UptimeRobot is a popular choice for basic uptime checks. Sandglass focuses on modern teams that need integrated status pages, better reporting, and collaborative incident workflows.
Both tools monitor uptime, but they differ in how they handle communication, reporting, and team workflows.
Sandglass is designed for teams that want monitoring, alerting, and hosted status pages in one place rather than stitching together multiple tools.
For very simple needs—like monitoring a handful of sites without extra reporting or communication requirements—UptimeRobot's basic offering may be sufficient.
If you primarily need basic uptime checks, either tool can work. If you also need hosted status pages, clearer incident communication, and reporting for clients or stakeholders, Sandglass may be a better fit.
