Uptime monitoring that doesn't cry wolf.

UptimeRobot verifies downtime from multiple servers — but they're all within the same region. If there's a regional network issue in North America, all three checker nodes can fail simultaneously, and you get a 3 AM alert for nothing. False positives are the number one complaint in UptimeRobot reviews, and this is why.

Larm checks from six probe locations across three continents — Europe, North America, and Asia — and only alerts when a majority confirm the problem. A network hiccup in Virginia doesn't trigger an alert when Frankfurt and Singapore see your service as healthy. When Larm sounds the alarm, it's real.

UptimeRobot's November 2024 terms of service change restricts the free plan to non-commercial, personal use only. Use it for your SaaS, your client project, your startup? You're violating their terms.

Larm's free tier allows commercial use. No restrictions, no asterisks. We think monitoring is critical infrastructure, and restricting it based on whether you make money from your project doesn't make sense.

UptimeRobot tells you "down" or "up" with a response time number. That's useful for knowing something is wrong, but not for figuring out why.

Larm captures the full request waterfall for every check: DNS resolution, TCP connect, TLS handshake, time to first byte, content transfer. You see exactly which phase is slow, from which location, and how it's trending over time. When your API gets sluggish, you don't just see a number going up — you see that it's the TLS handshake from Frankfurt that's degrading.

UptimeRobot offers basic status pages, but custom domains and branding require a paid plan. Atlassian charges $29/mo for a status page alone.

Larm includes a branded status page on the free tier, tied directly to your monitors. Components update automatically when something goes down. Pro adds custom domains and removable branding at $19/mo — less than what Atlassian charges for just the page, and you get 100 monitors and the full monitoring platform on top.

UptimeRobot's interface is frequently described as "dated" and "looking like it was designed in 2012." Monitoring is something your team looks at every day. It should be pleasant to use.

Larm is built with a clean, engineer-focused interface. Real-time dashboards, response time charts, request waterfalls — designed with the same attention to detail you'd expect from tools like Linear or Notion.

UptimeRobot is US-based. Your monitoring data is stored on US infrastructure, subject to US jurisdiction.

Larm runs on EU-owned infrastructure under EU jurisdiction. Your check results and uptime data stay in Europe. If you're navigating GDPR, DORA, or NIS2, this matters. And even if you're not, it's nice to know where your data lives.
