About

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.

About

Uptime.com provides comprehensive, unified visibility into the availability and performance of critical services. Monitoring tools empower engineering, operations and SRE teams to maintain oversight of their web stack and respond to outages through customizable alerting channels. Uptime.com offers a broad set of monitoring capabilities, including web, network, and email. API and transaction checks offer synthetic monitoring to perform multi-step validations of critical flows and services. Monitor public and private resources through a unified interface that streamlines configuration and alerting. Set up and customize Status Pages with your company branding to communicate incidents and maintenance to both customers and internal teams. Provide a single-page overview that shows your overall service health at a glance. Robust and customizable SLA reporting allows stakeholders to stay informed on incidents and downtime.
