Larm is uptime monitoring for engineering teams. We check your websites, APIs, and services from multiple probe locations across multiple continents and use multi-probe voting to confirm outages before alerting โ€” so a single network hiccup doesn't become your team's 3 AM problem.

85% of monitoring alerts are false positives. That's not a statistic about bad services. It's a statistic about bad monitoring. When your team stops trusting their alerts, they stop responding to them. We built Larm to fix that.

How it works: every probe that checks your service casts a vote. Pass or fail. We require a strict majority across independent locations to change state. A timeout in Virginia while Frankfurt, Singapore, and Sรฃo Paulo see your service as healthy? Not an alert. When Larm sounds the alarm, it's real.

What you get: - HTTP, TCP, DNS, and heartbeat monitoring - Full request waterfall traces (DNS, TCP, TLS, TTFB, transfer) - Confirmation windows to filter brief blips - 14 alert integrations (Slack, PagerDuty, Discord, Email, SMS, and more) - Status pages that update automatically and survive your outage (static HTML on CDN) - SSL certificate expiry monitoring

The platform runs on EU-owned infrastructure (Hetzner, Germany). Your monitoring data is stored and processed in the EU.

Self-funded. No investors. Flat pricing: free with 15 monitors, Pro at $19/mo for 100 monitors and 10 team seats.

Possible disadvantages of UptimeRobot

  • Limited Advanced Features in Free Plan
    Some advanced features, such as shorter monitoring intervals and additional notification options, are only available in the paid plans.
  • Occasional False Positives
    Some users have reported experiencing false positives, where UptimeRobot incorrectly identifies downtime, potentially causing unnecessary concern.
  • SMS Alerts are Paid
    While email notifications are free, SMS alerts require additional cost, which might be a disadvantage for users who rely heavily on SMS for instant notifications.
  • Limited Server Locations
    The number of server locations for checking uptime is somewhat limited compared to competitors, which can affect the accuracy of uptime reporting in different geographies.
  • Custom Notifications Setup Complexity
    Setting up customized notifications can be somewhat cumbersome and not as straightforward, requiring users to navigate through multiple settings.
  • Limited Free Tier
    The free plan has some limitations, such as a maximum of 50 monitors and a 5-minute monitoring interval, which may not be sufficient for larger or mission-critical setups.
  • Advanced Features are Paid
    Most advanced features, including SMS alerts and more frequent monitoring, require a paid subscription, which might be a barrier for some users.
  • Data Retention
    The free tier only retains monitoring data for 3 months, which may be insufficient for long-term analysis and historical comparisons.
  • Integration Complexity
    Integrating UptimeRobot with other services and platforms might require some technical know-how, making it a bit challenging for non-technical users.

  • Best Website Monitoring Tools in 2026: What Engineering Teams Actually Use
    UptimeRobot is probably the first monitoring tool most developers encounter. Founded in 2010, it built its reputation on a generous free tier โ€” 50 monitors with 5-minute checks, no credit card required.
