Uptime Monitoring · 🇪🇺 EU Hosted · MCP Server
Know before your customers do.
Uptime monitoring with full request traces, multi-location verification, and status pages — built for engineering teams who care about the details.
Free for commercial use. No credit card required.
DEEP DATA
Not just up or down
Every check produces a full request trace — DNS resolution, TCP connect, TLS handshake, time to first byte, content transfer. See exactly which phase is slow, from which location, and how it's trending. Most tools give you a green dot. Larm gives you the whole signal.
VERIFICATION
Virtually no false alarms
Every incident is verified from multiple probe locations before you get alerted. A single network hiccup doesn't wake anyone up at 3 AM. When Larm sounds the alarm, it's real.
Unlike single-location monitors, Larm confirms from multiple probes before paging you.
FLAT PRICING

Flat tiers. No per-check billing. No per-responder surcharges. No surprises. You know what you'll pay before you sign up.
