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.

We strive to provide you with the detail you need to understand what's going on.

VERIFICATION

Less false alarms

Every disruption is verified from multiple regions before you get alerted. A single network hiccup doesn't trigger unnecessary alarms, we only alert when a majority of probes vote to do so.

Unlike single-location monitors like Uptime Kuma, Larm confirms from multiple regions before alerting.

FLAT PRICING

Priced for sustainability

Most users get everything they need from the free plan, more demanding features are gated behind a paid plan. Larm is designed to be sustainable from the ground up.

The paid plans give you access to features like SMS alerts, custom domains for status pages, and more.
