Best alternatives to Larm in 2026
The classic uptime-monitoring problem isn't detecting downtime — it's detecting it reliably. A monitor running from one location can flag your site as "down" just because of a routing hiccup between that one probe and your server, triggering a false alert. Larm checks from four continents before confirming an incident, and pairs that with full request traces (DNS, TCP, TLS, and time-to-first-byte breakdowns) so when something is actually down, you get a concrete starting point for debugging instead of just a red dot. Beyond plain HTTP checks, it monitors TCP, DNS, and heartbeat/cron jobs, and produces branded public status pages with 90 days of history. It plugs into 14+ alerting integrations including incident.io and Grafana IRM, and tracks response-time percentiles (p50/p95/p99) over time rather than just a pass/fail state.

Gives an AI agent full, unsampled access to what's actually happening on a billion-plus mobile devices' worth of app sessions, so it can triage and fix a crash or bug itself instead of an engineer waiting days for the next app release to get more data.
