Free Website Uptime Monitor

We check your website every 5 minutes and email you the moment it goes down — and when it's back.

5 monitors free · No credit card · Email alerts included

How it works

1Add the URLs you want watched — your site, your store, your API.
2We check them around the clock (every 5, 15, 30 or 60 minutes) and track response times.
3The moment a site stops responding, returns an error, or the page no longer contains your keyword, you get an email. Another when it recovers.

What counts as "down"?

A check fails if the site doesn't respond within 15 seconds, returns an HTTP error (4xx/5xx), or — if you set one — the page no longer contains your keyword. Two failed checks in a row trigger the alert, so a single blip won't wake you up.

Questions

Is it really free?

Yes — up to 5 monitors on the free plan, checked every 5 minutes or slower, with email alerts. No credit card required.

How will I know my site is down?

By email, within minutes of the second consecutive failed check. You'll also get a recovery email with the total downtime.

Where do the checks run from?

From our own infrastructure in the US. Multi-region checks are on the roadmap.

Can I check for specific content, not just "is it up"?

Yes — add a keyword (e.g. part of your headline or a product name). If the page loads but the keyword is missing, the check fails.
