In short
An uptime monitor is a tool that repeatedly checks whether your website or service is reachable and responding correctly, then alerts you the moment it stops. Uptimehub checks your endpoints every minute from 6 global regions and, when a check fails, retries automatically from other regions to confirm the outage before it pings you, usually within seconds. It supports eight check types in one flat plan: HTTP, ping, TCP port, SSL, DNS, keyword, and cron heartbeat. Every check runs read-only from the outside, exactly as a real visitor would experience your site, so there is nothing to install and no agent to run on your servers. When something recovers, you get a clear all-clear too.

Uptime monitoring for developers, SaaS teams and agencies
Checks every minute
Uptimehub probes your endpoints on a tight interval so a real outage is caught in the same minute it starts, not fifteen minutes later.
Multi-region by default
Every monitor runs from 6 regions with automatic cross-region retry, so a single flaky path never turns into a false alarm.
All check types, one plan
HTTP, ping, TCP, SSL, DNS, keyword, and cron heartbeat checks are all included, so you monitor everything without upgrading tiers.
Priced per monitor, never per seat
Add your whole team at no extra cost and pay only for the monitors you run, so growing headcount never inflates your bill.

FAQ
Questions buyers ask about Uptime monitoring
An uptime monitor sends a request to your URL or host on a fixed interval from outside your network and records whether it got the expected response. If a check fails, a good monitor retries from other locations to rule out a network fault on its side, then raises an alert only once the failure is confirmed from more than one place.
Once a minute is the practical standard for anything that generates revenue, because it caps how long an outage can run before you know about it. Five minute intervals are acceptable for low-stakes sites, but they cannot support a 99.99 percent availability target, since the entire monthly downtime budget is shorter than one check gap.
No. Uptimehub sends the same kind of request a visitor would, once a minute, which is a negligible fraction of normal traffic for any real site. Checks run read-only from outside your infrastructure, so there is no agent consuming CPU or memory on your servers and nothing installed that could affect performance.
Uptime monitoring checks your service from the outside and answers whether customers can reach it. Server monitoring runs an agent on the machine and reports internal metrics such as CPU, memory, and disk. They answer different questions: a server can look perfectly healthy on its own metrics while a DNS or certificate fault makes it unreachable.
Usually because the outage was brief, regional, or intermittent, and had cleared by the time you checked. That is why cross-region confirmation matters: a failure seen from one location and confirmed from another is a real problem your visitors in that region experienced, even if the site loads normally from your desk.
