Looking for a UptimeRobot alternative?

In October 2024, UptimeRobot changed its free tier to restrict commercial use. If you were using it to monitor a live product, client site, or anything business-related, you were no longer covered without paying. The entry-level paid plan starts around $7/month.

For a lot of people that was the nudge to start looking elsewhere, particularly for something that does not lock useful features behind tiered plans.

What to look for

The main things worth checking before switching: how often the tool actually checks your site, what alert channels are included by default, and how the pricing scales if you add more monitors. A lot of tools advertise low entry prices but charge more once you need Slack alerts or faster check intervals.

Worth knowing too that Freshping, another popular free option, shut down entirely in early 2026. If you were using both, we wrote about the best places to go from here. If you are newer to uptime monitoring and want a broader overview of what these tools actually do, our guide on how uptime monitoring works is a good starting point.

How SiteSheriff compares

SiteSheriff charges per check at $0.000005 rather than a flat monthly subscription. There are no tiers, no monitor limits, and check intervals go down to 10 seconds on every account. Email, Slack, and webhook alerts are all included as standard.

You get $2 of free credit when you sign up, no card required, so it is easy to try before committing to anything. See a full breakdown of how SiteSheriff differs from the subscription-based alternatives.
