## TL;DR
- SiteGuardian wins on the watch, not on the free ceiling. UptimeRobot is the broadest free uptime monitor in the category, with up to fifty monitors on a 5-minute cadence, but it is strictly an HTTP-ping product — no broken-link crawler, no checkout-path probe, no form-path probe, and SSL expiry alerts are paid-only.
- When UptimeRobot: many monitors, free ceiling, a public status page, and 5-minute cadence is enough.
- When SiteGuardian: minutely probes on Pro, one loud email per outage, and a paid product that does not pretend the dashboard is the job.
- The verdict: SiteGuardian for the watch; UptimeRobot for the free ceiling.

## Buying-time FAQ
- Q: Does SiteGuardian have a free tier like UptimeRobot?
  A: No. SiteGuardian is paid from the first URL. Starter is $19 a month, Pro is $39 a month, Lifetime is $299 once. UptimeRobot still runs a free tier (around fifty monitors on a 5-minute cadence as of July 2026). Choose SiteGuardian when you want the smallest tool and one alert; choose UptimeRobot when the free plan is the deciding factor.
- Q: Is the probe cadence the same as UptimeRobot?
  A: On UptimeRobot paid, both probe every minute. On UptimeRobot Free the cadence is five minutes, averaging around two-and-a-half minutes detection latency. SiteGuardian probes every minute on Pro and every five minutes on Starter and Lifetime. No free-tier downgrade in cadence.
- Q: Does SiteGuardian support a public status page like UptimeRobot?
  A: No. SiteGuardian is intentionally the smallest product; status pages are something you would pair alongside it, not a feature we ship. If a public status page is a buying-time requirement, UptimeRobot’s free status page is the better fit.
- Q: Can I keep using UptimeRobot’s free tier while I try SiteGuardian?
  A: Yes. Run both for a fortnight. The second alert is louder than the first. Pick the one that fits the way you want to be notified.
- Q: Which one is cheaper for one storefront?
  A: UptimeRobot Free is cheaper at $0. SiteGuardian Starter at $19/mo is cheaper than UptimeRobot Solo across twelve months of paid use. And it ships tighter cadence than the Free tier.
- Q: Does SiteGuardian monitor SSL expiry like UptimeRobot's paid plans?
  A: Yes. SiteGuardian ships SSL expiry monitoring on every paid plan, included — no add-on. UptimeRobot only ships SSL expiry alerts on paid Solo and up; the Free tier does not. If SSL renewal is part of what you expect the watch to do, both are honest picks at parity on the paid tier.
- Q: Does SiteGuardian crawl my site for broken links like Oh Dear?
  A: Partially, and in a different way. SiteGuardian does not ship a full site crawler — neither does UptimeRobot. SiteGuardian does watch the URL list you configured during setup and re-probes it for broken links on the same cadence. Pick SiteGuardian if your URLs are already known and you want link breakage caught in the same loud email. Pick Oh Dear if you want discovery across every internal link.
- Q: Can SiteGuardian tell me when my checkout breaks?
  A: Yes. Configure your checkout URL on SiteGuardian and a separate probe runs against it on the same cadence as your uptime checks. UptimeRobot is strictly an HTTP-ping product — it will not flag a checkout that is slow but technically up, and it will not run a checkout-specific path probe.
- Q: Can SiteGuardian watch my contact form and report it when it stops sending?
  A: Yes. Add the form URL as a probe or wire a heartbeat monitor, and SiteGuardian pings it on the same cadence as your other URLs. UptimeRobot will only tell you that the form page itself is up.
