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.

Analysis of Larm.dev

Overall verdict

  • Larm.dev appears to be a niche or personal developer-related site/brand, but there is insufficient verifiable public information available to confirm its features, reliability, or reputation with confidence.

Why this product is good

  • Limited publicly available information makes it difficult to verify claims of quality or performance.
  • No widely recognized reviews, ratings, or user testimonials could be found to substantiate its reputation.
  • It may be a personal project, portfolio, or small-scale service rather than an established, widely-used product.
  • Without transparent documentation on pricing, support, or track record, potential users cannot easily assess risk versus benefit.

Recommended for

  • Users specifically seeking niche or personal developer tools who are willing to do their own due diligence.
  • Early adopters comfortable testing lesser-known or emerging services.
  • Those already familiar with the creator or team behind Larm.dev through other channels.
  • Not recommended for users requiring established, well-documented, and widely vetted solutions for critical or business use.

    Iโ€™ve been building an uptime monitor service for a while now, something that is genuinely reliable and only alerts you when something is actually going on. Also comes with very pretty status pages! Free tier is enough for most users, paid tier just exists to gate the stuff that is expensive to run like SMS alerts.

    Https://larm.dev, an uptime monitoring service with a focus on reliability and reduction in false positives. Iโ€™ve been building it for myself really but I figure itโ€™s worth sharing it with people in case someone else finds it useful too. Itโ€™s also a lot of fun to work on.
