UptimeRobot Alternative

A smaller, mobile-first
UptimeRobot alternative.

UptimeRobot is a mature monitoring platform with generous free limits, a Solo plan for faster checks, and larger Team, Scale, and Enterprise plans for bigger needs. Domain Monitor is intentionally narrower: a native iOS and Android app for small sites, indie projects, freelancers, and people who want simple monitoring from their phone, with a 1-month Pro trial and a $1.99/mo Pro plan.

What changed

When Domain Monitor may fit better

What UptimeRobot's free plan leaves out
UptimeRobot's Free plan covers 50 monitors at a 5-minute interval, and its Terms of Service allow commercial and business use. The gaps are certificate and domain checks: UptimeRobot's pricing page states that SSL monitoring is included only in paid plans, and domain-expiry monitoring is paid-only too. Both start on Solo, at $10/month or $9/month billed annually. Domain Monitor's free account is intentionally simple, but SSL expiry tracking is included on every tier.

UptimeRobot is the broader platform: more monitor types, larger free limits, faster paid intervals, integrations, and team features. Domain Monitor should not be read as a replacement for that scale. It is for a narrower workflow: checking a handful of important sites from a phone, getting push alerts, and running quick app-side diagnostics when something looks wrong.

The tradeoff is simple: choose UptimeRobot if you want a mature web dashboard and a broad monitoring platform; consider Domain Monitor if you want a smaller mobile-first status app with fewer moving parts.

The difference

A focused mobile-first workflow

UptimeRobot is a full web monitoring platform with a mobile app. Domain Monitor is a smaller app-first product for people who mostly want to manage a few monitors from their phone.

Mobile-first by scope
Domain Monitor's primary interface is the native app. The experience is designed around small screens, quick status checks, and lightweight diagnostics rather than a large web dashboard.
Free for any use
Domain Monitor's free account is intentionally limited, but it is usable for business, client, SaaS, or side-project sites, and SSL expiry tracking is included on every tier.
Lower-cost small-site plan
Domain Monitor Pro is $1.99/month. UptimeRobot Solo is $10/month monthly, or $9/month when billed annually ($108 upfront), and includes 60-second checks. Domain Monitor keeps the price lower by focusing on a smaller mobile-first feature set.
Cloud traceroute from the app
Domain Monitor includes on-demand cloud traceroute from the app, useful when you want quick route diagnostics without opening a laptop or terminal.

FAQ

Common questions about comparing UptimeRobot and Domain Monitor

What does UptimeRobot's free plan leave out?
UptimeRobot's Free plan includes 50 monitors at a 5-minute check interval, and its Terms of Service allow commercial and business use. The main gaps are SSL monitoring, which UptimeRobot's pricing page states is included only in paid plans, and domain-expiry monitoring, which is also paid-only. Both start on Solo: $10/month, or $9/month billed annually. Domain Monitor shows SSL expiry on every tier, free ones included; the expiry alerts are Pro.
Is Domain Monitor cheaper than UptimeRobot?
For small-site monitoring, yes: Domain Monitor Pro is $1.99/month. UptimeRobot Solo is $10/month monthly, or $9/month when billed annually ($108 upfront), for 10 monitors and 60-second checks. The better value depends on whether you need UptimeRobot's broader platform or a smaller mobile-first app.
What's UptimeRobot's check interval vs Domain Monitor?
UptimeRobot Free checks every 5 minutes, and UptimeRobot Solo checks every 60 seconds. Domain Monitor's Pro cloud checks run every 5 minutes. If sub-minute alerting is critical, UptimeRobot Solo is likely the stronger fit.
Does Domain Monitor have SSL monitoring?
Yes. Every HTTPS check reads the SSL certificate automatically. Domain Monitor tracks days remaining and warns you with escalating reminders from the threshold you choose — 3, 7, 14 or 30 days, or 60 on Pro. On the default 14-day setting that means alerts at 14, 7, 3 and 1 day out. Pro users get full certificate details in the app — issuer, validity dates, and SANs.
How many targets can I monitor?
With a free Domain Monitor account, you can monitor up to 30 targets. With Pro ($1.99/mo), you get up to 30 targets with automated cloud checks every 5 minutes. UptimeRobot Free has 50 monitors, and Solo has 10 monitors with faster checks; Team, Scale, and Enterprise scale further but are outside this small-site comparison.
