| What it does | Watches your site around the clock and emails you when it stops answering | Settles whether a site is actually down or only down for you | Tells you an IP address's owner, network and approximate location | Turns any URL into a screenshot, a PDF or structured metadata |
| What it costs you | Free tierA genuinely usable free tier with paid plans for volume or team features. | No sign-upWorks the moment the page loads. No account, no email, no trial. | Free tierA genuinely usable free tier with paid plans for volume or team features. | Free tierA genuinely usable free tier with paid plans for volume or team features. |

| Where it stops | Free monitors run on a five-minute interval, so an outage shorter than that can go unrecorded. | One check from one location — it misses regional outages and says nothing about why a site is down. | Anonymous lookups are rate-limited, and city-level geolocation is an estimate that is often wrong. | Twenty-five requests a day on the free tier, with burst and concurrency caps. |
