About
FourSight is multi-region uptime monitoring built to stop alert fatigue. Every check runs from four regions (US, Canada, Europe, Asia-Pacific) and a quorum-based consensus policy confirms an outage from more than one region before anyone is paged, so a single flaky vantage point never wakes you at 3 AM. Eight check types cover HTTP/uptime, keyword/content, SSL certificate expiry, DNS drift, domain expiry (RDAP), ping latency, TCP/UDP port checks and heartbeat monitoring for cron jobs and backups. Alerts go out by email, Slack, HMAC-signed webhooks and SMS, with escalation policies and maintenance windows to keep noise down. Public status pages are included on every tier (white-label with custom domains on Scale), plus incident management with timelines, multi-user organizations with roles, and uptime/latency history with regional breakdowns.

About
HostTracker is a 24/7 website monitoring service that helps businesses and webmasters track availability, performance and security from over 300 global locations.
With 13 monitor types, you can check HTTP/S, ping, TCP ports, transactions, web content, APIs, page speed, databases, server resources, SSL and domain expiry, plus Web Risk and DNS blacklist status.
Track response times and page load speeds, receive scheduled reports, and get alerts via email, SMS, voice call, Telegram, Slack, Viber, Discord, web push or webhooks. Alert delays, active hours and maintenance windows help prevent unnecessary notifications.
HostTracker also provides public status pages, a REST API and an MCP server for instant checks through AI assistants and developer tools.
The free plan includes 2 monitors. Paid plans start at $10/month, with a 30-day trial including 100 monitors at 1-minute checks - no credit card required.
