1 Free & Open-Source UptimeRobot Alternatives
UptimeRobot's free plan limits how many things you can monitor and how often. Uptime Kuma is the open-source alternative that's become the default self-hosted choice for this — unlimited monitors, checked as often as your server can handle.

Frequently asked questions
Is Uptime Kuma as reliable as UptimeRobot for alerting?
Functionally yes — the difference is UptimeRobot checks from its own distributed network, while Uptime Kuma checks from wherever you host it. For most small business sites that's a fine trade for zero monitor limits.
Can Uptime Kuma monitor from multiple regions like a commercial service?
Not natively in a single instance — if you need multi-region checking, you'd run Uptime Kuma on servers in each region. UptimeRobot's paid tiers handle this natively.
Does Uptime Kuma have public status pages like Statuspage?
Yes — it includes a built-in public status page feature, which is often the second thing teams reach for right after uptime checks themselves.
