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
Sentinel is a hosted monitoring service for websites, APIs, and network services. It runs HTTP/HTTPS, JSON/API, keyword, SSL certificate, DNS, domain expiration, ping, TCP port, cron job, and heartbeat checks, with response-time data and public status pages. Checks can run as often as every 15 seconds from 15 locations across six continents, with multi-location confirmation for outage alerts. Teams can receive notifications through email, SMS, Slack, Microsoft Teams, Discord, Telegram, PagerDuty, and webhooks. Sentinel also provides a REST API, command-line tools, a Terraform provider, and an MCP server for automation. A free plan is available, while paid plans start at $14 per month; plans include API access and do not charge per seat. The service is intended for developers, DevOps and SRE teams, and businesses that need to monitor service availability.
