Frequently Asked Questions

Which tool has the better free plan? +

UptimeRobot's free plan is more generous for raw monitor count — 50 monitors at 5-minute intervals with no credit card required. Better Stack's free plan caps at 10 monitors but includes unlimited phone, SMS, and push alerts plus a status page, which UptimeRobot's free tier limits more heavily.

Does either tool include on-call scheduling? +

Better Stack is built around incident response and includes on-call scheduling as part of its Responder seat ($34/mo). UptimeRobot is focused on monitoring and alerting rather than on-call rotation management — you'd need to pair it with a separate on-call tool.

Which is better for a simple personal project? +

UptimeRobot — its free tier alone covers 50 monitors, which is more than enough for personal projects, side businesses, or a handful of client sites, with no need to upgrade unless you want faster check intervals.
