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

Pricing that respects you

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

Status pages included on every plan — not $29/mo extra.
