UptimeRobot checks your website, server or scheduled job and emails you when something stops responding. It's for founders who want a simple monitor with plenty of room on the free plan. Free is €0 with no card: 50 monitors, each checked every 5 minutes. Paid plans start with Solo, from €12 a month billed yearly or €13 billed monthly.
We use UptimeRobot's free plan to keep an eye on our own sites.
What it can do for you
Point it at any URL, host or port, or have it look for a keyword on a page, so you hear about it if a page loads but shows an error. For cron jobs and other scheduled tasks there are heartbeat checks: your job pings UptimeRobot each time it runs, and you're alerted if it goes quiet. Mobile apps aren't named, but you can watch an app's backend with a heartbeat.
Alerts come by email, plus 5 integrations: Google Chat, Discord, Pushover, Pushbullet and Splunk. You get one basic status page, response times are logged, and history is kept for 3 months.
Why it stands out
Fifty free monitors is as many as any hosted free plan we compared on 26 Oct 2026, and its terms say it's "available for any use, including commercial and business use".
The honest downsides
- No SSL or domain expiry alerts on Free. You won't be warned before a certificate or domain lapses.
- Mixed messages on business use. The pricing page calls Free "good for hobby and non-profit projects", while the terms allow commercial use. We've gone by the terms, but check if it matters to you.
- 5-minute checks. A short outage can be over before you hear about it.
- API monitoring is paid only, and there are no slow-response alerts on Free.
Skip it if
- you want certificate and domain expiry warnings without paying
- you need checks more often than every 5 minutes
Alternatives
- Better pick for SSL and domain expiry alerts: HetrixTools. It's free for 15 sites at 1-minute checks, with SSL, domain and nameserver alerts. The catch: you must log in every 90 days, and email alerts go to one address.
- Site24x7 also watches 50 websites free, with SSL certificate checks, but lists only HTTP, SSL and ping checks on Free.
