Free uptime monitor

Monitor your website and get an email the moment it goes down — and again when it recovers. Unlimited monitors, checks as often as every minute, completely free with no limits.

What is website uptime monitoring?

Uptime monitoring means checking your website at a regular interval to confirm it's online and responding. Instead of finding out your site is down because a customer emails you — or worse, never tells you and just leaves — a monitor checks it around the clock and alerts you the instant something breaks.

Busalab pings your site from our servers every few minutes. If it stops responding, times out, or returns an error, you get an email straight away. When it's back, you get a second email. That's the whole point: you're the first to know, not the last.

A free UptimeRobot alternative for small sites

If you run a small business site, a portfolio, a shop or a landing page, you don't need an enterprise monitoring suite — you need to know when it's down. Busalab gives you exactly that for free: HTTP and HTTPS checks, a check interval down to one minute, email alerts for both downtime and recovery, and no cap on how many sites you watch.

Why downtime costs more than you think

A site that's down doesn't just lose sales while it's offline. It quietly loses trust: a customer who hits an error once often doesn't come back to try again. And if you find out hours later, the damage is already done. Monitoring turns a silent problem into a message in your inbox you can act on in minutes.
