UptimeRobot Alternatives & Comparisons.

Use the same targets, check interval, locations, and timeout/retry settings in both tools, and test for at least a few days to include normal traffic patterns. Validate alert delivery by forcing a controlled failure (like temporarily blocking a known path) and confirm the alert contains enough context to troubleshoot quickly.

Uptime numbers diverge when tools use different check locations, retry logic, timeouts, or what counts as “down” (DNS failure vs. HTTP 5xx vs. slow response). If you see a gap, align those settings first and inspect the raw incident timeline rather than the percentage.

Uptime monitoring checks your services and alerts your team when something breaks. A status page communicates incidents and uptime history to your customers; some tools bundle both, while others price them separately or treat status pages as an add-on.

Hosted monitoring is usually faster to roll out and easier to maintain because you don’t manage the server, upgrades, and networking. Self-hosting can make sense if you need full control, custom checks, or strict data boundaries, but you’ll be responsible for the availability and maintenance of the monitoring stack.

Inventory your monitors (targets, ports, expected status codes, auth, tags) and alert routes first, then recreate them in the new tool and run both in parallel until alerts and incident logs match expectations. Once you’re confident, migrate notifications (escalations/on-call), then disable the old checks so you don’t miss an outage during the cutover.
