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.

    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.

    With risk of tooting my own horn too much, this is exactly why I started my company https://checklyhq.com We approach it a bit different: we blur the lines between E2E testing and production monitoring.
