What is FourSight?

FourSight is multi-region website and infrastructure monitoring for SaaS teams, indie developers, and agencies who are tired of false-positive alerts. Every check runs from probes in the United States, Canada, Europe, and Asia-Pacific, and a quorum-based consensus policy confirms incidents across multiple regions before paging your team — so a single flaky vantage point never wakes you at 3 AM.

Eight check types cover the full surface: HTTP/uptime, keyword/content, SSL certificate expiry, DNS drift detection, domain expiry (RDAP), ping latency, TCP/UDP port checks, and heartbeat/cron monitoring for background jobs. Alerts arrive via rich 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), alongside incident management with timelines, multi-user organizations with role-based access, and uptime/latency history with regional breakdowns. The free plan is permanent, allows commercial use, and needs no credit card; paid plans are flat-rate from $16/mo.
