Larm
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.

AlertKick
AlertKick combines server security and uptime monitoring in one product. A lightweight eBPF agent for Linux detects intrusions, file changes, rootkits, and SSH activity (login alerts, failed-attempt auto-blocking, maintenance lock), with detections mapped to MITRE ATT&CK and AI triage that attaches a written verdict to each alert. External monitors check HTTP, TCP, and DNS from outside the network, with response-time thresholds, SSL certificate expiry, and domain expiry from live registry RDAP data. Heartbeat monitors catch silent cron and backup failures, and public status pages keep users informed. Alerts flow through escalation policies and on-call rosters to email, Slack, Telegram, WhatsApp, SMS, and phone calls. Server changes are recorded and attributed for compliance evidence, with PCI DSS and SOX reports on Business plans. Setup is a one-line install per server. The free plan includes 10 uptime monitors and heartbeats - no card, commercial use allowed.
