About FourSight

FourSight is a multi-region uptime monitoring platform: 8 check types — HTTP, ping, DNS, SSL expiry, domain expiry, port, keyword, and cron/heartbeat — validated from 4 global regions before an alert fires, so a single flaky vantage point never pages you at 3 AM. It has a free-forever plan that allows commercial use, flat published pricing, and status pages included on every tier.

Who builds it?

FourSight is built and operated by TetraCore, a software studio in Bowling Green, Ohio that builds and runs its own family of SaaS products — FourSight, CallsAround, LinkPilot, ItemStage, Franexis, and VoterCXM — and provides custom software, systems, and security services. TetraCore is led by its four founders, including W. Miller; the team that answers your support email is the team that carries the pager for this product.

Why does it exist?

TetraCore runs six production SaaS products and needed one dashboard that could watch all of them — uptime, SSL and domain expiry, DNS drift, ports, and the scheduled jobs that fail silently. FourSight monitors every TetraCore property in production; the product roadmap is driven by what operating that portfolio actually requires. We publish real plan limits and real prices instead of "unlimited" vagueness, and our comparison pages tell you plainly when a competitor is the better fit.

Not the same as…

FourSight (foursight.cloud) is not affiliated with foursight.com, the FourSight Thinking Profile assessment brand, or any other similarly named company. If you're looking for uptime monitoring, you're in the right place.
