Why teams switch
Where SentinelWeb goes further than UptimeRobot
Beyond up-or-down
Uptime plus Core Web Vitals, synthetic user journeys and visual-regression diffs — not just an HTTP ping.
Security & SEO in one place
Security headers, malware and Safe Browsing, SEO indexability and SPF/DKIM/DMARC checks UptimeRobot doesn't run.
Incidents with root cause
Every failure becomes a timeline with root-cause notes — not a one-line 'site is down' email.
Where UptimeRobot may fit better
An honest take — UptimeRobot is the stronger pick when you need:
- Bigger free tier. UptimeRobot's free plan covers 50 monitors; SentinelWeb's free plan covers one site.
- Lower entry price. UptimeRobot Solo starts at $8/mo; SentinelWeb Pro starts at $12/mo.
- Built-in multi-location. UptimeRobot checks from multiple regions out of the box; SentinelWeb does not yet offer multi-location checks.
