Larm Reviews & Product Details

Larm is an uptime monitoring platform that checks websites, APIs, and services from multiple global locations and only alerts you when multiple probes confirm a problem. This multi-location verification eliminates the false positives that plague most monitoring tools. Larm supports HTTP, TCP, DNS, SSL certificate, and heartbeat/cron monitoring. Every HTTP check captures a full request waterfall (DNS, TCP, TLS, TTFB, transfer), giving you the data you need to debug performance issues, not just know something is down. Status pages are included on every tier, including the free plan. Pages are rendered as static HTML and served from a CDN, so they stay up even when your infrastructure doesn't. Custom domains, email subscribers, automated incident updates, and component grouping are supported on paid plans. Alerts can be sent through 13+ channels: Email, Slack, Discord, Microsoft Teams, Telegram, Webhooks, PagerDuty, incident.io, Grafana IRM, Pushover, ilert, ntfy, and Mattermost. Alerts are deduplicated per incident, so you get one notification, not one per probe. All customer data is stored and processed on EU-owned infrastructure. Probes run globally, but data stays in the EU. Pricing is flat per tier, not per user, per check, or per responder. The free plan includes 15 monitors, all check types, all probe locations, a status page, and is available for commercial use. Pro starts at $19/month (annual) with 100 monitors, 1-minute checks, and 10 team seats.
