, and hostname checks with automated alerts 30, 14, 7, and 1 day ahead.
Port (TCP), Ping & DNS
Is your database, mail or custom TCP service accepting connections? We also tell you when your DNS records (A, MX, TXT…) disappear or change.
Heartbeat (cron)
Your cron jobs and backups ping us. Silence means trouble — get notified immediately when background tasks fail silently.
Public status pages
90-day uptime history, incidents and planned maintenance on a fast page you can share.
Developer-first REST API
Everything the panel can do, documented with OpenAPI and code samples.
Everything competitors lock behind 'Pro', free on Pingolab.
Compare what other services charge $29-$49/month for with what Pingolab gives you out of the box.

How it works
Protect your websites and infrastructure in just 3 steps.
Add a monitor
Paste a URL or host. It takes about 20 seconds.
We check it around the clock
Every minute if you like, with response times and SSL tracking.
You hear about outages first
A confirmed outage triggers alerts in seconds — and a recovery message when it's over.
Why is it free?
Because infrastructure monitoring shouldn't be an expensive luxury. Legacy tools charge hefty monthly fees for 60-second checks or SSL tracking. Pingolab has no paid plans, no ads, and no investors — and will never lock features behind a paywall.
Servers cost money, though. Pingolab runs on donations from people who find it useful. If that's you, a coffee goes a long way.

Questions
Everything you need to know about the service.
Is it really free? What's the catch?
There is no catch or tier trap. We don't nag you to 'Upgrade to Pro' after adding a few monitors. Up to 50 monitors with 60-second intervals are completely free, funded transparently by community donations.
How often do you check?
As often as every 60 seconds. You choose the interval per monitor.
How do you avoid false alarms?
A failed check is confirmed with extra checks a few seconds apart, and we test our own connectivity before telling you anything.
Where are the checks made from?
From our server in Europe today. More locations are planned.
What about my data?
We store only what's needed to monitor and alert you. No ads, no selling data, no analytics in the panel or on status pages (only Google Analytics and the Google Ads measurement tag on this website); export or delete your account any time.
Is there an API?
Yes — a complete REST API with keys, rate limits and OpenAPI docs. Our future mobile app will use it too.
Detect outages before your users even notice
No credit card required. 60-second checks, SSL monitoring, and Telegram alerts that competitors charge $29/mo for are free from day one.
